Lubrication for roller bearings - what better to choose? Lubrication for bearings What better? High temperature lubricant for bearings Lubrication hub

The wheel bearings (SP) are obliged to be in perfect condition, since the overall condition of the car and the comfort in control directly depends on this node. Quite often about the presence of the hub driver remembers only when it makes itself felt as a squeal. In fact, the hubs are one of those driving components of the car, which are required to be lubricated and checked at maintenance, usually TO-2.

From ignorance, it is necessary to lubricate hub bearings And how often it is to do, today many car enthusiasts suffer. This part of the car assumes a fairly high load, which should be further further, but this function is slightly blocked when the friction is made between the shaft and the wheel bearing. Any friction has a negative, destructive nature, since the assemblies of the unit are wearing, so almost everything is necessary to lubricate. The benefit that the point is corrected, although it requires a speedy elimination.

If there was a non-standard sound, especially squealing in the area of \u200b\u200bthe leading wheels, then the trip should be postponed, especially long, until the item is lubricated.

Overview of lubricants with pluses and minuses

The question is whether it is possible to lubricate the hub bearings will not even rise, as the answer is obvious - yes. Another more important nuance, which is really worth paying attention, while the primary is, is it better to lubricate the hub bearings?

Today there are a lot of lubricants today, each different from other additives, adding and the most base, so there is no longer the same. It is important to note, since there should be no mixing of several types of lubricants in the bearing.

In general, it is necessary to disassemble what means to lubricate the hub bearing, initially determined with the genus of the main substance:

1. Solidal. Surely most car enthusiasts have a similar substance in the garage and it is quite suitable for the task, it is not necessary without deficiencies. Advantages are in a low price and high level Resistance to moisture, but the temperature characteristics are not too impressive. Another modification of solidol is CONSTALIN, which has opposite characteristics;

1. Litola. The most popular I. effective lubricants. Now they are easily accessible and cheap, while the variety of lithol products is very large. Such oils are perfectly coping with lubricant loaded nodes, do not affect moisture and heat-resistant. Additionally, anti-corrosion additives are used;

1. Molybdenum. Also excellent option, since it has all the above parameters, but also form a small, protective layer, preventing looting;

1. High temperature. It is infrequently required, they are also performed on the basis of litol, but withstand much higher temperatures, sometimes up to 1000 degrees. This effect is achieved due to the introduction of nickel and copper powders.

Choosing from the manufacturers of lubricants, the look is very scattered, but we advise you to turn to more well-known, eminent brands. Good product from Mobil, it is most often used. It is widely used, as it maintains a strong load on the car. You probably met such lubrication, it has blue.

Lubrication based on Molybdenum from Castrol is often recommended for vehicles that are experienced loads. The fact is that molybdenum envelops the driving parts with a dry layer and due to the additional protection of the mechanisms. It is also characteristic of the whole class what this option protects from scaling.

Divinol lubricants have increased plasticity. Also very flexible in use, since performance features Suitable for most cars.

Products from Molykote are also quite high-quality, so in the assortment there is a heat-resistant lubricant that does not react with most materials. Especially interesting is the version of Molykote BR 2 Plus, as it allows you to protect bearings from wear.

How to lubricate hub bearings

First of all, with a question, how to lubricate the hub bearing without removing it? Of course this is an option for those who just do not have the opportunity to remove this detail or time does not allow it to do. An important condition for this procedure is that the lubricant must necessarily be the same in the bearing itself and added. Usually, it is certainly difficult to learn the previous lubricant, so you still have to remove the hub.

So, how to lubricate the front hub bearing, without recroving it:

1. Need to install a car on the handbrake;
2. Raise the car
3. Remove the wheel, then the metal cap closes the hub;
4. Now it is necessary to remove the lock fixed ring using a screwdriver or subtle passage;
5. After that, access to the bearing is available, here it is necessary to add lubricants, then scroll through the hub.

Now it is known how to lubricate the hub bearing, but the way is much worse than the full analysis and further lubrication. In fact, in the previous embodiment, half of the procedure has already been performed from a full parsing of the hub, so you can simply add instructions.

1. After release from the fixture ring, it is necessary to remove the hub itself, and the brake disc should be kept;
2. Now it is worth leaving the bearing, it is done using the appropriate head and hammer;
3. Then it is necessary to clean the resulting part from the previous lubricant, probably it is very little or no, is not at all, it is performed using gasoline;
4. Visually check the integrity of the device and the absence of wear, then add the selected lubricant;
5. Scroll slightly and you can collect the hub.

Video instruction

Above the process of lubrication of the front wheel, how to lubricate the rear wheel bearing, or rather the main differences from the previous version will look further. Immediately it is necessary to make a reservation that in some cars the rear joint venture is completely unlated, and in the rest simply there is no direct access to it.

The process of parsing and removing the hub is approximately the same, it is impossible to extract the bearing itself. It is located in a closed block. It is necessary to promote, hide the lid to remove it. Next will need a syringe, better with a long nose. In the gap, which is located at the edges we carry the syringe with lubricant and squeeze up to filling the bearing, it should also scroll periodically.

Stories of car owners

Valery:

"I wondered if it was necessary to lubricate the hub bearing before installing, because it should be prepared for use. I decided that the manufacturer himself was puzzled by this problem, but, as practice showed - no, the next day I had to disassemble everything and lubricate again. "

Timely replacement of worn out parts of the car - the key to its long work. It often happens that coming to a hundred driver hears that it was possible to do without expensive repairs, if the car had drove a little earlier. In many ways, the work of the entire car depends on correctly selected lubricants, so the lubricant for the wheel bearings is so important. In this node there are ball or tapered roller bearings, for each of them you need your lubricant.

Bearings are enclosed in a closed clip, it should always be lubricant in it so that the parts do not grieve. When choosing such a lubricant, you need to pay attention to the following criteria:

1. Hemonslessness. This lubricant has to work in heavy conditions, so it should demonstrate stability to physico-chemical and mechanical effects even at high temperatures. It is also important that in winter frosts the lubricant thickening, and in the heat did not become very liquid.
2. The viscosity and strength of the composition. These parameters show the ability of lubricant material to be held on the details, and also characterize its turnover. The greater the viscosity indicator, the better, then all the surfaces of the bearings will work well without jamming.
3. Lubricant. This indicator determines how much the force of the friction of parts enclosed in the wheel hub will decrease. He is the most important for this car hub, since the course and movement of the entire car depends on the normal operation of the wheel. In case the selected oil has a low lubricant, the machine will work with jerks.
4. Resistance to corrosion. Rust - the main enemy of metal parts of the car, the lubricant for bearings will be able to protect them from its influence, for this it must have all the necessary qualities.
5. Anti-wear ability. It is desirable that oil in the period of operation helps to confront the hub details of wear and the appearance of scorches on them. When using a high-quality lubricant to replace parts, it will be necessary to carry out much less frequently. This will lead not only to savings on the purchase of the items of the hub, but also components for them.

Varieties used lubricants

Some mistakenly choose the lubricant for the bearings of the hub in its color, and not by properties, and make a serious error, since the inappropriate grease can cause damage to the bearing. Thinking about the choice which better lubricant For hub bearings, it should be known that it must be necessarily a three-component consisting of a lubricant, modifier and thickener. These components of the hub oil define its main properties. Before buying a lubricant, it is necessary to check its composition and characteristics declared by the manufacturer.

Depending on the effects of lubrication on the parts of the car, they are divided into several types.

1. High temperature. This type demonstrates the resistance to high temperatures, it retains its basic properties even at temperatures above 100 ° C. Composition of such a lubricant is copper or nickel.
2. Electrically conductive. Ideal for onboard power grid, as it protects its connecting wires, rechargeable terminals and corrosion relays.
3. Preservative. A simple type of lubricant that protects metallic parts from corrosion influence, but they can wash off from the surfaces of parts ordinary water. Most often, they are used to preserve parts.
4. Molybdenum. It is precisely it is used for mobile elements of the car, it forms a protective film on their surface, eliminates the overheating of the parts and the formation of scaling on them.
5. Lithium. This type includes lithols and similar compounds, they are intended to protect bearings and interacting units.

All the lubricants described are designed for certain purposes and nodes, so you should seriously approach their choice so as not to harm the car.

What lubricant to choose and when?

Change the lubricant for the hub bearings is preferably after every 35 - 45 thousand mileage, the allowable kilometer depends on the conditions of the intensity of the machine's use. The factors to pay attention to when purchasing it:

• the magnitude of the load transmitted to the hub;
• the intensity of driving by car, how often it is used and for which distances is transporting its owner;
• bearing steel brand;
• type of parts used in the hub;
• protection of the node from moisture and mud;
• frequency and speed of rotation of the hub elements.

In most, experienced motorists acquire high-temperature lithium-type strokes.

If the material responds to elevated temperatures, it can simply find out from the hub node, and the part in it will work "on dry". If suddenly the lubricant of a certain type is over, and there is no place in stock, then it is impossible to attach another type, as they work in different conditions.

Before lubricating the bearing hub, it is necessary to prepare it: clean and wash with gasoline. The oil is poured strictly in a certain dosage, otherwise, with its disadvantage, the bearing unit can be jammed, and when an excessive excess will be overflowing. To determine the optimal amount of lubricant, you need to explore the vehicle's vehicle.

If we speak specifically about certain types of lubricants that can be used for hub bearings, then three of them can be distinguished.

Molybdenum-containing lubricants

They effectively protect the wheel assembly quite quite, are mainly made from Molybdenum disulfide, which is able to extend the life of the bearing and protect it from wear. In favor of the choice of precisely this lubricant, its ability to resist the development of corrosion processes. The main component of this oil leaves on the surface of the details of the film, due to which the metal becomes resistant to the oxidative effect of the external environment. The life life of such a lubrication is 100 thousand km, the hub bearing can also be used to approximately, it turns out that one lubrication will be enough until the old bearing is replaced.

But this lubricant has disadvantages, among which they allocate:

• interaction with water;
• if the hub will occur, the physico-chemical properties of lubricant may suffer. In this case, it is necessary to replace all the lubricant, and at the same time check if it did not affect the state of rubbing parts;
• lubricants of this type are rapidly polluted, and inclusions falling on them lower lubricant properties to resist friction;
• the effects of high temperatures on molybdenum-containing lubricant begins to manifest at high speeds. This failure can be calculated if you open the cap and check the color of the liquid under them, if there is such a problem, its color will be blue.

The market presents molybdenum-containing lubricants of domestic brands: "Slsus-4" and "Fiol", and foreign manufacturers offer: "Mobil", "Texaco", "Esso" and "Castrol" (BP).

Lithium-containing lubricants

They are based on lithium dissolved in organic acids. Such oil refers to a universal type, appearance It can be found in the characteristic light yellow shade. The good viscosity of the material provides optimal lubrication of all moving parts, due to which friction is reduced between them.

Lithium lubricants can withstand, without losing their operational properties, up to 110 thousand runs. They can return to their operational properties Even after a strong overheating of the node.

The disadvantages of this material include:

• the average degree of corrosion resistance;
• some polymer materials are not suitable for some polymeric materials.

Buy lithium oil domestic producer It is possible under the brand "Litol 24", and among foreign brands they use much popular: "Very Lube", "British Petroleum" and "Renolit".

High temperature lubricants

They have copper and nickel powders in their composition, which give them high oxidative stability and resistant to high temperatures. Even in extreme conditions, bearings with such a lubricant are working trouble-free, their working temperature May lie in the range from - 40 to + 180 ° C. They should be adjusted by novice car enthusiasts, who often have emergency braking on the roads. High-quality additives that are part of these lubricants are eliminating the oil resistance to washing, oxidation and thermocorrosion. An excellent representative of this type of lubricant is "Blue" (MS 1510).

Knowing why the lubricant is needed in the hub bearings, it becomes easier to choose it, based on the criteria and factors affecting the required characteristics of the oil. In order not to doubt your choice, you should read the operating instructions attached to the auto, as well as read the recommendations of its manufacturer. Do not choose an expensive oil, but also it is impossible to save on it, it is advisable to find the optimal combination of its quality and a receiving price.

All rotating nodes vehicle These are simple and reliable rolling bearings that do not require additional maintenance, except that the periodic lubricant does not prevent them. Lubrication for wheel bearings increases their characteristics and extends the operational resource.

The generation of the bearing hub is accompanied by mandatory noise, and if you leave this problem not solved, the bearing simply can jam. It is not difficult to imagine what happens if it happens at high speed.

Nutritional bearing is not necessary: \u200b\u200bperiodic replacement of lubrication and proper adjustment. In compliance with these requirements, the part will work out the full period of operation of the vehicle, however, if high-quality steel was used for its manufacture, and the lubricating composition fully complies with the manufacturer's requirements.

Types of consistant lubricants

The best lubricant for the hub bearing in the opinion of most vehicle owners is the one that will keep well to match all high-quality characteristics. Many simply choose the color lubricant, and not by its properties. Such a choice cannot be called justified, since incorrectly selected grease can damage the bearing.

In no dependence on how the bearing of the hub is arranged, it should be lubricated only by a consistent or plastic material, the liquid substance is not suitable for this. Note that in addition to the main basic properties, the lubricant of the plastic consistency plays the role of the seal, additionally protecting the element. For the wheel bearings, three-component lubricants are applied, which include:

1. Modifier.
2. Lubricant.
3. Thickener.

These components define the main properties. consistant materials. Therefore, to determine: what lubricant to use should be paid attention to its composition and main characteristics. Separately, it is worth mentioning about lubrication types. List them:

Preservative

One of the simplest types. The main purpose is the protection of metal elements from corrosion. A short time is held on the surface, since it is washed off with water. Ideal for preservation of parts.

Electrically conductive

It is intended for servicing the onboard power supply of vehicles. Protects the connections of wires, relays, battery terminals, etc. from the formation of corrosion foci on them.

High temperature

Its main feature is the resistance to the effects of high temperature. Lubrication does not lose its properties even when heated to 1000 or more degrees. In its composition there are powders of various metals, it is often nickel or copper.

Lithium

Molybdenum

Ideal for lubricating moving elements, because they cover their surface with a thin, protective film that prevents the formation of scaling and provides an efficient heat sink.

This is the entire main lubricant that will be required to serve the vehicle. As can be seen, these lubricants are not interchangeable, so it is extremely important not to be mistaken with the area of \u200b\u200btheir use, since it can be seriously harvested.

Features design bearing hub

Since the hub bearings have several embodiments of their design before deciding what to lubricate, and how to do it properly, it will be more logical to familiarize yourself with their device.

All hub bearings in no matter of whether they are located in the front or rear parts of the car are included in the design of the leading or driven wheels, are constantly exposed to high temperature and mechanical loads. Accordingly, they should be made from high-strength materials that will ensure the stable and reliable operation of the bearing throughout the entire period of operation.

Bearings used in the car hubs can be:

• conical roller;
• ball.

They have both their advantages and disadvantages. However, their performance and operational resource depends solely on the working conditions and the magnitude of the load. With an insufficient amount of lubricating material or absence, steel parts are produced faster. Each type of wheel bearings is required certain greasethat should be properly pick up. Note that in addition to lubrication, the durability of the element also affects how correctly it is installed.

For each type of bearings, the manufacturer indicates its torque of the tightening, which must be fulfilled, because if the part is dragging, it all equals it after a certain period of time due to continuous overheating. Not enough tightened element is simply scattered.

We emphasize that it is impossible to calculate the required torque of the tightening. For example, a two-row design should be tightened so that the balls are fluently moved in their tracks. Only with this condition, the part will work normally and it will not be embedded.

When to lubricate, and which lubricant to choose?

The regulation of automakers has been established for replacing the lubrication of the movable elements of the hub, which is 35-45 thousand km of run, depending on the intensity and operating conditions of the vehicle. In compliance with this rule, even if the details are regularly lubricated, at least "Litol-24", there should be no serious problems with them.

However, the lubricants for the bearings of the hubs there are quite a lot, and what is suitable for one vehicle model is not necessarily suitable for another. The technical book of the car shows the recommendations regarding the use of lubricant for various aggregates and nodes. For hub bearings, lubricant is selected by the following criteria:

1. Steel grade.
2. Load magnitude.
3. The intensity of the operation of the car.
4. Detail type.
5. Speed \u200b\u200band speed.
6. Protection from dirt and moisture.

For most hub bearings, ordinary high-temperature lithium lubricants will be completely suitable. Material with poor resistance to elevated temperature counting from the element, because of which it will function on dry. It is strictly forbidden to mix lubricants, as they are intended for various types of bearings, and work in various conditions.

As part of the publication, it is also worth touched upon the issue of dosage of lubricant material. It is worth noting that before the lubricant, the hub bearing must be carefully cleaned and rinse with gasoline. Both excess and lack of lubricant negatively affect the operation of the hub moving element. In the first case, the extra material to fall out of the cluster, and in the second - the bearing can simply swam. The optimal amount of lubrication is indicated in the technical book of the vehicle.

How to lubricate the wheel bearing

The removal procedure of the hub must be familiar more and less experimental motorists. It requires a standard set of plumbing tools. We will tell you more about how to lubricate the hub bearing. Before performing this procedure, it is necessary to prepare the following consumables:

• new nave nuts;
• selns;
• lubrication;
• washing liquid (for example, gasoline);
• rag.

The hub is dismantled from the car as follows:

1. The car rises by the jack from the side, in which the repair activities will be carried out, after which the wheel is removed.
2. Unscrew and removed the wheel cap.
3. The brake mechanism is removed, after which the nave nuts are twisted and the lock washer is dismantled.
4. After that, it is necessary to remove the bearing separator.
5. Now you can dismantle the hub.

It is necessary to wipe it in front of the bearing in front of the bearing and rinse with gasoline, and then lay lubricant. The assembly is performed in the reverse order.

How to lubricate not collapsible hub?

You can lubricate the bearing and without removing the hubs, since most of them are not published. In their designs, the bearing and the flange hub represent a single part. Lubrication is of great difficulty, and according to most motorists, such a procedure is unacceptable. However, it is possible to lubricate bearings with no collapsible hubs.

To perform this procedure, a special syringe will be required, with which the consistant substance is pressed into the part. But, there is another way: a small diameter drill can drill a few holes in a metal plate, which closes the element, and through them with the help of a medical syringe to pressed the required amount of lubrication. After that, the holes should be seal or cold welding.

There is nothing complicated in maintaining the hub bearings, but the benefits of its execution is quite noticeable, because it allows you to extend to increase the operational period of the element.

Bearings, invented more than a hundred years ago, became an indispensable detail in any rotating mechanism - they are able to significantly reduce friction compared to their analogues, as well as for individual components. The car also uses many bearings - among them it is necessary to note the details in the engine and transmission, as well as in the hubs of the wheel. The latter usually pay less attention to, considering them almost "eternal". However, it is better to abandon this approach, since the hub bearing swapping at a huge speed can cause a serious accident. To avoid such problems and ensure reliability of the chassis of the car, you should know what kind of lubricant for the hub bearings is better.

What lubricants can not be used?

First of all, you need to say that not every grease will be good option To reduce the friction of the hub bearings. This is due to the special conditions of operation of such a node - it moves with a very high speed and heats up to a high temperature. It is the last circumstance that is the reason for the refusal of lubricants based on synthetic hydrocarbons - they begin to collapse already when heated to 45-60 degrees. This group belongs silicone and vaseline compositions that are widely represented on russian market. Each motorist should be remembered that hydrocarbon lubricants are conservative and are not suitable for processing such high-loaded parts as the hub bearings.

It is also better not to acquire lubricant on a graphite basis, since it contains a sufficiently large number of abrasive particles leading to accelerated wear of the bearing housing. Graphite lubricants Used to process sediments or to protect against the corrosion of the springs. When packing such a fund into the wheel bearings, the repair of the chassis is to be done after 25-30 thousand kilometers, although the nominal service life of such parts reaches 100-120 thousand kilometers.

Quickly destroy the wheel bearings are capable and lubricant based on calcium or sodium. Such tools are able to effectively deal with friction, but they cannot prevent the spread of corrosion. At the same time, the exploitation of the wheel bearings is carried out in very difficult conditions, so they can quickly fail without proper protection. It is also worth abandoning the use of lubricants with iron and zinc, even if they are intended for bearings - most likely, such funds must be used in industrial equipment.

Best tools

Based on disulfide molybdenum

One of best tools, protecting wheel bearings from destruction, is a lubricant containing a large number of molybdenum disulfide. This metal salt is capable of significantly reduce friction force, reducing the wear rate of the entire node. In addition, lubricants made using such technology are able to stop the spread of corrosion due to the formation of a very dense indestructible film on the surface of the processed part. The service life is equal to the duration of the operation of the wheel bearings themselves - more than 100 thousand kilometers, so with a competent installation of any problems with chassis There will be no car.

Of course, even such high-tech lubricant can not do without certain disadvantages - first of all, they are presented with sensitivity to moisture. If the housing of the hub will be depositized, the lubricant is better to change, carefully checking the condition of the bearing, which may be irreversible damage. In addition, lubricants based on disulfide molybdenum are quickly contaminated, and when the abrasive particles appear in them, the efficiency of combating friction is significantly reduced.

The lubricant created using the molybdenum disulfide is also able to collapse at particularly high temperatures, although these indicators are much larger for it than for the previously mentioned hydrocarbon synthetic agents. Therefore, after a long ride at high speed, it is desirable to regularly lean the lids of the bearings housings to check their condition - the first indicator of their excessive wear will become a bluish color, after which the broken part will begin to manifest itself with a strong buzz. For processing hub bearings, you can use lubricant domestic production, for example, Fiol, and when it can be used, you can buy an more expensive tool SHRUS-4, although it will slightly decrease the service life of the node. If you prefer to use overseas manufacturers, pay special attention to the following brands:

• Texaco;
• Castrol (BP);
• ESSO;
• LIQUI MOLY;
• Mobil.

Based on lithium

Already a long time ago a universal grease was developed, which was based on lithium dissolved in organic acids. When foaming and adding a thickener, a yellowish substance is obtained, which is easily burdened with a finger or a special tool, but it does not fall out of the jar. Lithium lubricants are considered an ideal option to combat friction - they provide a significant reduction in loads, which leads to a decrease in the depreciation rate of individual parts. Due to this, the lifetime of the bearing during processing such a composition increases to the maximum, which allows you to get confidence in the reliability of the chassis of the car. TO strong sides Lithium-based funds include durability - the lubricant does not lose its properties and to 100-110 thousand mileage kilometers, although it is better to replace the part for security.

Due to this, lithium lubricants consider the ideal option to ensure the safety of bearings, although in some other areas the result with their help is not so good. The disadvantage of these funds is the average corrosion resistance in comparison with alternative compositions, therefore, with a violation of the tightness of the bearings, the lubricant material is also worth changed. In addition, the minus is the ability of organic acids based on lithium lubricants to dissolve some polymer compounds. Therefore, before purchasing such funds, pay attention to the instruction manual for the car - it is quite possible that you will find an indication of the inadmissibility of their application.

Now lithium-based lubricant is made only by several foreign companies, among which you need to name British Petroleum, Very Lube and Renolit. However, you can use to protect the wheel bearings and a relatively inexpensive domestic equivalent represented by the means called Litol-24. Unlike other compositions, Litol copes perfectly with elevated loads and high temperatures, providing maximum durability of parts. In addition to the big durability and, the advantage of domestic lubrication can be called widespread - it can be purchased in any car or construction store.

How to lubricate the hub bearing?

To apply lubricant on the hub bearing, you must first get to it. Before disassembling, you should put a car in a flat place and fix it to prevent accidental movement. Before removing the wheels, do not forget to loosen the hub bolt, turning it counterclockwise - if you forget to do it, you will have to spend a lot of extra time. When the bolt is weakened, lift the car to the jack and carefully dismantle the wheel, trying not to thread the threads of his bolts.

Gently unscrew the mounting bolts brake calipers And, holding shoes with hands, remove this item from the wheel hub. To get to the bearings, you may also need to dismantle the ball support and the rack - while you need to unscrew 2-4 bolts, which hold such components and gently take them to the side, not allowing strong blows and oscillations. In some cases, it is necessary to knock off the semi-axis - putting a wooden lining or a wide metal mandrel on it, apply a few non-links and then pull the edge of the hub with your hands.

You will also have to disassemble the hub itself - it is also done with the help of wide metal mandrels, although here you can already be slightly stronger. Reaching the bearing, bulk it using the mandrel size is smaller - be neat so as not to damage the housing housing. Please note that the hub bearing consists of two asymmetrical parts - remember their position to subsequently collect the node correctly. Taking the old parts of the bearing, check that the balls left the balls falling in the hub, as well as the old lubricant - for this you will need to wash the cavity, and then wipe it thoroughly with large paper napkins.

Lubrication of wheel bearings is usually made by hand - special tools are used extremely rare. In total, you will need to fill in one detail about 30-40 grams of thick material, carefully sealing it and watching the uniformity of application. Alternately, set the two parts of the bearing, simply lubricating them with a lack of packing. To significantly speed up the process and not damage the plastic protective casing of the part, use the old bearing instead of the mandrel and hit the hammer on it. Make the hub assembly in the reverse order.

Maximum reliability of the chassis

To decide which lubricant will be to protect the wheel bearings, be sure to pay attention to reading the instruction manual for the car. As a rule, the manufacturer indicates a type of composition that is allowed to use or even a specific product name. If there are no such guidelines, you can use lithium lubricantwhich provides excellent protection against accelerated wear and corrosion. The domestic composition of Litol-24 and foreign analogues have almost the same efficacy of use, so you can not pay attention to the trademark when buying. In addition, an alternative option is a lubricant based on Molybdenum disulfide, although it is not so resistant to moisture and has some other features.

The wheel bearings (SP) are obliged to be in perfect condition, since the overall condition of the car and the comfort in control directly depends on this node. Quite often about the presence of the hub driver remembers only when it makes itself felt as a squeal. In fact, the hubs are one of those driving components of the car, which are obliged to be lubricated and checked for maintenance, usually TO-2.

From ignorance, it is necessary to lubricate the hub bearings and how often it is to do, today many car enthusiasts suffer. This part of the car assumes a fairly high load, which should be further further, but this function is slightly blocked when the friction is made between the shaft and the wheel bearing. Any friction has a negative, destructive nature, since the assemblies of the unit are wearing, so almost everything is necessary to lubricate. The benefit that the point is corrected, although it requires a speedy elimination.

If there was a non-standard sound, especially squealing in the area of \u200b\u200bthe leading wheels, then the trip should be postponed, especially long, until the item is lubricated.

Overview of lubricants with pluses and minuses.

The question is whether it is possible to lubricate the hub bearing will not even rise, since the answer is obvious - yes. Another more important nuance, which is really worth paying attention, while the primary is, is it better to lubricate the hub bearings?

Today there are a lot of lubricants today, each different from other additives, adding and the most base, so there is no longer the same. It is important to note, since there should be no mixing of several types of lubricants in the bearing.

In general, it is necessary to disassemble what means to lubricate the hub bearing, initially determined with the genus of the main substance:

1. Solidal. Surely most car enthusiasts have a similar substance in the garage and it is quite suitable for the task, it is not necessary without deficiencies. The advantages are in a low price and high level of resistance to moisture, but the temperature characteristics are not too impressive. Another modification of solidol is CONSTALIN, which has opposite characteristics;

1. Litola. The most popular and efficient lubricants. Now they are easily accessible and cheap, while the variety of lithol products is very large. Such oils are perfectly coping with lubricant loaded nodes, do not affect moisture and heat-resistant. Additionally, anti-corrosion additives are used;

1. Molybdenum. Also an excellent option, as it has all the above parameters, but also form a small, protective layer, preventing looting;

1. High temperature. It is infrequently required, they are also performed on the basis of litol, but withstand much higher temperatures, sometimes up to 1000 degrees. This effect is achieved due to the introduction of nickel and copper powders.

Choosing from the manufacturers of lubricants, the look is very scattered, but we advise you to turn to more well-known, eminent brands. Good product from Mobil, it is most often used. It is widely used, as it maintains a strong load on the car. You probably met such lubrication, it has blue.

Lubrication based on Molybdenum from Castrol is often recommended for vehicles that are experienced loads. The fact is that molybdenum envelops the driving parts with a dry layer and due to the additional protection of the mechanisms. It is also characteristic of the whole class what this option protects from scaling.

Divinol lubricants have increased plasticity. It is also very flexible to use, as performance characteristics are suitable for most cars.

Products from Molykote are also quite high-quality, so in the assortment there is a heat-resistant lubricant that does not react with most materials. Especially interesting is the version of Molykote BR 2 Plus, as it allows you to protect bearings from wear.

How to lubricate the hub bearing (removing, without removing) - instructions.

First of all, with a question, how to lubricate the hub bearing without removing it? Of course this is an option for those who simply do not have the ability to remove this item or time does not allow it to do. An important condition for this procedure is that the lubricant must necessarily be the same in the bearing itself and added. Usually, it is certainly difficult to learn the previous lubricant, so you still have to remove the hub.

So, how to lubricate the front hub bearing, without recroving it:

1. Need to install a car on the handbrake;
2. Lift the car in;
3. Remove the wheel, then the metal cap closes the hub;
4. Now it is necessary to remove the lock fixed ring using a screwdriver or subtle passage;
5. After that, access to the bearing is available, here it is necessary to add lubricants, then scroll through the hub.

Now it is known how to lubricate this node, but the way is much worse than the full analysis and further lubrication. In fact, in the previous embodiment, half of the procedure has already been performed from a full parsing of the hub, so you can simply add instructions.

1. After release from the fixture ring, it is necessary to remove the hub itself, and the brake disc should be kept;
2. Now it is worth leaving the bearing, it is done using the appropriate head and hammer;
3. Then it is necessary to clean the resulting part from the previous lubricant, probably it is very little or no, is not at all, it is performed using gasoline;
4. Visually check the integrity of the device and the absence of wear, then add the selected lubricant;
5. Scroll slightly and you can collect the hub.

Video instruction.

Above the process of lubrication of the front wheel, how to lubricate the rear wheel bearing, or rather the main differences from the previous version will look further. Immediately it is necessary to make a reservation that in some cars the rear joint venture is completely unlated, and in the rest simply there is no direct access to it.

The process of parsing and removing the hub is approximately the same, it is impossible to extract the bearing itself. It is located in a closed block. It is necessary to promote, hide the lid to remove it. Next will need a syringe, better with a long nose. In the gap, which is located at the edges we carry the syringe with lubricant and squeeze up to filling the bearing, it should also scroll periodically.

Stories of car owners.

Valery:

"I wondered if it was necessary to lubricate the hub bearing before installing, because it should be prepared for use. I decided that the manufacturer himself was puzzled by this problem, but, as practice showed - no, the next day I had to disassemble everything and lubricate again. "

The owner of the VAZ 2114:

"He began to observe that a certain squeal occurs emanating from the rear wheel. There was a similar sound only when the speed developed about 90 km, nor below, neither above was not the above. Reaching and removing the rear hub, it became obviously an extremely small lubricant content, added and everything became fine. "

Kirill:

"Once lubricated the bearing and everything began to work as a watch, but after a while the problem returned, and soon. Again I had to disassemble the wheel and, when the hub got to the fixed ring, everything became obvious, it was poorly fixed and because of this, the lubricant went out, and the bearings got stuck garbage. I cleaned, smeared and swallow began to fly again. "
