The rear stabilizer bushing that. Replacing bushings of transverse stability stabilizer. Service life and price

Many different gaskets and rubber sleeves are installed on automotive mechanisms for normal operation or as a connecting element. But such elements wear out quite quickly due to increased intensity. As a result, the backlash appears in them, which makes a trip by car unsafe. In addition, worn out sleeves can lead to more serious faults.

This also applies to the sleeves installed on the stabilizer. If you have noticed the noise in the car suspension while driving, it may mean that it is necessary to replace the stabilizer bushings. Moreover, it concerns the replacement of the front and rear sleeves. This will be discussed in more detail in this article.

In the field of mechanical engineering, the stabilizer appeared together with the first cars, maximum speed which exceeded the mark of 20 km / h. Due to the larger rolls arising from turning, there was a need to install this component. The main goal of the stabilizer is to protect vehicle From tipping, because during the turn, the load on the external wheels increases, and the internal, on the contrary, is reduced. This leads to rocking the car. The stabilizer makes it more stable on the road without giving turning over.

On a note! All auto pendants are equipped with a stabilizer, not only in front, but also from behind. The stabilizer is not needed only if a torsion beam is installed in the back of the vehicle: the functions of the stabilizer will be naked on the suspension itself.

The design of the stabilizer of many cars is a P-shaped metal rod, made of spring steel. For fastening the device to the body, special clamps and sleeves are used, allowing the stabilizer to rotate. For greater stability of the car and increase the elasticity of the stabilizer, bushings are used - all shots from various suspension elements come on them.

What are the sleeves and why they need

The main task of the sleeves is a decrease in the noise of the suspension when moving and fastening the stabilizer to the car body. As a rule, they are produced from two materials: polyurethane and rubber. Details have high elasticity and durability, because of which the screens and knocks when changing the height of any of the wheels are missing. In addition, to attach the stabilizer to the body is hard not possible, since the distance from the place of attachment to the edge of the stabilizer when the bending changes.

Often, various sounds that occur when driving and steep turns - screens, knocks and so on can be said about the fault of the bushings. This phenomenon is associated with the loss of elasticity of the sleeve, as a result of which it becomes very tough. Also, dust or sand can be stuffed under this item.

Signs of worn wear

The design parameters of the sleeve are a bit similar to the parameters of the ball support, only the sleeve has one unpleasant feature - it is wearing, as a result of which the item becomes faulty. It should also be noted that riding a car with damaged suspension elements is unsafe, so if you revealed a malfunction stabilizer bushings - Try to replace it as soon as possible. Determine the unsuitability of the driver's sleeve for the driver will not be much difficulty, because when moving, the vehicle management will become difficult.

In most cases, the worn out of the stabilizer bushings is accompanied by characteristic sounds in the suspension area, which increase when accelerating the car. Overcoming road irregularities (bumps, pits, pebbles on the road) causes drivers to shudder from the occurring strikes at the bottom of the car. Attentive driver will immediately notice foreign Summas And minor deterioration in the management of the car, as well as to be clarified by the cause of this problem.

So that the bushings and suspension are not brought to such a state, it is recommended to regularly carry out technical inspections for all design elements. It is necessary to carry out the close diagnostics of the sleeve.

Diagnostics

The diagnosis of the stabilizer bushings is to perform two steps:

• visual assessment;
• Rendering mechanical impact.

It is necessary to put the car on the overpass or a hole to check the gum. Some use the lift for this purpose, but it can be dangerous. The fact is that the diagnostics of the sleeves involves a strong jerking of the stabilizer, as a result of which the car swings and can fall. The same applies to the jacks, from which the car jumps much faster than from the lift. This can lead to the saddest consequences, since the weight of the car is very large, and all this metal construction can pick up mechanics.

The task of the visual assessment is to inspect the gum for breaks and cracks. If even one crack was detected on one piece, then you need to change the whole set completely. Mechanical impact requires coarse male power - take the stabilizer next to the sleeve, which connects the item with the body, and pull it hard in all directions. In the process there may be stuffs or screens. This means that the bushings must be replaced. In the process of mechanical exposure, do not be afraid to damage the stabilizer or the bushings themselves - they are intended for a strong load, so your attempts to check the serviceability of the parts will not be able to cause them any harm.

What will be needed to replace

To accomplish this work, you will not need a lot of tools, but still need to be prepared in advance.

To replace the stabilizer bushings, you need:

• jack;
• line or caliper;
• special wrench extension;
• ratchet key;
• caucasus, one by 13, and the other by 10;
• elongated end heads or ordinary (14,13).

It is worth noting that this is only the main set of tools, you can actually need others. This is due to the need to unscrew the fastening nuts when the stabilizer is removed. In this and all the snag, because the usual key will not be able to unscrew the fastening nuts (during operation they are bought to the part). In this case, many are resorted to emergency measures - the use of hacksaws for metal or bulgaria. In the process of release of nuts, the rack of the stabilizer may be damaged, so that you can no longer by one replacement of the rubber band.

The jack may be needed in two cases: to raise the car and to return the rod of the stabilizer in initial positionIf you can not do it with your hands or by scrap. If the rod is still left a little to the side, then lift the back of the car. This should be enough for the item returned to his place.

You can also not cope with the replacement of the sleeves without the bushings of the stabilizer. You can get them without leaving home. The benefit for this is the Internet with which you can order the desired detail with the delivery to the house. You can also visit the automotive store or market. Consider the fact that for each model of the car you need certain gum, so before buying, do not be lazy, first remove the old parts for comparison in the store. In addition, they can survive the serial number, which will facilitate the process of choice. Otherwise, you risk spending money on a detail that is not suitable for your car.

The quality of the details also plays an important role, because not only natural rubber can be used for their production, but also artificial. If you have a choice of: buy a bush from a natural material or artificial, then it is better to prefer the last option (it is more durable).

Replacing the front sleeves

You can perform this procedure in two ways: to raise one side of the car or two jack. The second method is considered more laborious, but many motorists prefer it to him. In addition, with the two sides of the machine, the installation and removal of the bushings can be carried out much easier. The main thing is safety and adherence step by step instructionswhich is shown below.

Step 1. To begin with, buy details for replacement. You can take the original or analogue - it depends on your preferences and financial capabilities. Although even if you choose the original, you will pay no more than 400 rubles for the items.

Step 2. By installing the anti-collective wedges, subdominate the car. Then unscrew the fastening bolt of the sleeve brackets. To do this, you will need a key to 12. If the bolt is not spinning, then process it WD-40 or how this tool is called the people - "Woveshka". After 5-10 minutes, the fastener can be easily unscrewed.

Step 3. After the mounting bolts are unscrewed, remove the locking bracket a little up. It's very difficult for bare hands, so use a screwdriver, slightly tended by it with extreme part of the bracket.

Step 4. Carefully remove the sleeve. It is not necessary to use any tools for this, the bushing is easily removed and so. After removal, inspect the item for damage, signs of worn out or cracks.

Step 5. Install the new sleeve in your place and lower the fixing bracket on it. It is advisable to handle the surface of the sleeve with a small amount graphite lubricantSo that the bracket is established on the gum without problems. After that, tighten the fastening bolt, trying not to thread the thread. Otherwise, you will add some concerns.

Replacing the rear sleeves

The rear stabilizer mount is carried out due to two sleeves made of rubber. As a rule, during the operation of the car, these parts lose their strength and elasticity, as a result of which they are no longer able to fulfill their basic functions. As a result, rear suspension When moving begins to knock. If you heard the characteristic sounds, it means that you need to replace the rear sleeves. As with the replacement of the front sleeves, it is necessary to raise the car to the jack. It is desirable to raise two sides at once - right and left. Now proceed to work.

Step 1. Get started to start new rubber bands. In this case, they come complete with a special lubricant, which extends the operational period of details and facilitates the replacement process.

Step 2. Clean the surface of the stabilizer and the fastener from dust. To do this, use coarse sandpaper or rigid brushed. Then splash a little WD-40 to the bolt so that it is easier to unscrew.

Step 3. Unscrew the fastening bolt to 14, and then slightly press the pliers bracket so that then you could remove the item. As you can see, the processes for the replacement of the front and rear sleeve are not much different from each other, except for the separated bolt.

Step 4. Lubricate the stabilizer with a liquid from the kit, after which you can install a new sleeve. Do not confuse the parties part, install it as the same side as before. Otherwise, you risk significantly shortening the life of a completely new part.

Step 5. Gently install the stabilizer bracket in its place and secure it with a bolt. In this case, you need to be careful not to damage the fastening element or the bracket itself. Now omit the back of the car and ride it to check your work.

Advantages of timely replacement

To cope with the replacement of the sleeves in his car will be able to every driver, because this process is not ultra-plated repairs. Everything can be done with your own hands, but if you do not have time or desire, then it is advisable to seek help from specialists. This will protect the racks of the transverse stability stabilizer from premature wear.

Riding on poor-quality road surface will go to the background if you previously installed new sleeves. And in general, installed new sleeves are the lack of difficulties and problems when driving, as well as comfort and safety.

Features of the problem for popular models

As statistics, owners of such car models, like Renault Megan, Skoda Rapid, Volkswagen Polo, Lada Vesta (and other representatives of the domestic auto industry) are faced with problems associated with stabilizer bushings. Consider the features of specific auto models, as well as recommendations when replacing.

Table. Description of the problem for some models

Model	Description of the problem
	Often it is the structure of the suspension this car is the main reason for the problems with the sleeves. Vesta is famous for the larger stabilizer racks, because of what unpleasant sounds may occur when driving. Many car owners underestimate their cars to solve this problem. You can also use special silicone-based lubrication.
	There is one proven way to eliminate squeaks - install a small piece of the old timing belt between the stabilizer sleeve and the car body. The replacement of the sleeves is no different from the indicated in the instructions above.
	As practice shows, it is best to get rid of creaks to install the original VAG gum. Also, many motorists use repair bushings, which differ from ordinary sizes (repaired less than 1 mm). Alternatively, you can set elastic bands from other models of this manufacturer, for example, from Skoda Fabia.
	The process of replacing the sleeve is no different from other models, but before installing a new gum, it and the landing place must be treated with lubricant, which then will not harm it in detail. For this purpose, you can use shampoo or soap. Depending on the modification, Renault Megan can be equipped with a reinforced or conventional suspension, therefore, the dimensions of the bushings and the stabilizer itself may differ. Consider this when buying parts for replacement.
	Before purchasing bushings, it is necessary to first extinct the diameter of the stabilizer, since their dimensions may differ depending on the modification. To do this, use a caliper. Many specialists recommend buying special gum for their cars equipped with anthers to protect against dust and water. To process the surface of the parts, it is necessary to use silicone-based tools that will not destroy the rubber. Such means refers to "Molykote PG-54", "Litol-24" and others.

As a conclusion

Despite the simplicity of replacement, almost every motorist can cope with, it is impossible to forget about security. Vehicle weight is not comic, so wrong use The jack or the lack of an anti-tart wedge can lead to serious injury. So that this is not, be sure to check the serviceability of the jack, and all the steps this process Perform with extreme caution.

Transverse stability stabilizer is an interesting thing. His main feature is a frequent underestimation by car enthusiasts, especially those who, behind the wheel, recently, or nothing cooler "nines" with emerged shock absorbers did not see. Indeed, it can be removed at all and throw it out - the car will still ride. True, bad.

What are the sleeves and why they need

The main task of the sleeves is a decrease in the noise of the suspension when moving and fastening the stabilizer to the car body.

Design features Stabilizer

In the field of mechanical engineering, the stabilizer appeared together with the first cars, the maximum speed of which exceeded the mark of 20 km / h. Due to the larger rolls arising from turning, there was a need to install this component. The main goal of the stabilizer is to protect the vehicle from tipping, because during turning the external wheels increases, and the internal, on the contrary, is reduced.

On a note! All auto pendants are equipped with a stabilizer, not only in front, but also from behind. The stabilizer is not needed only if a torsion beam is installed in the back of the vehicle: the functions of the stabilizer will be naked on the suspension itself.

The design of the stabilizer of many cars is a P-shaped metal rod, made of spring steel. For fastening the device to the body, special clamps and sleeves are used, allowing the stabilizer to rotate. For greater stability of the car and increase the elasticity of the stabilizer, bushings are used - all shots from various suspension elements come on them.

Stabilizer bushings. Signs of malfunction. Effects.

For the best damage to vibration and power influences going on the car body, the overwhelming majority of the suspension elements are connected by elastic elements. The same applies to the stabilizer. For its attachment, special sleeves (gum, pillows) are used from durable rubber or polyurethane. Over time, as the vehicle is used, the bushings can begin to collapse and noticeably lose in elasticity. The result of this becomes unsatisfactory work of the stabilizer \u003d. More serious defects can begin to begin to appear, which will eventually increase over time.

The first symptom that foreshadows the replacement of the sleeves will become a slight stall of the suspension. A similar knock can be observed at the "tired" shock absorbers. Only here in the case of the sleeves he can hear not only on the pits and ughab, but also when entering relatively cool turns. At the same time, the car is often felt excessive and sluggish. The appearance of the knock will be a consequence of the ariser in the connecting nodes of the stabilizer levers due to the wear sleeves.

If there are no measures on time, then the knocks in the future will only increase and will begin throughout the suspension work due to the increasing deformation and the destruction of the sleeves. A transverse bunch of body pitching and an excessive backlash booster can appear. Perhaps the "digging" of the car is not only in turns, but also in cases of braking or rebuilding. Automakers are mostly advised to change the stabilizer bushings every 30-40 thousand runs. However, in our conditions, it is still better to focus on wear sleeves. So suddenly the knock and light rattle in turns will be explicit signs Near the replacement of components.

As a popular method of checking the sleeves in health, it is proposed to move on the 2nd gear of the "lying policeman" by the geography. A deaf knock appeared in the pedal area - most likely, the bushings of Khan. You can also just climb everything for the car itself. The worn sleeve will "delight" the presence of cracks and sweetes characteristic of worn and cramped rubber. This cracks are sometimes called "daisies" sometimes called these cracks.

Also, the rubber bushings can simply cry and lose the necessary elasticity. If the bushings of the stabilizer fails to be considered, then just swing up and down and down and down the stabilizer itself. If the backlash, violets and knocks are felt at the bottom of the suspension, it means that the sleeves came into disrepair.

But for best result It is better, of course, to call on the flight, the observation pit or take advantage of the lift. From the tools you will need only a lomik or an assembly blade that you just stop the machine in the bottom and slightly "sharing" the stabilizer, in the places of its docking with the body. If a noticeable backlash was felt or a loss of elasticity was found, then it's time to think about replacing the sleeves.

List of necessary tools

You will certainly need to have the following set of tools: new sleeves; To drench the subframe bolt, a horn key of 24 is required; keys at 17 and 15; To drench the screws from the protection of the motor - the key to 10; For fastening bolts - key to 13; Clamps made of metallic material by 20 - for clamping stabilizers, since old to be replaced; Means for processing from scale and rust - WD 40; graphite lubrication; jack.

Advantages of timely replacement

To cope with the replacement of the sleeves in his car will be able to every driver, because this process is not ultra-plated repairs. Everything can be done with your own hands, but if you do not have time or desire, then it is advisable to seek help from specialists. This will protect the racks of the transverse stability stabilizer from premature wear.

Riding on poor-quality road surface will go to the background if you previously installed new sleeves. And in general, installed new sleeves are the lack of difficulties and problems when driving, as well as comfort and safety.

Replacing the sleeve of the stabilizer "KIA"

Replacing the bushings of the KIA stabilizer provisions the following algorithm: lift the front of the car and dismantle the wheels. Find the steering shaft and apply a mark (for easy further installation to the original place), turn the fastening bolt. Using the jack, lift the gearbox, unscrew the rear pillow and the subframe. To simplify access to rear pillows Four bolts are twisted, with the help of which the subframe is attached. Raise with a jack front of the subframe. Fastening to remove and treat with oil solution to prevent the development of corrosion processes on the metal. Screw them in your place only by four or five revolutions.

It is made cross to ensure additional reliability and uniform tightening of the plane. Loosen the jack to the level at which it is possible to reach the bushings bolts. Schill S. right side It can be easily unscrewed through the boost space, and on the left side - from the bottom. Put the brackets. This procedure is carried out with a neat way, so as not to cause damage to the claw on the steering boot. The process is repeated in reverse order. Features of the car "Kia LED" in the fact that the steering tree has a telescopic look, and therefore installing it occurs at the last moment.

There are the following types of bushings:

1. Spherical (or "iron") sleeve. According to the design resembles a ball support;

2. Rubber sleeve.

To date, becoming increasingly popular Polyurethane stabilizer bushings. They are pretty simple in replacement, which is an important plus, and also have them good characteristics For operation. Experienced drivers They may safely say that it is such details that are most convenient.

If a there was a malfunction in the stabilizer bushings, it must be replaced in obligatory. Otherwise, it can be very bad to reflect on the go and handling of the vehicle. When the sleeve was deformed, or cracks appeared on it, some noises may appear in the automotive suspension area (mainly when the car runs on the obstacle, or increases speed). In principle, the challenges in the field of suspension are precisely such noises.

For, to make sure that it is necessary to replace the sleeves,periodically, it is necessary to diagnose the suspension, after which a malfunction will be detected or preventing it.

In the case when it was revealed that it is necessary to replace the stabilizer bushings, This can be done independently. Moreover, there is nothing complicated and this is quite simple. Initially, bolts are unscrewed, with which the clamp is attached. Then the stabilizer is assigned to the side and the old details are removed. Well, for final action, a new item is very neatly installed.

It is according to such a scheme replaced as front stabilizerand rear. After replacing the spare parts, riding the car will be much more pleasant and comfortable, and various kinds of road obstacles will be overcome without any difficulty. Among other things, the performance of racks will increase with new elements.

Stabilizers are responsible for the resistance of the car on the road. To eliminate noise and vibration, from work component parts Stabilizers, special sleeves are used - elastic elements that give smoothness.

What is a sleeve? Elastic item is created by casting from rubber or polyurethane. Its form is practically not changed for various models of machines, but sometimes has some features depending on the design of the stabilizer. To raise performance features Sleepings, sometimes they have tides and grooves. They enhance the design and allow the details to last longer, as well as protect against mechanical impact capable of damaging them.

When is the transverse stabilizer bushings are replaced?

It is possible to determine the degree of wear of the bushings in prophylactic inspection. Cracks, changing the properties of rubber, the appearance of scuffs - All this suggests that you need to change the detail. Usually replacing the bushings every 30,000 km Run. Experienced owners advise you to change all the sleeves at once, regardless of their external state.

During preventive inspection The bushings can be contaminated. Should be cleared of them from dirt so as not to provoke accelerated wear Details.

An unscheduled replacement of the sleeves is needed when the following signs are manifested:

• right steering wheel during the entry of the car in turns;
• tangible steering wheel beating;
• kruz roll, accompanied by characteristic sounds of sounds (clicks, violins);
• vibration in the suspension of a car accompanied by outsiders;
• with rectilinear movement, the car takes to the side;
• total instability.

Detection of such problems requires urgent diagnostics. Primary attention should be paid to the bushing. Replacing them, you can check the operation of the car, and if there are signs of a malfunction, an additional inspection should be carried out.

Replacing the front stabilizer bushings

Regardless of the car model, the overall order of replacement of the bushings is preserved. Only tools and some details of the procedure are changing. Guess what exactly needs to be done as an additional action, even a newcomer driver will be able.

Front stabilizer bushing

For it is necessary to follow the following items:

1. Install the car in a fixed state on the pit or lift.
2. Using the tools, weaken the bolts of the wheels in front.
3. Fully remove the wheels of the car.
4. Unscrew the nuts attaching racks to the stabilizer.
5. Disconnect racks and stabilizer.
6. Loosen the rear bolts of fastening the bracket, framing the sleeve, and unscrew the front.
7. Using sweater tools, get rid of dirt in a place where new sleeves will be installed.
8. Using silicone spray or soap solution, carefully lubricate the bushings from the inside.
9. Install bushings and make a number of procedures reverse listed to return the car into the working condition.

To install new sleeves on some car models, you may need to remove the crankcase. This will facilitate the replacement process.

Replacing the rear stabilizer bushings is carried out similarly. The only thing to remove the front sleeves is sometimes more difficult due to the complexity of the design of the car in front. If the driver managed to change the front sleeves, then it will certainly cope with the rear sleeve replacement.

Often, the reason for replacing the sleeves is the occurrence of their screens. This factor is although not critical, still delivers the inconvenience to many drivers and passengers.

Skyrplay bushings stabilizer

Causes of squeaks

Often owners passenger cars Complaints on the script of the stabilizer bushings. Often it occurs when frosts or dry weather. However, the conditions for the occurrence are manifested individually. The main reasons for the emergence of this problem is:

• low quality material from which the stabilizer bushings are made;
• the rejection of rubber on the frost, because of which it becomes inelastic and makes a creak;
• significant wear of the sleeve or the output of it;
• features of the design of the car (for example, Lada Vesta).

Methods for solving the problem

Some owners of cars are trying to lubricate the bushings in various lubricant materials (including). However, as practice shows, it gives only temporary effect (And in some cases it does not help at all). Any grease attracts dirt and trash to itself, thus forming abrasive. And this leads to a decrease in the resource of the bushings and the stabilizer itself. Therefore, we do not recommend that you use any lubricants..

In addition, the lubricity of the bushings is not recommended and due to the fact that the principle of their work is violated. After all, they are intended for tight retention of the stabilizer. Being in the essence of the torsion, it works for a twist, creating the resistance of the car roll on the corners. Therefore, it should be securely fixed in the sleeve. And if there is a lubricant, it becomes impossible, because it can also now scroll, making the script again.

The recommendations of most automakers regarding this defect is to replace bushlock. So, the general advice for car owners who have encountered a symbol from the stabilizer, to ride a certain time (one to two weeks enough). If the sleeves do not "proverb" (especially for new sleeves), it will be necessary to replace them.

In some cases helps replacing rubber sleeves on polyurethane. However, it depends on the machine and the manufacturer of the bushings. Therefore, the responsibility for the decision to establish polyurethane bushing lies exclusively on the car owner.

The replacement of the stabilizer bushings must be carried out every 20-30 thousand mileage kilometers. We look for a specific value in the manual to your car.

Some car owners to solve the problem are watched part of the stabilizer, which is inserted into the sleeve, tape, fine rubber (for example, a piece of bicycle chamber) or a cloth. Original bushings (for example, Mitsubishi) have inside fabric insert. Such a solution will allow you to more tightly "plant" the stabilizer in the sleeve and will relieve the car owner from unpleasant sounds.

Description Problems for specific cars

According to statistics, most often the owners of the following cars are faced with the problem of the screenshot of the stabilizer: Lada Vesta, Volkswagen Polo, Skoda Rapid, Renault Megan. We describe their features and replacement process:

• Lada Vesta. The reason for the screenshot of the stabilizer bushings on this machine is feature of the structure of the suspension. The fact is that the Vesta has a stabilizer racks more than the previous VAZ models. They have racks attached to the levers, and the Vesti is attached to shock absorbers. Therefore, before the stabilizer was less coiled, and was not the cause of unpleasant sounds. In addition, Vesta has a large suspension, which is why the stabilizer turns stronger. The output from this situation is two - to shorten the move of the suspension (to undertake the landing of the machine), or use the special lubricant (manufacturer's recommendation). It is better to use lubricant for these purposes, resistant to washing, based on silicone. It is impossible to use lubricants that are aggressive with respect to rubber (also do not use WD-40).

Replacing the stabilizer bushings on Volkswagen Polo

• Volkswagen Polo.. Replacing the stabilizer bushings does not represent difficulties. To do this, remove the wheel and install the machine on the support (for example, a wooden design or jack) to remove the voltage from the stabilizer. To dismantle the bushing, unscrew the two bolts on the 13, which secure the mounting bracket of the sleeve, after which we take it out and get the sleeve itself. The assembly is made in the reverse order.

Another common way that allows you to get rid of squeaks in the bushings of Volkswagen Polo, is that a piece of the old timing belt between the body and sleeve is. In this case, the belt teeth should be directed towards the sleeve. At the same time, it is necessary to make small reserves in the area from all sides. This procedure is performed for all sleeves. Original solution problem - installation of bushings from Toyota Camry.

The main task of the suspension is to ensure an elastic connection between the body and wheels. Thus, the suspension softens the shocks and jumps that occur when the car is moving along an uneven road or its absence. The smoothness of the car's stroke directly depends on the suspension.

The suspension serves as a peculiar shock absorber, absorbing energy that occurs when driving on unevenness, or ingressing in pits and pivots. However, it does not guarantee the complete softness of the movement and is strongly wearing at a frequent movement by irregularities.

Pendants are divided into the following types:

• McPherson;
• duplex;
• multi-type;
• adaptive;
• "De Dion";
• rear dependent;
• rear semi-dependent;
• pickups and SUVs;
• trucks.

McPherson type suspension

McPherson type suspension is one of the oldest. Was developed by a talented engineer Erl MacPherson in 1960. It consists of a transverse stability stabilizer, lever and block. A serious disadvantage of the suspension is the change in the corner of the wheels, but it is very popular due to availability and reliability.

Double suspension

A two-way suspension is one of the most advanced designs. This is a suspension with two levers of different lengths (top short and lower long). This design allows the car to keep stability on the road and ensures the durability of the tires. Each wheel takes its obstacle independently and does not reck out the load on other wheels.

The multi-dimensional suspension was developed not so long ago and is an even more advanced design. It is a set of multiple levers, silent blocks and hinges. All of these components are designed to guess blows and strong shocks while driving. The noise level from the wheel in the cabin also decreases. The suspension has separate transverse and longitudinal adjustments. Wheels are independent of each other. The design is ideal for all-wheel drive cars.

The cost of a multi-section suspension remained quite high for some time, but now even the drivers of the golf class car can afford it.

Adaptive suspension

Adaptive suspension is very curious in terms of design. For a long time, I was primitive and weighed a lot, but now it was very modernized. Due to this, it allows the maximum body roll and wave rack at high speed and allows you to automatically adapt to any type of road coating. The adaptive suspension includes: adjustable transverse stability stabilizers, active shock absorbers racks, control unit chassis and electronic sensors fixing road irregularities and other parameters.

"De Dion"

"De Dion" is named so in honor of its Creator-Frenchman. The main function of such suspension is to reduce the load on the rear axle of the car by separating the crankcase. the main transfer. Carter in this case holds on the body. This design allows you to make a suspension dependent or independent. But there are disadvantages. With a sharp start, the car body can be very pressing on the rear axle.

Rear dependent suspension

Rear dependent suspension - This is a real classic option, as it was used on many old VAZ cars. The suspension is based on cylindrical screw springs, which are elastic elements. The beam of the rear axle "hangs" on the springs and is fixed to the body by four longitudinal levers. The reactive transverse rod performs the role of the rolls of rolls and has a positive effect on handling. But the comfort and smoothness of the move from this suspension do not wait, as the rear axle weighs a lot.

Half-dependent rear suspension is most often used in cars with fully drive. Its basic elements are two longitudinal leverage, fitting in the center of the cross. Such suspension weighs a bit and does not require any special maintenance and serious repair. But on the rear-wheel drive cars such a suspension cannot be installed.

Other types of suspension

The suspension of trucks is most often dependent with transverse or longitudinal springs and hydraulic shock absorbers. This design allows you to simplify the process of production and repair of trucks.

Transverse Stability Stabilizer: Design and Purpose

Stabilizer of transverse stability - an indispensable part of the suspension. It provides a reduction in the rhombus of the body when turning, an increase in the clutch of the wheels with the road surface and the uniform distribution of the load on the frame. The form resembles a metal beam with curved tips. Each side is attached to the wheels of one of the axes, most often in the front (front stabilizer). Also, this design element is attached to the car body.

Suspension diagnostics in the service center

The cost of such a diagnosis varies from five hundred and thousand rubles. Diagnostics allows you to identify the suspension defects. Since this part of the car is most susceptible to wear, then the diagnostics should be carried out quickly and timely.

Determine that the time has come to check the suspension for goodness, you can on an uncharacteristic knock and an increase in the braking car. The stability of the car on the road over time also weakens. Diagnostics in service centers are performed using high-precision equipment (a luftomer, lateral care tester) and provides maximum informativeness. After the diagnosis, you will receive a special diagnostic card with the results of work.

Special sleeves are used to set the stabilizer. What is the sleeve? These are elastic elements providing a car smoothness. These bushings also provide noise and vibration from the stabilizer.

The bushing is created by casting from rubber or polyurethane. The form for most models is identical. Additionally, equipped with grooves protecting from mechanical exposure.

Signs of wear of the stabilizer bushings

There are several signs:

Causes of fault of the sleeve

The bushings most often fail due to poor road surface, the use of various reagents. Reagents that are used during the ice are no exception. Aggressive driving style with sharp braking and start quickly leads to the wear of most of the designs of the car, including the stabilizer bushings.

Low temperatures may be a serious cause of wear. Rubber of poor-quality sleeves will hard and lose the necessary elasticity.

And finally, the most serious factor of wear is the time. Stabilizer bushing, like most elements of the car design, is a spare part of shelf life. Any sleeve is sooner or late to wear and requires replacement.

Before replacing the stabilizer bushings, it is necessary to thoroughly inspect the suspension. The suspension must be cleaned of dirt. You can determine the wear of the sleeve visually: it will be patterned cracks and various sweetes. Rubber of wear sleeves loses elasticity. For inspection of the sleeves, a special observation pit or an elevator will help you. If there are no such amenities - take advantage of the "folk" way. Hands up in the top of the roof of the car and shake it. The knocks and creak at the bottom of the case will be a signal to replace the sleeves.

Some car owners are trying to extend the durability of the sleeves using special lubricants. This method It is not recommended because the lubricant in the process of motion "collects" various road trash and dust. But if you still decided to take advantage of the lubricant, then buy a quality product that does not destroy the rubber. You are suitable "Litol-24" and "Molykote CU-7439". These are universal products. They can be used even for lubrication brake calipers. Lubricant sleeves are often available in the repair kit. In some cases, you may need a scrap.

To replace the sleeves you will need one or more jacks. It is advisable to replace on observation pitwhere special supports may also be needed. From the tools will need wrench, screwdriver and repair kit.

Step-by-step instructions for self-replacement

The process of replacing the front and transverse stabilizer Some are different.

To replace the front stabilizer bushings, you need to make a number of actions described below:

1. Install the car still above the observation pit or on the lifting.
2. Using tools Loosen the wheel bolts that are in front.
3. Remove the wheels.
4. Unscrew the mounting nuts to the stabilizer.
5. Disconnect the rack and stabilizer.
6. Loosen the rear brackets fastening bolts that frames the sleeve, and then unscrew the front bolts.
7. Clean the place to install new sleeves from the mud.
8. Lubricate inside Sleepings with a silicone spray or soap solution. To do this, it may also be suitable for a special lubricant available in the remnabilities.
9. Set the stabilizer bushings and reverse the installation of all parts.

To replace the cross stabilizer bushings, you also need to install the car stationary over the pit or on the lift. After that, make a number of actions described below:

1. Place the anti-collective shoes for the rear wheels of the car and slightly raise the front.
2. Special horny key, unscrew the nuts on the brackets in places where they are attached to the bottom lever of the car suspension. Spend this operation on both sides of the stabilizer bar. Hoters-grovers under nuts are removed manually.
3. Remove the brackets and remove worn sleeves. To do this, beat the stabilizer bar scrap and hold it with the same scrap when removing the sleeve.
4. If there are central sleeves, you will have to remove the stabilizer bar, which is fixed on two brackets. Nuts on them can be unscrewed by a wheelchair key.
5. After removing the bar, clamp the bracket in vice. Then you can remove the bar, and then the sleeve.
6. Replace the bushings, clearing the place of installation from dirt and having lubricated.
7. Further, as usual, reverse installation is carried out.
