Replacing the front wheel bearing on a VAZ 2109 (21099, 2108) with photos and videos

Bearing 256907

The main area of ​​its implementation is the front wheel bearing of VAZ 2108, 2109, 2110, 2111, 2112 cars. It has the following design features - ball, angular contact, double-row, closed type (seals on both sides). The double row ball bearing has the ability to be locked on both sides. Bearing 256707 is installed in the front hub of the most modern VAZ models (Kalina, Granta).

Since most VAZ models have become widespread not only in our country, but also abroad, the need for front hub bearings is very high - they are created immediately at 4 factories in our country:

• OJSC (form of organization of a public company; joint stock company)
  “Saratov Bearing Plant” (labeled SPZ) - according to professionals, produces the best front wheel bearings in our country, and at the same time they are not very expensive. Purchase from official representatives in your region (only they have a guarantee of authenticity and, at the same time, small trade margins - the cost of a wheel bearing will be about 350 rubles).
• 23 GPZ (or VBF, Vologda) - among motorists it is considered the best plant, but the wheel bearings of the previous manufacturer are in no way inferior to them in durability, are less likely to be counterfeited and are slightly cheaper.
• SPZ-4 (Samara) - produces products for those who are used to saving. But if you need a high-quality front wheel bearing, it is best to focus on the manufacturers presented above.
• 20 GPZ (Kursk) - currently not performed, but some companies still sell them; you will not receive a guarantee of their long-term performance.

For off-road use, it makes sense to install hub roller bearings 537907, which have an increased load capacity, but a lower maximum rotation speed.

Russian bearings are manufactured in accordance with GOST 520-2002, imported from other countries in accordance with ISO 15:1998. According to the international designation system, the number of this bearing is 532066DA.

Technical characteristics and dimensions of the front hub bearing 256907:

Internal diameter (d): 34 mm;

External diameter (D): 64 mm;

Ball diameter: 9.525 mm;

Number of balls: 28 pcs.;

Dynamic load capacity: 31.5 kN;

(Load capacity of the roller bearing of the hub 537907 - 68.6 kN);

Static load capacity: 27.9 kN;

(for a roller wheel bearing this value is 99.8 kN);

Rated speed: 6000 rpm. (for a roller, this value is less)

Engineering Features

The spherical roller 2109 enhances the technical parameters of the roller bearing. The geometry of the inner surface of the outer ring makes it possible to compensate for misalignment. Roller bearings are used under conditions of uneven and significant radial stresses.

Failure to maintain alignment changes the motion of the rolling elements. The quality properties of roller bearings are reduced. The axes of the installation sites certainly require adjustment.

The marking of 2109 bearings is described by GOST 3189. The designation contains numbers and letters. The designation includes the main characteristics of the bearing.

The composition includes outer and small rings. Working media - short or long rollers. Rotating rollers are screwed into cages. Mechanism 2109 is the support of the rotating device.

Basic deviations of roller bearings are designated by the letters lb L. The letter L is used to mark the inner ring. The outer ring of a bearing with accuracy class 6 is designated l6 (el 6). The letter l is used for the outer ring.

The outer surface of the inner ring and the large one inside also have running tracks. During activity, rollers roll in the chutes. Operation involves rolling friction.

Auxiliary design features are present in products with short rollers (rolling bodies). They do not function well enough at high speeds. The design flaw is the inability to absorb axial load. The advantage is high load-bearing capacity.

VAZ 2108 front wheel bearing size

No matter what spare part a modern car needs to be perfectly matched to fit and technological dimensions. Much to our chagrin, the manufacturer does not constantly take into account the individuality of the use of materials in spare parts, which affects their service life, reliability, and, ultimately, safety of movement. The chassis of a car is subject to enormous overloads, so it is simply unacceptable not to pay attention to the correspondence of industrial sizes with the ones being replaced.

VAZ 2108 front wheel bearing size

If we take this issue more specifically, the chassis of cars of popular models and brands most often suffers from low-quality spare parts. First, let's look at this problem using the example of a VAZ 2108 front wheel bearing.

It would seem that there is nothing complicated - the hub has its usual dimensions, which the roller bearing must correspond to:

internal diameter - 34 mm; external diameter - 64 mm; Bearing width - 37 mm.

Only based on these characteristics can you select a bearing, of which Russian factories produce thousands. Manufacturers from China actively help with this, providing products that are not of the best quality and do not stand up to any criticism. Neither the steel grade, nor the number of balls, nor the dynamic characteristics of such bearings correspond to the standards. There are bearings completely unmarked, and there are especially careful owners who purchase them. Such bearings burn out within 1000 km and simply fall apart while driving.

Individual selection of wheel bearings for VAZ 2108

Naturally, we will not be able to check the dynamic load on the bearing races or on any of its balls. But it is necessary to understand, like Our Father, that:

• The VAZ 2108 wheel bearing is marked 25 69 07;
• according to the international marking system it is designated 53 20 66 DA;
• the bearing has a mass of 0.445 kg;
• ball diameter - 9.525 mm;
• number of balls - 28.

The difficulty in choosing bearings lies in the fact that they are not consumable parts, and they are not changed as often as piston rings or silent blocks. That’s why some manufacturers don’t even bother making human packaging. In addition, the bearing used in the front wheel hub of the VAZ 2108 is maintenance-free, which means:

• the bearing does not require lubrication;
• does not require preload;
• does not require adjustments during installation and operation;
• must have a very high resource.

Wheel bearing system for VAZ 2108

All VAZ cars are equipped with only 3 types of wheel bearings - wheel bearings for front-wheel drive VAZ cars, wheel hub bearings for rear wheels, and wheel bearings for Kalina and Granta cars, which differ in their smallest sizes.

All VAZ bearings are of the HUB-1 type, and this type is characterized by the system and the individuality of the installation. The bearing has a double-row system, is a type of angular contact ball bearings with closed working surfaces and does not have flanges for attachment to the hub.

Manufacturers and prices of VAZ wheel bearings

These bearings belong to the middle price sector, therefore the demand for them is very high. Because of this, you can often come across the fakes that we mentioned. However, the transition of the VAZ plant to bearings of this type, instead of roller bearings, the old standard, made it possible to choose bearings not only made in Russia, but also from almost all other foreign factories.

VAZ 2101

If we make a comparison with the wheel products of other VAZ models, then the famous FIAT-124 wheels with a width of 4.5 inches and an offset of 37 mm were used on a penny. They contain eight oval holes.

In 1970-74, AVTOVAZ, then still Soviet, had some difficulties associated with the supply of parts from Fiat, so the 2101 used rims with stampings and 16 round holes.

Protective chrome caps were used for the mounting bolts and the hub bearing on the central part of the rim. The same ones were used on Fiat, however, without indicating the car series on the central part.

For stability, the developers provided special “ears”, and dismantling was carried out due to the springiness of the cap.

The first 2101 models had silver wheels, but over time the line began to use gray-white models with oval-shaped holes.

Bearings VAZ 2109 "Samara"

VAZ-2109 Lada Samara is a 5-door front-wheel drive hatchback manufactured by the Volga Automobile Plant. Produced since 1987. This is actually a 5-door version of the VAZ-2108. In 2004, the creation of the VAZ-2109 was transferred to the AvtoZAZ plant in Ukraine. Previously, the car was equipped with in-line four-cylinder eight-valve petrol carburetor engines with a volume of 1100, 1300, 1500 and 1600 cm3. Since 1994, four-cylinder gasoline engines with broken fuel injection began to be installed on these cars.

Refill containers and recommended operating materials.

Fuel tank - 43 l. AI-93 gasoline; cooling system - 7.8 l antifreeze A-40; engine lubrication system - 3.5 l, gearbox crankcase (5-speed) - 3.3 l, hydraulic brake system - 0.55 l, front suspension struts - 2× 0.25 l, MGP-10; rear springs - 2×0.25 l, MGP-12; windshield washer reservoir - 2.0 l (4 l for cars with cleaners and washers for headlights and rear window), NIISS-4 liquid in a consistency with water.

What Causes Rear Hub Damage?

Replacing the rear wheel hub of a VAZ 2109

Often hubs stop functioning normally if:

• ​ There is some play in the hub bearings, albeit small. That is, they wobble slightly. At the same time, you need to ensure that this backlash does not develop into “Mega backlash”.

Note: If the bearings wobble too much, they can damage other parts located in the vicinity.

• ​ A hum is heard when the bearings operate. Usually, as speed increases, it becomes even more pronounced. After that, when the speed decreases, it does not become any less quiet. Both bearings need to be replaced at once.

Replacing the rear wheel hub on a VAZ 2109

Note: That is, if the hum is heard on only one side, then only one bearing is damaged. But most likely the second one doesn’t have much time left either. And, in addition, buying two bearings in a set will be much cheaper than buying them separately.

• ​ Bearings overheat. This is due to the fact that they begin to spin much faster than usual. This may cause the brake fluid to boil too quickly. Therefore, the braking system will “close up”.
• ​ The wheel bearing is falling apart. Perhaps it is only in the early stages of destruction. It needs to be replaced urgently, as a faulty bearing can cause serious damage.
• ​ The steering tip does not work well.
• ​ There are shortcomings in the operation of the upper or lower ball joint.
• ​ The wheel bearing nut is not tightened properly. Such an oversight can cause backlash. In this case, you can get by by simply screwing in this nut all the way. That is, you should not change the hub or its bearing.

Front wheel bearing VAZ-2108: dimensions, description, photo

According to the car's maintenance card, it is necessary to replace the bearings of the front hubs of the VAZ-2108. Their dimensions are larger than similar ones installed on the VAZ 2101-2107 model. At the same time, there are individualities in carrying out the substitution. The “classic” uses tapered bearings; it is absolutely necessary to observe the permissible force when tightening the hub nut. Otherwise, the bearing will fall apart and you will have to buy a new one. Eights use cylindrical bearings; when tightening the hub nut, you need to apply as much force as you can - just don’t strip the threads.

Analogs and modifications

An excellent replacement for the Russian bearing 256706 will be its imported analogue BA2B633313C. It is important to take into account the country of production of the substitute and the brand. Low-quality Chinese parts are often sold under the same markings.

In some cases, it is worth paying attention to the roller analogue 537906. This product has exactly the same dimensional characteristics, but has a much greater load capacity, although at a significantly lower operating frequency.

Such a replacement is appropriate for older VAZ models that are operated in difficult conditions. This is especially true when driving in rural areas, where load capacity is much more important than speed characteristics.

Signs of a broken wheel bearing

As the vehicle is used, its components and assemblies wear out. In this case, those that suffer the most are those that are constantly loaded - these are rubbing parts. The weight of the motor and the friction force act on the bearing of the front hub of the VAZ-2108. That's why its dimensions are so impressive - to cope with overload. But when an element fails, the following symptoms appear (Symptom from Greek - case, coincidence, sign - one separate sign, frequent manifestation of a disease, pathological condition or disruption of any vital process)

:

1. At early steps there is a barely noticeable rumble.
2. Minor vibrations transmitted from the wheels to the body may be felt.
3. As the bearing wears, the noise and vibration intensify.

If you do not replace it in time, the bearing may jam. During operation, there will be excess heating of the hub - there is very little lubrication inside the bearing race, the iron elements rub against each other.

Structure and types of bearings

There are three types:

The separator in the bearing keeps the rotating parts at the same distance, evenly distributes the load, ensuring quiet and unhindered rotation. The most durable, reliable separators made of metal are also made of polymer.

Bearings are divided into open and closed, the latter being preferable as they are protected from dirt getting inside.

Repair tool

To replace the VAZ-2108 front wheel bearing, you will need a tool. All work must be carried out on a perfectly fixed frame. You will need the following tool:

1. Set of keys and sockets.
2. Mounting blade.
3. Bearing puller.
4. Gas-burner.
5. Jack, wheel chocks and secure supports.
6. A small piece of pipe with a diameter of 10 cm.
7. Hammer and chisel.
8. Pliers for removing retaining rings.

The methodology for carrying out work on the left and right wheels is similar. It is better to replace the bearings on both sides at once. It is necessary to install elements from the 1st and the same manufacturer, which are recommended by the factory.

Selection of spare parts

To replace the bearing, we naturally need the bearing itself and the hub nut.

They can come either as a set or separately. Replacing the bearing is allowed on one wheel, but still, it would be better to change the axles on both wheels. The table below shows the main manufacturers of spare parts, indicating their catalog numbers.

Preparing for repairs

Now it's time to remove the old VAZ-2108 front wheel bearing. Its dimensions are indicated in the article below; when pressing out, you can use a clip from an old roller. Before starting work, do the following:

1. Unlock the front hub nut.
2. Using a 30mm wrench with a huge lever, remove the nut.
3. Place wheel chocks under the rear wheels.
4. Remove the wheel bolts.
5. Raise the side to be repaired with a jack.
6. Install supports under the frame.
7. Remove the wheel and place it under the car engine.

That's all, now you can start dismantling the front wheel bearing of the VAZ-2108. The sizes of the old and new ones must match. If the diameter is slightly larger or smaller, the bearing will not be able to work correctly.

What parameters do factory rims have on a VAZ 2107?

For the seven, 4 bolts were used to attach the disk, and the diameter of the circle of the holes placed was 98 mm. This parameter is specified as PCD 4x98. Thus, the distance between diametrically located holes is 98 mm.

On a note! Drilling a wheel for bolts indicates not only the dimensions, but also the diameter of the disc holes. On the seven, this parameter is 12.5 mm.

Many people do not pay attention to this meaning. However, do not forget that the disc manufacturer calculates the wheel fixation of the hub with maximum accuracy, since with minimal errors, mismatches between the hub and the center of the a/d will lead to runouts.

They, in turn, can cause a tire to burst and cause a serious accident. Therefore, drilling on 2107 is carried out with millimeter accuracy.

On a note! The wheel rim on the VAZ 2107 is made for a hub with a centering hole of 58.5 mm. The hub diameter is designated as DIA 58.5. The bottom line is that large and reliable bolts do not affect the centering of the wheel to the hub. Most often they play the role of fastening elements of the flange and disk.

The centering hole helps orient the wheel product relative to the location of the hub. Therefore, if it does not coincide with the hub, it is recommended to use an adapter connecting ring.

The diameter of the wheel products on the 2107 model ranges from 13 to 15 inches, designated by the letter R. The standard wheel parameters are 13 inches (R13). Below this size is the diameter of the disc rim.

The width of wheels for sevens varies from 5 to 6 inches. As a rule, this parameter does not have the same effect as the diameter of the wheel product.

However, the width will subsequently affect the stability of the tire and wheel of the vehicle. The safety of driving a car depends on this. Full width markings for wheel 2107: 5×13-5.5×13.

Wheel offset is 15-30 mm. It represents the distance between the middle zone of the disc rim and the conjugate plane of that part of contact with the wheel hub.

Removing the front wheel hub

Now you need to remove the hub. To do this you will need:

1. Mark the position of the hub on the strut using a marker. Be sure to thoroughly clean the surface before doing this.
2. Use keys “17” and “19” to unscrew the nuts from the bolts securing the hub to the shock absorber strut.
3. Using a "17" key, you need to unscrew the lower bolts securing the ball joint to the hub. This is a common option when there is no need to replace the ball. But if it is necessary to change it, then you need to unscrew the nut from the ball pin using a “19” key and remove it using a puller.
4. Unscrew the hub nut completely.
5. Carefully knock the front wheel hub off the CV joint.

Important points

As can be seen from the article, replacing wheel bearings is a rather labor-intensive task, even taking into account the fact that the article provides the simplest method (an alternative replacement method allows you to do without removing the steering knuckles, but in this case the car owner will definitely need an inspection hole, which is far from available everyone has). In the method proposed above, a hole is not needed, and the main difficulty is not to disturb the camber of the car’s wheels. If the alignment still turns out to be damaged, there is only one way out: go to the nearest car service center and adjust the alignment again.

Bearing removal

To remove the bearing from the seat, you will need a puller. You can make it even without the help of others, there are no scarce components, the system is very common. The VAZ-2108 front wheel bearing puller is a long bolt with a large thread and a nut. And the most important thing is spacers and mandrels with a diameter similar to that of a wheel bearing. If there is no such puller, then all the work can be done with a hammer, but there still must be a mandrel.

First, remove the hub itself, in which the holes are made for attaching the wheels. Next you need to use pliers to remove the retaining rings. If you don’t have such a tool, you can use a flat-head screwdriver, pliers and an awl. After removing the rings, you can begin pressing out the bearing. If you do this with a hammer, then try to hit it literally and sharply, so the bearing will come out faster.

Rear wheel hub: drawings and replacement instructions

The place in the ranking is determined by the votes of car owners. The best producers are selected by the ratio of votes, and the Popular ones by the difference. More details

Hello! Tell! I want to buy regular stamped wheels for a VAZ 2107! I have a question: if the disk should be centered, the diameter of the central hole is 58.1, for example, standard, but the disk is sold at 60, is this difference large and you need to buy a centering ring or can you install it and drive?! Strangely, the wheels are standard, but the center diameter is different!

While the turner was working, I decided to fix the problem with the number. its fastening was welded to a 2*2cm beam, it always clung to it, it bent and bent the number. The number is transferred to the body of the trailer, and instead of 2*2 we use 4*4

Bearing sizes

The article contains a photo of the VAZ-2108 front hub bearings, as well as a drawing of a puller indicating all dimensions. Therefore, if you doubt whether you got the right roller, check the dimensions of the hub. The part number is 256907.

The dimensions of the element are:

1. The outer diameter of the holder is 64 mm.
2. Internal diameter – 34 mm.
3. Weight – 445 g.
4. Balls with a diameter of 9.525 mm are installed inside.
5. The total number of balls is 28.
6. The unit is designed to operate at rotation speeds above 6000 rpm.

In any auto store, salespeople will be able to recommend a higher quality product for you.

Causes of malfunctions

And now about why the VAZ-2108 front wheel bearing breaks. Its dimensions (with a mass of 445 grams) are as follows:

1. Width - 3.7 cm.
2. Internal diameter – 3.4 cm; external – 6.4.

The most common reasons why a bearing lasts a long time is water ingress or impact. The bearing temperature increases if you drive for a very long time on the highway at high speed. If after this you get into a puddle, especially if you drive for a long time in swampy areas, the bearing will end up in the water. At this time, almost all the lubricant is washed away. After a short time you will hear extraneous sounds. It is worth noting that front-wheel drive VAZ cars, starting with model 2108, use a bearing consisting of two rows. It does not need to be lubricated during operation, so the risk of water washing away all the lubricant is extremely small. Very often, the cause of premature failure of the wheel bearing is driving on uneven roads. For example, when you are moving at speed, notice a hole, and begin to press the brake pedal sharply, then you are causing enormous damage to your car. Oddly enough, getting into a hole at speed without pressing the brake is much safer. The fact is that inertial forces arise, weight begins to move from the rear axle to the front. And when a direct impact occurs, the front wheel bearing is subjected to many times greater forces. For this reason, the front wheel bearing of the VAZ-2108 will need to be replaced.

Manufacturers

Almost all motorists do not know which VAZ-2108 front wheel bearing to choose for their own car. At the moment you can meet several manufacturers on the market:

1. GPZ-23, Vologda, has the abbreviation VBF. The plant has earned the trust of motorists and is one of the best manufacturers of wheel bearings for Russian cars. Due to the relatively low price, these parts are virtually uncounterfeited.
2. SPZ, Saratov - as almost all experts believe, the bearings of this manufacturer are the most reliable, long-lasting and high-quality. And the most important thing is the very low cost of parts.
3. GPZ-20, Kursk is no longer engaged in the creation of wheel bearings, but you can find products in stores and warehouses.
4. Specialists do not speak very well about the Samara SPZ-3. The cost of the bearings is very low, and their quality does not shine, the service life is very short.

Some auto shops try not to get involved with little-known companies that create bad products. That’s why you can only find Saratov and Vologda bearings on the shelves.

List of suppliers

• SNR is the largest French supplier in Europe and rightfully ranks first in product quality;

• SKF is the second-ranked supplier of bearing products, known in the markets for 100 years;

• NSK is also the second largest manufacturer of wheel bearings in the world from Japan;

• FAG is a manufacturer from Germany, absorbed by the INA concern, with high quality products;

Installing the latest bearing

To simplify installation, you can use a little trick - warm up the hub a little and cool the bearing in the freezer. In the first case, the alloy will expand, in the 2nd case it will contract. Pressing will be much easier and faster. The main thing is not to overheat the hub, otherwise the seal on the bearing will melt and the lubricant will leak out. As a result, you will have to take the latest spare parts and make a new repair.

Lubricate the inner surface of the hub and install the retaining ring on one side. Carefully now you can begin to press in the wheel bearing of the VAZ-2108. If the dimensions are correct and there are no deviations in the geometry of the nodes, assembly will not take much time. When finished, install the 2nd retaining ring. Assemble the entire assembly and install it on the CV joint, tightening the bolts at the top and bottom. Replace the ball joint as necessary.

Tightening the hub nut is done with a wrench to “30” with a very enormous force after assembling the entire suspension and installing the car on the wheels. The entire assembly is done in reverse order, do not forget about the marks on the surface of the shock absorber strut. After all the work, make sure that there is no significant wear on the tires - otherwise, do a wheel alignment.

Causes and symptoms of hub wear

You will have to replace the front wheel bearing if you notice several signs of wear.

Sign

Your actions

This may manifest itself as wheel swaying. Play can be caused by loss of efficiency of both the hub itself and its bearing.

When driving, you may hear strange, extraneous sounds coming from the wheels. As the speed increases, the hum only increases, but after that, when the speed decreases, the noise remains at the same level. If the hum comes from one side, then the hub and bearing should be replaced only on that side. If on both sides, then replace both

Fast bearing heating

A rather dangerous diagnosis that leads to overheating of the calipers. As a result, they also fail. Plus, the brake fluid begins to boil faster, which leads to brake failure. Therefore, the problem should be corrected immediately

Checking the bearing for play

Diagnostics of the play will allow you to determine whether it is necessary to remove and replace the wheel bearing, or you can correct the condition of the unit and calmly continue to operate your VAZ 2109 for some time.

Checking for play

Checking the front wheel bearing play is a simple task that even a beginner can handle. It’s not worth going to a service station and spending money.

By following the instructions, you can easily determine the backlash.

1. Raise the vehicle high enough so that the wheels are off the ground. You'll need a good jack.
2. If there is an inspection hole, then you can do without a jack.
3. Bleed the wheel. It is important to hold the wheel on both sides and clamp it as firmly as possible. You need to swing away from yourself in the same direction.
4. If a slight play is felt, try tightening the bearing nut more firmly. Sometimes, while driving on bad roads, it loses its grip, hence the backlash.
5. If tightening the nut does not help, you will have to replace the hub or bearing.
6. It would be a good idea to check for play by swinging the wheel in different directions, pressing the wheel towards you with one hand, and shaking it away from you with the other.
7. If such a swing shows that there is play, the culprit is no longer the bearing and hub, but the steering tips. They need to be replaced.
8. Replacing the upper ball joint will be necessary if you pull the wheel with emphasis on its upper part and detect play.
9. Pull the lower part already. Play indicates the need to replace the lower support.

wwss75 › Blog › Front wheel spacers for maintenance-free bearing 2108

I rewrote it, corrected it, added it. part 1. HURRAY! It’s done, I’m holding the spacers in my hands. I have long wanted to create one for myself. It’s very difficult with a budget and purchasing via the web is no longer necessary. I couldn’t find it on sale in St. Petersburg, I heard a price tag of 2000 rubles. I contacted turners several times and was shocked by their price of about 6,000 rubles. for work. An old friend Andryukha came to the rescue. I found the time and, according to the drawing, turned it out of 45 steel, accurate to the hundredth. I didn’t take any funds :)) FRIEND! :)) I took the drawing from timur911, here is the link at www.drive2.ru/l/4438002/ In my drawing, 2 dimensions have been changed for the tightest fit of the spacer on the axle. Plus, the accuracy of production of two seating surfaces has a tolerance of 0.01-0.03 mm. (When making the inner surface, the turner makes dissatisfied faces and says that it is lazy and difficult to create) So, my version is a trial one! Everything in size will become clear after installation on the machine. I'll definitely write back. (18 months have passed, everything is EXCELLENT! Everything works! The drawing was corrected and correct 09/07/16.)

Part 2. Verification of dimensions after production during installation. The front brake disc from 2112 does not fit on the rear hub of 2108; it is necessary to grind the hub. I measured the front hub 2112 and got a fit for the disc of 58.5 mm. Since our hub has a larger fit for the brake drums, we grind the hub. The diameter is 58.5 mm on the contact side of the disc brake disc. Here, in this size, great precision is not needed; the brake disc is centered on the hub with bolts. The main thing is that he is dressed all the way to the hub. Bearing and spacer. The dimensions from the rear hub are taken as the base. 2108. This means that the installation of the bearing on our spacer must be similar. I watched a bunch of videos and articles on the web on how to remove and install the rear wheel bearing on a 2108. I also found the dimensions of these bearings and who makes them here. The diameter of the inner bearing race is exactly 30 mm. when measured with calipers 29.95mm. I identified both Russian and the latest bearings imported from other countries when I bought them from the store. The dealers also allowed me to measure the newest rear axle 2108, the size came out to be 30.01 mm. When installed, the bearing should not fit loosely on the axle, it does not have to be free-wheeling. In other words, the bearing fits tightly onto the axle (there should be no greater interference). As a base we take the control for installing the rear bearing. axles 2108.

VAZ 2103-2106

Wheels of the new model were installed on the “three”. In terms of appearance, they are close to the Fiat wheels used on the 2101 version. They have 16 round holes each with an increased rim width of up to 9.5 inches and a reduced offset of up to 29 mm.

Similar models were used for the VAZ 2103 and VAZ 2106 cars. At the same time, chrome caps from a penny were installed on the 2103 versions, and the original ones were used on the six, which were distinguished by a round black trim in the center.

Initially, for the 2106 model, manufacturers planned to use other versions of disks. However, the intended angular style echoed the design of trendy aluminum (alloy) wheels, so they decided not to use them.

On car releases in 1991, wheel covers from model 2101 were used on rims. Since 1995, developers have removed the protrusions for the hubcaps and began producing rims similar to 2103 for all VAZ car models.

To install the disc on the 5 and 7 Zhiguli model with a chrome cap, the diameter of the centering hole was increased to 60.5 mm. Note that such wheels from 2103 without classic protrusions have become a “national treasure” for the entire AVTOVAZ line.

VAZ-2109 Lada Samara is a 5-door front-wheel drive hatchback manufactured by the Volga Automobile Plant. Produced since 1987. This is actually a 5-door version of the VAZ-2108. In 2004, the creation of the VAZ-2109 was transferred to the AvtoZAZ plant in Ukraine. Previously, the car was equipped with in-line four-cylinder eight-valve petrol carburetor engines with a volume of 1100, 1300, 1500 and 1600 cm3. Since 1994, four-cylinder gasoline engines with broken fuel injection began to be installed on these cars.

What can you do to improve your sleep quality?

1. Your pillow should be firm enough to keep your spine straight.

2. You should fill the space between your neck and mattress to keep your head and neck in a neutral position.

3. If you have shoulder pain, try placing a pillow in front of your body and resting your arm on it. This will help relieve the pain.

4. To avoid or get rid of hip pain, try placing a pillow between your knees to keep your hips level.

5. To avoid sagging breasts, try placing a small pillow under them to prevent the ligaments from being stretched. Or just sleep on your back.

6. If you wake up in the morning with a puffy face, puffy eyes and deeper wrinkles than last night, you should change your sleeping position. Sleeping on your back can prevent unwanted contact between your face and your pillow.

7. A good mattress is the most important thing when it comes to healthy and restful sleep. If you're a side sleeper, you'll want to choose a mattress with good shoulder and hip support and a medium to firm firmness. Foam mattresses and mattresses that can “remember” your body position (viscoelastic) are the best options as they are very effective at relieving pressure points.

Of course, other reasons can cause pain and swelling. Therefore, do not immediately think about your sleeping position; maybe the problem is completely different, and the wrong position simply aggravates the situation.
