The wheel bearing ensures uniform rotation of the wheel around its own axis. Of all the elements of the car's chassis, it is the first to meet and distribute shock loads, so the main requirements for this part are strength and durability.
In this article we will talk about what a rear wheel bearing is on a VAZ-2108. We will look at the design of this device, its dimensions, and also understand the process of replacing it.
Design Features
The rear hubs of the V8 are equipped with sealed angular contact ball bearings. Each of them has two rows of balls. This makes the structure as resistant to loads as possible, and also allows them to be distributed with the greatest efficiency.
The rear wheel bearing of the VAZ-2108 is made of heavy-duty steel. Its service life, declared by the manufacturer, is 90-120 thousand kilometers. By the way, these are not empty statements. Oddly enough, VAZ wheel bearings actually last a very long time and, if used correctly, can last twice as long as the stated mileage.
Main characteristics and varieties
The rear wheel bearing on the VAZ-2108 is produced under catalog number 256706. It has the following technical characteristics:
- weight, g – 400;
- number of balls, pcs. – 28;
- ball diameter, mm – 9.525;
- static load capacity, KN – 25.9;
- dynamic load capacity, KN – 30.1;
- rated rotation speed, rpm – 6500.
The VAZ-2108 rear wheel bearing number may be different. If a store offers you a product marked 537906, don’t be surprised. This is a high-load bearing. Some of its characteristics differ from the characteristics of the standard spare part:
- weight, g – 511;
- static load capacity, KN – 90.1;
- dynamic load capacity, KN – 64.8;
- rated rotation speed, rpm – 5000.
As you can see, the reinforced rear hub bearing on the VAZ-2108 has increased resistance to loads. But at the same time, its rotation frequency should not exceed 5 thousand rpm. Such products, when properly used, can “walk” freely up to two hundred thousand kilometers.
Diameter and number of balls
The rolling elements of this bearing are placed through a special groove. Balls with a diameter of 9.525 mm are used as moving elements of the product. In the space between the clips they are placed in two rows, the total number per unit is 28 pcs.
The balls are held at specified positions using a separator. Its task is to position the rolling elements, but not to interfere with their free rotation.
There are ball bearings 256706 with a cage made of steel (without additional designation) and plastic materials: textolite (E, E1, E2) and polyamide (E9).
These features significantly affect the characteristics of a particular product, and therefore, before buying a replacement, you should learn more about the pros and cons of a particular separator.
Important! The use of composite materials for the manufacture of wheel bearing cages can significantly reduce their weight without compromising consumer characteristics. In addition, if such parts fail, they do not create solid debris that can aggravate the situation.
Rear wheel bearing VAZ-2108: dimensions
As for the size of the wheel bearing, they are the same for both modifications:
- outer diameter, mm – 60;
- internal diameter, mm – 30;
- width, mm – 37.
If you are offered a rear wheel bearing for a VAZ-2108, the dimensions of which do not correspond to those specified, it is better to refuse this purchase. All the above parameters are provided for by GOST 520-2002. Foreign analogues of spare parts are manufactured in accordance with the requirements of ISO 15:1998 and have the same dimensions.
Bearing 256706
An angular contact ball bearing with the GOST number 256706 cannot be called a part of wide application.
This is a wheel bearing specially designed for a number of domestic cars. Despite the fact that this is a rather specific spare part, there is a complete imported analogue of this product. Its ISO marking is BA2B633313C.

How to understand that it is time to change the wheel bearing
A failed VAZ-2108 rear wheel bearing may indicate a malfunction:
- the appearance of a characteristic hum from the wheel;
- uneven rotation of the wheel;
- backlash formation.
If you notice that there is a hum coming from one or both rear wheels, rush to diagnose the wheel bearings. You can do this right in your garage. Simply jack up the rear wheel and turn it by hand. It should rotate easily and evenly without making any sounds. Next, grab it with both hands and try to shake it from side to side in a horizontal direction. If the wheel rotates unevenly and you feel play when it becomes loose, get ready for repairs.
Features of choice
When buying a rear wheel bearing for a VAZ-2108, pay attention to the manufacturer. Currently, more or less high-quality domestic parts are produced by the following enterprises:
- SPZ (Saratov Bearing Plant);
- SPZ-4 (Samara);
- VBF (GPZ-23, Vologda);
- GPZ-20 (Kursk).
It is believed that the best domestic manufacturer of bearings is the Saratov plant. His products are very reliable, but not very expensive. Thus, a rear wheel bearing for a VAZ-2108 manufactured by SPZ costs between 400-450 rubles.
Popular manufacturers
The best manufacturer of ball bearings 256706 by domestic standards is considered to be 23 GPZ (VBF), the products of Saratov SPZ are somewhat worse, but cheaper. Cheap, but also unreliable products with the SPZ-4 mark are Russian products assembled from Chinese parts.
When choosing an imported replacement for domestic bearings, you should pay attention to SKF or FAG products. These are products of the upper price segment, but of consistently high quality.

What tools will you need?
Before you begin repair work, make sure you have the necessary tools and supplies:
- wheel chocks;
- jack;
- wheel bolt wrench;
- chisel (core);
- some object to fix the position of the car body when jacking up (a stump, several bricks, etc.);
- hammer;
- spacer made of wood (block);
- head at “30” with an extended handle;
- key to "7";
- vice;
- a piece of pipe for the outer diameter of the bearing;
- long nose pliers;
- special puller for the hub;
- special pliers for retaining rings;
- anti-rust liquid.
If you decide to change the rear wheel bearing on a VAZ-2108, also replace the hub nut. At least that's what the car manufacturer recommends. The fact is that the nut has a special edge that bends during installation and gets knocked down during disassembly.
What do we need?
As a tool we will need:
- The most common jack for lifting car wheels;
- Wooden beam;
- Balloon wrench;
- Special puller for the hub;
- Pliers (useful for removing retaining rings) or a special puller;
- Socket wrench (“30”);
- Socket wrench (“12”);
- Hammer.
Since the tightening torque of the main nut is serious, it is advisable to prepare a pipe as an extension for the socket wrench. A pry bar and chisel may come in handy. Well, it would be a good idea to invite a partner - to support, help and chat.

Changing the rear wheel bearing with your own hands
Replacement of the VAZ-2108 rear wheel bearing is carried out in the following order:
- We install the car on a flat surface, fix the front wheels by placing wheel chocks under them.
- Remove the cap covering the hub nut.
- Using a chisel (core), we bend the bent edge of the hub nut so that it does not interfere with its unscrewing.
- Using a 30mm socket with an extended handle, unscrew the nut. If it does not give in, treat the threaded connection with anti-rust liquid.
- After unscrewing the nuts, unscrew (not completely) the wheel mounting bolts.
- We lift the body with a jack, fix its position with stumps (bricks), and unscrew the wheel bolts. We dismantle the wheel.
- Using a key set to “7”, unscrew the guide bolts on the drum (2 pcs.).
- We remove the drum. If it is not removable, we treat the place where it fits onto the hub protrusion with a rust-fighting liquid, and then knock it down using a hammer and a wooden spacer.
- Now completely unscrew the hub nut.
- Using a special puller, we dismantle the hub, grasping it with “paws” and rotating the nut. If you do not have such a device, take the removed wheel and screw it to the hub with the back side. Use the wheel as a lever.
- Remove the hub from the axle.
- Using long-nose pliers or special pliers, remove the bearing retaining ring.
- We place the hub in a vice and, using a hammer and a piece of pipe, carefully knock out the bearing.
- When the bearing is knocked out, lubricate the inner surface of the hub with grease.
- We install the new bearing without removing the hub from the vice.
- We place a wooden spacer on top of the bearing and, hitting it with a hammer, hammer the part into the hub until it stops.
- We put the locking ring in place.
- We put the hub with the new bearing on the axle. If she sits down tightly, we help her sit down using a hammer and a spacer.
- Screw on the new hub nut. We tighten it until it stops. The hub should still move inward.
- Install the brake drum and secure it with guide bolts.
- We mount the wheel.
- Remove the jack and tighten the hub nut completely. If you have a torque wrench, observe the tightening torque (186.3-225.6 Nm).
- We bend the edge of the nut, fixing its position.
- We put a cap on the nut.
- We jack up the body, check how the wheel rotates and whether there is any play. It is also recommended to check the operation of the parking brake.
Wheel alignment
After replacing wheel rims, the dimensions and bolt patterns of which differ from those provided for by the design of the VAZ 2110, it is necessary to make all the necessary adjustments in order to ensure reliable protection of the entire chassis, as well as tires and arches.
Correct alignment angles are required for each front wheel. There are three parameters that require correct installation: wheel toe, caster angles of the steering axles, and camber angles of each wheel.
Wheel installation options
The rules by which the parameters of the front wheel are set are as follows:
- You won't go far if everything hangs out the way it wants, and the car is pulled to the side when it should be going straight. To ensure the stability of each front wheel, they are installed strictly at the required angles to the body and suspension elements. This is called the longitudinal inclination angles of the turning axis. Installation dimensions are indicated in the instruction manual;
- Camber is the angle between the plane in which the wheel rotates and the vertical. The camber bolt helps install it (it secures the telescopic strut and steering knuckle). If the camber is installed incorrectly, the car “steals” and the tire tread wears out more on one side;

Reasons for replacing and diagnosing wheel bearing failure
In addition to driving style and road quality, the reasons for wear are the following: - quality of products; - quality of service; — weather conditions (at high temperatures, overheating and expansion occur, and the bearing is also susceptible to drying out of the lubricant). — other minor factors: serviceability of the suspension, tire profile, play in the units, alignment.
Let's look at the signs of a breakdown, there are several of them: 1. Rumble from behind when driving; 2. Vibration in the cabin; 3. Over time, the noise will turn into periodic grinding; 4. The wheel is loose when raised;

After diagnostics, making sure that repairs cannot be avoided, the question of choosing a new spare part will arise. The hub is equipped with a double-row angular contact bearing, number 6-256706E1S17 (marked according to GOST). The price of the bearing varies from 600 to 900 rubles.
It is recommended to purchase bearings from the following manufacturers: - VPZ (see VBF marking) - Russian plant in Vologda; – SPZ – SPZ GROUP – Russian Samara; — GPP — produces high-quality bearing products in Vologda.
To avoid mistakes when purchasing, check the markings and dimensions: - External mounting diameter - 60 mm; — Internal landing diameter – 30 mm; — Height – 37 mm.
How to change the rear wheel bearing on a VAZ? First, let's prepare for repairs
Let's prepare the car, as well as the tools according to the list: - Jack; — A driver or pipe to increase the torsional moment; — Wrench 30, better with a head; — A set of other keys; — Wheel hub puller with claws (to remove the hub); — Vise; — Hammer and chisel; — Round nose pliers; — Torque wrench.
Now familiarize yourself with the design of the hub: 1 – rear axle; 2- hub body; 3- protective casing; 4 – lock pin. ; 5 – bearing; 6 – washer; 7 – nut; 8,9 – protective cap with gasket.
Place the car on a level surface, provide light, and install wheel chocks. Next, we put the first gear, and if desired, the parking brake, now we proceed to operations.
Replacing rear wheel wheel bearings on a VAZ yourself
The rear wheel bearing of the VAZ 2110 is changed according to the instructions, but first consider the following points:
- The bearing cannot be reinstalled.
- It is recommended to replace the second bearing immediately, on the other hand.
We disassemble the hub assembly and dismantle the product
- First, loosen the bolts securing the wheel and the hub nut.
- Next, we jack up the car.
- Now unscrew the bolts and nuts completely and remove the chassis.
- The decorative wheel cap (boot) also needs to be removed.
- Now use a hexagon to unscrew the pins that hold the drum; you don’t need to remove the pads.
A few tips for motorists
- It is quite easy to understand that the front wheel hub of a VAZ 2110 is faulty. While the car is moving, you will hear grinding, humming and knocking noises every now and then.
- To ensure that the wheel alignment remains normal after replacement, perform the replacement without unscrewing the alignment bolts.
- The manufacturer recommends that car owners change the components of the front wheel hub at 55,000 km.
As you have already seen, DIY repairs are easy. Such repairs may have to be done every year, because the roads in the country leave much to be desired. But self-service will cost several times less than if you turn to a service station for the service. If you prepare in advance and do all the work sequentially, taking into account each step, the replacement will not take much time. You do not risk anything, the cost of the part is not that high. But such a simple job involves many nuances that are important to consider.
If the owner of a VAZ 2110 car notices that when the car moves, an incomprehensible knocking or sound is heard in the wheel area, which may simply disappear if the vehicle makes a sharp turn, then this means that an immediate replacement of the front wheel bearing is required. The fact is that the bearing related to the front hub area cannot be repaired, so this part in the VAZ-2110 needs to be replaced as quickly as possible.
Do-it-yourself replacement is quite simple if the car owner has the skills to repair automobiles and has a convenient garage space. This event should be carried out as quickly as possible in order to avoid unpleasant situations when driving a car.
Recommendations for replacement, useful video on repairing the VAZ 2110
1. If you don’t have a torque wrench, then tighten the nut all the way, and then loosen it back 60 degrees. 2. After you have changed the spare part, check how the drum rotates; there should not be the same noise or grinding noise. 3. The time required for work on this side of the car suspension is 2 hours. 4. For safe work, first loosen the wheel and hub fasteners, and only then lift the car. 7. If you have recently developed a hum (play is also allowed), then try tightening the hub nut with a force of up to 23 kgf/m. Perhaps the noise will go away; after tightening, do not forget to lock the lock nut. 6.
