How much is the repair and replacement of the rear bridge of the VAZ 2106

In 90% of cases of appeal to the car service with the problems of the rear axle and, in particular, the gearbox of classical zhiguli, the owners receive a refusal. Maximum that most experts can offer - buy a new VAZ reducer. The reason for this is one - elementary technical ignorance, because only units can correctly diagnose and adjust the rear gearbox of the classics. The new gearbox can be bought for 6-7 thousand, it will be a corporate factory mechanism, from disassembly, the price of the unit will be about 3 thousand, and on the hands or on the market the gearbox with traces of long-term use will cost about 2000 rubles.

It is easier to sell a new one to adjust or restore the old one, especially for this you need certain knowledge, and it is as much as expected qualified adjustment. Therefore, we decided to theoretically cut the owners of classical zhiguli so that in the case of which you could confidently remove, adjust, repair and install a full-fledged worker unit. But for a start a few words about the gearbox device.

Rear bridge reducer VAZ 2106. Device

The rear axle reducer in all classic VAZ models is installed in the rear axle crankcase and consists of two main nodes:

• conical main transmission of hypoid type;
• inter-wheel differential.

The differential has the same design on all rear-wheel drive vehicles, with the exception of all-wheel drive Niva. There is sometimes a self-locking differential. But on the six, he has nothing, so we will leave it yet alone.

The main transmission of hypoid type is made in the form of a two-axis gear - leading and slave. The drive gear is rigidly connected with the car's cardan shaft, installed on the shaft on the bearings pressed into the carcarete. The lead gear shaft is associated with the flange of the cardan fastening with a slotted compound and is completed with a nut, which is regulated by the backlash bearings, but a little later. The driven gear is fixed on the differential crankcase, together with it and rotates on the bearings. They are fixed with the help of adjusting nuts, which are regulated by the gap between the teeth in the engagement of the main transmission. The rotation on the semi-axis is transmitted by means of conical gears, which are engaged in engagement with the satellite satellite gears. A little confusing, but if you look at the scheme, everything will immediately become clearer.

Hypoid transmission and magic numbers of the Redukers VAZ

Technologically, the easiest way to transmit rotation from one conical gear to another when they are on the same axis. But in rear-wheel drive gearboxes, the transfer with shifted by 31.8 mm axes is applied. Such a complication of the design is caused by the fact that, together with the transverse slippage of teeth, the hypoid transmission makes the teeth slipping and longitudinally.

And this, in turn, gave the following advantages:

• long service life gears;
• silent work;
• fast trigger of teeth;
• increased ground clearance.

Both gears of the main transfer with strong wear or damage change only in pairs. The fact is that when preparing for the sending of finished parts of spare parts, the pairs are selected on special accurate equipment, taking into account the tolerance, the correction of which is applied to the shaft of the leading gear. On the driven gear, you can read all the necessary information about the gearbox model - the gear ratio (on the VAZ 2106 it is 11/43), model 2106, serial number and release date.

In principle, in the gearbox of any model of the Zhiguli, one of the four sets of the main transmission gears can be installed. They differ only in the number of teeth, and this dictates a gear ratio. Do not speak, what value is this parameter when choosing a gearbox. It affects both the maximum speed of the car and the realization of the engine torque. As garage tuningers say, "or better pulls, or is going faster." Something they are right.

Nevertheless, as we have already mentioned, there are only four options for pairs of the main transfer:

• VAZ 2101 - 43/10 with a gear ratio of 4.3;
• VAZ 2102 - 40/9, the most direct reducer with a gear ratio of 4.44;
• VAZ 2103 - 41/10, this is the most running average balanced variant of the gear ratio - 4.1;
• VAZ 2106 - 43/11, is the most high-speed gearbox, especially in a pair with a five-speed box, and the number of it is 3.9.

This set gives the owners of the classics limitless possibilities for setting up the dynamic characteristics of the car. No "tuning" is not able to change the dynamics of classics as the rear axle gearbox.

So, for certain purposes you can buy a certain reducer, while the maximum vehicle speed will change, the dynamics of acceleration, fuel consumption, traction force. The most "cargo" gearbox from 2102, a penny in the body of a wagon. His maximum speed is low, about 145 km / h, but the car confidently fines quite serious cargoes and trailers without engine overload. It is necessary to know the measure, but the fact remains a fact. If you need a small tractor in the body of the Zhiguli, for this existence gearbox 2102 with a gear ratio of 4.44 and the number of teeth 40/9. This gearbox has become rare, but if desired, the main pair can be found both new and used. Another extreme is the Reducer VAZ 2106. He will give a car high maximum speed, but there will be no place from breaking, because the traction effort is less than that of twos.

Malfunctions and repair of the Reducer VAZ 2106

Made by technology and a qualitatively adjusted gearbox can serve as decades, not recalling about himself at all. Neither the noise nor the river nor the ringing. So it was until recently, two sought-after goods appeared on the market - fake transmission oil, and in a few years fake rear vase gearboxes. In most cases, all that is sold in auto shops and externally resembles a gearbox, in fact, just a pile of metal, unsuitable for use. The fact is that for high-quality adjustment of the gearbox, which is necessary, we need serious skills and cunning measuring equipment. Here, there can be no need for an adjustment to the eye and speech. And the majority of a hundred people do this, without giving themselves the report that they simply kill a healthy gearbox. After replacing, check the performance of such an aggregate can only on the go. Therefore, they are laundered, painted beautiful paint and put on the shelves of shops next to counterfeit lubricant. We will talk about lubricant separately, and now a little about the main malfunctions of the Reducer of the VAZ 2106.

As in all units that have a closed lubricated volume, the gear of the shank can flow into the gearbox. It is noticeable immediately, because after the parking lot of transmission droplets under the rear axle will be eloquently talking about it. It may also be that in the flows of the oil is not to blame the gland, but weakened the bolts of the reducer of the gearbox to the carder of the rear axle. But the most common symptom of the gearbox is noise. It may not be able to make noise the unit in different ways in different modes, so there will be no specific recommendations without listening to him personally. Nevertheless, there are the most common noise manifestations, which we briefly tell.

The main source of noise is a worn main pair. This sound does not confuse with anything, but it appears under the load. It is worth throwing gas, the noise disappears, and the active phase occurs again after pressing the gas pedal. This malfunction is treated only by replacing the main pair. Fans of experiments can add magic additives into lubricant, but, as a rule, these dubious funds do not restore the main pair, do not know how to regulate the gaps, do not change the bearings.

The noise of the gearbox bearings is pretty simple. They are buzzing under any load, and in the most running cases at low speeds can even hurt.

In addition to replacing no malfunction options. Except in cases where the cause of noise was the wrong tightening of the shank nut after replacing the gland. Improper adjustment of the gearbox can also cause the roast, but it is almost impossible to describe this noise, because each gearbox is manifested in different ways. Adjusting the engagement is carried out only if there are measuring instruments, the dynamometric keys, the necessary probes and most importantly, experience in this matter. Incorrect adjustment to spoil a good gearbox can be literally thousands of kilometers.

Another source of noise from the gearbox is the weakening of the shank tightening nut. It appears due to the fact that the spacer sleeve sends, the backlash in the bearing is increasing, the nut is disliked. The reason is an insufficient moment of tightening nut when replacing the gland or the disgusting quality of the rolling sleeve. In order for the reducer to serve for a long time and fun, only certified transmission lubricants need to be pouring into it, it is preferably those that pointed out AvtoVAZ, observing the frequency of replacement of 10-15 thousand kilometers.
