Rear wheel hub: drawings and replacement instructions

Any spare part for a VAZ 2108 is special. The rear wheel hub component is special and a large number of elements are assembled from simple elements. Quality workmanship and adherence to important processes guarantee operational efficiency.

A schematic drawing of the rear wheel hub spare part shows the assembly of the listed elements. Especially the wheel hub cap, bearing washer, wheel bearing, etc. The numbers and schematic drawing are available here.

The information on the VAZ 2108 provides a detailed description of the various spare parts among which this car is manufactured. In addition, the rear wheel hub part is not an error.

The wheel is attached to the rear hub of the VAZ-2108 using four bolts. There is also a brake drum here, with the help of which the car stops. The hub itself fails very rarely; it is usually replaced when the inner surface or threads into which the wheel mounting bolts are screwed are damaged.

It is much more common to remove the hub to replace the bearing. This is the most vulnerable element of the structure. Driving with a broken bearing will not bring much pleasure, as extraneous vibration and noise will appear, which intensifies when accelerating and cornering.

How to check a wheel bearing

If the rear wheel bearing of a VAZ-2108 breaks down, you will hear a characteristic howl coming from the trunk. Try to listen to which direction the sound is coming from. This will allow you to reduce the time spent searching for a faulty bearing. To make a diagnosis, you need to lift the wheel and then rotate it by hand.

If the bearing is in good condition, there will be no noise. The wheel should rotate without jamming. But if the bearing is faulty, then a strong noise will appear, as well as a metallic sound, as if the balls inside the bearing are rolling. The louder the noise, the greater the wear on the wheel bearing. It is advisable to replace both sides at once, this will improve the efficiency of the repair.

Maximum and minimum acceptable parameters of non-standard disks

The size of the wheel arches on the VAZ 2109 limits the possibility of installing wheels with a diameter larger than R15. It turns out that any non-standard specimen must fit into the dimensional frame of 13-15 inches. It is impractical to look for something smaller, and to install a larger diameter, you will need to increase the wheel arch, that is, change the body structure.

Limiting yourself to the given parameters of the arch, you need to look at the other indicators of the non-standard disk. To connect parts with different bolt patterns, you can use adapter spacers. In this case, the problem of incompatibility of the disk with the hub according to the holes is quite easily solved.

The main thing is to choose suitable fastenings. The width of the rim, according to the limits set by VAZ designers, is limited to 4-7 inches. Exceeding these parameters may impair vehicle handling and raise questions during registration.

The permissible disc overhang is directly related to its width and design. In the factory assembly, this figure ranged from 30 to 45 mm. You can change the offset using spacers.

But you need to remember that as the offset decreases, the track width increases, and wide tires may exceed the established overall dimensions of the vehicle. The central hole of a non-standard disk must be at least 58.5 mm.

Although the options for replacing disks on a VAZ-2109 are limited to certain parameters, there are still quite a lot of them

But, first of all, you should still pay attention to original products that are maximally adapted to the given car. It’s easier, safer, and more profitable from a financial point of view.

What tools will you need?

Before replacing the rear wheel bearing of a VAZ-2108, you will need the following tool:

1. A 30" head and a knob, as well as a piece of pipe. You can even use a spanner wrench, but it must be strongly curved to make it easier to install into the hub hole on the nut.
2. Punch or thin chisel. It is advisable to sharpen the chisel in advance. This tool is needed to straighten a jammed edge on a nut.
3. It is advisable to have three-legged and two-legged pullers. The first is necessary to dismantle the wheel hub, and the second to remove the inner race of the bearing.
4. Pliers for removing and installing retaining rings.
5. It is advisable to have a puller on hand to remove and install the bearing into the hub.
6. You will also need any type of keys for “12”, “13”, “14”.
7. You can't do without a hammer and wooden spacers.

Be sure to buy a good bearing, it is advisable to also buy a nut. It is not recommended to use the old one. You can purchase an assembled VAZ-2108 rear hub, this will greatly facilitate repairs, but will hit your wallet hard.

What is the diameter of the hub (exact factory data)

According to the regulatory documentation provided by the manufacturer, the hub diameter on the VAZ-2114 is 58.5 mm.

Thus, the bolt-to-bolt size is 4x98 , which allows you to install wheel rims with sizes R13, R14 and R15 . To secure the wheels to the hub, use bolts measuring M12x40 mm .

Standard stamping for factory hub

In order to choose non-standard stampings, but, for example, non-standard alloy wheels, it is necessary to change the size of the hub and the inter-bolt space. Of course, the manufacturer and car enthusiasts do not advise doing this unless absolutely necessary, so you should think several times before taking this action.

The most common size on European cars is 4*100 . Therefore, many people want to install just such disks. This is the hub size for Hyundai Accent and Renault Logan.

What is a classic of the Russian automobile industry? This, of course, is any car produced by AVTOVAZ models 2101-2107. They have become classics due to the years of production, and, as a result, their long presence on the market. The same VAZ 2107 could change 5 or 8 owners during its service life. Fortunately for old-timers, modern technology allows them to be upgraded to the highest possible level. So, it is possible to replace the rear bearings with double-row ones. However, there is one important nuance for this tuning - namely, the implementation of the transition. For those who want to get by with little expense, we offer for purchase a bushing of non-adjustable hubs.

Of course, this element (sleeve or adapter) can be machined yourself, since the Internet is full of drawings. But if you calculate the time and labor costs, it becomes obvious that buying a ready-made bushing is a more reasonable and reliable option.

Preparation for repair

All work must be carried out on an inspection pit or overpass. But if you do not have such amenities, you will have to hang the rear of the car so that it is above the ground. The procedure for carrying out preparatory work:

1. Place the car on a level surface.
2. Place blocks under the front wheels.
3. Turn on first speed.
4. Loosen the nut that tightens the handbrake actuator (optional).

After this, it is necessary to loosen the bolts securing the rear wheel on which the repair is being carried out. It is also advisable to unscrew the nut on the hub, and then rip it off using a “30” wrench. You can then hang up the side of the car to make further repairs.

Methodology and algorithm of repair work

Replacing a hub or bearing on a VAZ-2108 car is a clear technological process in which certain procedures will have to be followed. The first stage in the replacement process is preparatory. It is necessary in order to correctly assess the upcoming scope of work, prepare the site and the appropriate tools.

1. Jack. In order for the problem unit to be replaced, you must first hang the wheel, removing the weight load from it. To do this, the vehicle is raised with a jack. If the replacement is carried out in a car service center or a specially equipped garage, then use a lift that will allow you to raise the car to a comfortable height.
2. Puller. Replacing a hub or bearing on a VAZ-2108 requires the use of two different pullers, the sizes of which - 3 and 6 cm - correspond to the diameters of the rotation support races.
3. Pliers.
4. Wrenches for 12 and 30.

Under any conditions, replacing the rotation support begins with dismantling the hub unit.

1. The front wheel is removed from the side of the defective unit. To do this, the car is secured with the handbrake and the mounting bolts are loosened. Then, on a jacked-up VAZ-2108, the bolts are completely unscrewed and the wheel is removed.
2. The brake disc is removed.
3. The caliper does not unscrew completely. It will have to be secured in this position, for example, with wire.
4. After this, using a puller, we dismantle the hub along with the bearing.

The algorithm for further actions depends on which of the two units requires repair. In any case, the bearing will have to be pressed in, otherwise manipulations with the hub are impossible. Assembly of the unit occurs in the reverse order.

Removing the hub

To remove the rear wheel hub of a VAZ-2108, you will need to perform a few simple manipulations:

1. Completely unscrew the wheel bolts.
2. Remove the wheel.
3. Unscrew the nut that is located on the hub.
4. Using a 12mm wrench, unscrew the studs that secure the brake drum to the wheel hub.
5. Place these pins in adjacent holes and tighten them evenly. This way you will be able to move the brake drum from its place. If this does not help, you need to carefully knock the drum out of its place using a hammer and a wooden spacer.
6. Use long bolts; they need to be screwed into two opposite holes on the hub. It is necessary to tighten them until the hub begins to move out of its place. You can also use a three-jaw puller for this purpose. The last resort is to install the back of the wheel and pull it with your hands.
7. Sometimes the inner race of the bearing remains on the axle. It needs to be removed. To do this, first, using a chisel, you need to slightly move this ring on the axis, and then install a puller with two legs. After dismantling, be sure to check that there is no damage to the axle. Otherwise, clean the metal with a fine file.

At this point, dismantling the hub is completed, it is in your hands, and you can replace the bearing. The dimensions of the rear hub of the VAZ-2108 are the same as those of similar models that were produced under the names “Samara” and “Samara-2”.

What is a hub and why is it needed?

In mechanics, a hub is the central part of a part with a hole (usually it looks like a keyway) for fitting onto a shaft, in particular onto a trunnion. Also, spokes are attached to the hub.

This is what the hub looks like

This important spare part ensures the movement and controllability of the car. Its main functions:

• wheel mount;
• its rotation;
• transmission of torque from the transmission to the wheel, that is, the connection between the shaft and the disk.

How to remove a bearing

The most interesting thing is yet to come - you need to remove the bearing from the hub. To do this, follow these steps:

1. Use pliers to remove the retaining rings. If you don’t have such a tool, you can use a thin screwdriver or an awl.
2. It is advisable to use a special puller to remove the bearing. It is installed on the element over its entire area; when the nut is tightened, the bearing is evenly squeezed out. But if you don’t have such a tool, you can use the outer race from an old bearing. Applying blows evenly, remove the element from the seat.

The dimensions of the rear wheel bearing of the VAZ-2108 are slightly smaller than those of classic series cars. But this does not mean that they are very weak. If the bearing is installed correctly, it will last a long time.

How to recognize malfunctions

There are many signs that help identify a breakdown:

• uneven wear of tires;
• increased vibration;
• the appearance of extraneous noise;
• overheating of the disk (this means that the bearing is not working properly);
• the car deviates to the side from a straight path and the body sways (these signs are explained by the fact that a working wheel ensures smooth movement, and when a breakdown occurs, imbalance occurs).

Important! The most characteristic “pattern” is the sound in the rear chassis.

The easiest way

If all of the above is not picked up by the hearing and vestibular apparatus, then there is an optimal method. You need to push the tire with your foot to identify any play.

Note! This method is very effective in the initial stages, when the symptoms are least pronounced.

Installing a new bearing

Before installing a new element, it is necessary to inspect the entire internal surface. There should be no nicks or damage on it. To make installation a little easier, you can place the new bearing in the freezer for several hours and warm up the hub. But please note that it should not be heated to very high temperatures.

Otherwise, when installing a new bearing, its seals will melt, which will significantly reduce the life of the element. The bearing must be pressed in using a puller or using a clip from an old element. Be sure to secure the position of the bearing with the circlips, making sure they fit into their grooves.

What drives can be installed

When planning to replace old steel wheels with alloy wheels, you should choose either original products or products from well-known manufacturers who care about the quality and safety of their products.

Alloy wheels combine the following useful properties: they are lightweight, practical to use, endowed with sufficient strength and have an attractive appearance, which is aimed at transforming the entire appearance of the car.

The most common among alloy wheels are aluminum products. This is due to the fact that they are resistant to corrosion, meet strength requirements and, in comparison with other alloy wheels, remain relatively inexpensive.

The latest models from AvtoVAZ use wheels with a 4x100 mounting pattern. When installing them on a 4x98 hub, you should use studs with an eccentric to compensate for the difference of 2 mm. To install disks with other mounting patterns, you will have to use the appropriate adapters (spacers).

You must understand that installing wheels larger than 15 inches is impossible without interfering with the car’s design.

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.

Structure

The part has a fairly simple structure. Essential elements:

• outer rim (used for screwing in bolts);
• internal part (for bearings);
• holes with slots (for CV joint);
• protective caps;
• sensor (it is sometimes included in the design).

CV joints are constant velocity joints; their main task is to transmit torque.

Note! The set of fasteners for this part consists of two nuts and one washer.

Hubs for different purposes have different technical characteristics. Hubs for passenger cars have the form of a hollow, lightweight cylinder, while for “heavyweights” the diameter of the part is larger.

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.

How to install a 4x100 disk on a VAZ-2114

Most older foreign cars have a 4x100 drill. This makes it possible to diversify the choice of disks almost indefinitely. However, we must take into account that simply installing, without modifications, 4x100 wheels on a 4x98 seat will not lead to anything good. The fact is that the tolerance in the manufacture of the disk does not exceed 0.7-1 mm. That is, it is theoretically possible to put on a disk with a 4x100 fit, but this will lead to the fact that only one bolt out of four will fit exactly on the cone. The remaining fasteners simply will not tighten all the way and, as a result, the disk will sit with a distortion that is almost impossible to check by eye.

Disc with bolt pattern 4*100.

Disc runout leads to rapid wear of the wheel bearing.

A less reliable option is to install bolts with an offset head. A not entirely correct option is to install studs, for example, from the cylinder head and nuts from Niva, but the studs are not designed for torsional force, so the most reliable option would be to install spacers. You can carve them yourself or buy them ready-made.

But here you need to take into account several nuances:

1. The width of the spacer must be at least 20 mm, since only in this case we will ensure proper thread strength.
2. In this case, the offset of the disk will increase by the same 20 mm, which must be taken into account when selecting a disk.
3. In this case, the disc must be selected with a minimum offset in order to remove the load from the hub and somehow compensate for the difference in offset.

Using off-center eccentric bolts Installing wheel spacers Installing studs with an eccentric nut

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.

Standard disk sizes

The main technical characteristics of the rims of any car, including the VAZ-2109, are expressed by the following parameters:

• Diameter. This refers to the size of the rim in inches, excluding the tire.
• Rim width is the size of the tire seat in inches.
• The size of the central hole for the hub.
• Bolt pattern is a parameter indicating the number of holes and the diameter of the circle connecting their central points.
• Overhang is the distance between the hub mounting surface and an imaginary plane passing vertically through the middle circumference of the disk.

1. The central hole is 58.5 mm.
2. Bolt pattern - 4x98.

The wheels are manufactured in three versions: R13, R14 and R15. Other factory parameters, taking into account the corresponding tires, are shown in the table.

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.

Replacement procedure

DIY stand for storing car wheels drawing

Lubricate So, we have determined that this cannot be done with a little blood, and the car really needs to replace the bearing. Therefore, we adhere to a clear procedure and begin work.

1. Remove the brake drum. There should be no problems with this, since it is fixed quite simply on the rear wheel.
2. Pry up the hub cap using a flathead screwdriver and remove it.
3. Now, using a narrow chisel, straighten the collar of the nut, which was jammed in two places at once. Don’t be afraid, it wasn’t you who did something, such a jam is provided at production so that the element does not fly out of its rightful place.
4. Use a 30mm socket to unscrew the fastening nut.
5. Remove the unscrewed nut and also dismantle the thrust washer.
6. Arm yourself with a three-legged or two-legged puller, which will allow you to remove the hub from its place.
7. If you don't have a three-jaw tool, press out the hub using two bolts or screws. As the practice of craftsmen has shown, bolts for fastening the head of a power unit are excellent for these purposes.
8. Screw the screws into the opposite holes for fastening the wheel and rest their ends against the heads of the bolts securing the hub axle to the rear suspension beam of your car.
9. Try to tighten the screws evenly to allow the hub to press out. There is no need to remove the pads.
10. As a rule, the inner race of the bearing should remain on the hub axis.
11. Secure the ring using a puller, then remove it.
12. If you don’t have a puller, you will have to additionally dismantle the brake pads and use a chisel to mix the ring to the axle.
13. Next, the ring moves. Two mounting blades will help you with this.
14. Do not be afraid that after processing with a chisel, some kind of defects or nicks will form on the hub axis. This is not terrible, but it is highly recommended to process them with a needle file.
15. Arm yourself with pliers, thanks to which you can carefully remove the retaining ring.
16. Using a piece of suitable pipe, also carefully knock out the bearing, leaning on the inner ring.
17. Another option is to press it out using a wheel bearing puller.
18. Clean and effectively lubricate the hub into which the new rear wheel bearing is pressed with a puller or vice. The pressing force must be applied to the outer ring. It will be most convenient for you to do this using the outer ring from an old bearing.
19. Install the new retaining ring in its proper place.
20. Using light blows on the inner ring, press the bearing onto the axle. Drive until deep enough to fit the nut.
21. Full pressing is carried out with the nut already on.
22. Be sure to use only the specified torque to tighten the fastener.
23. Press the collar of the nut into the two grooves of your hub axle to restore the element to its original appearance.

This procedure cannot be called incredibly complicated, but you will have to “tinker” in your garage. But this is better and more cost-effective than going to a service station and entrusting your car to unknown specialists.

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.

Rear wheel hub: drawings and replacement instructions

Vehicles have to be periodically repaired, and on bad roads the hub mechanism often breaks down. But how to change this part on a VAZ 2108 or 2110? Why does it break? And how to replace the rear wheel hub bearing? These issues will be discussed below.

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.

Diagnostics, signs of malfunction, causes of failure

With proper operation, the ball bearing itself can last a really long time - about 100,000 kilometers. However, there are a number of reasons why a part may become unusable much earlier. Among them:

• frequent driving at high speed on bad roads;
• improper installation without lubrication (resulting in overheating and increased wear);
• prolonged exposure to an aggressive environment (water, dirt, other abrasives or liquids that get inside);

It is easy to understand that the ball bearing has failed - a distinct noise or buzz appears in the area of ​​the rear wheels. If you ignore the problem, vibrations will appear on the body, and in critical cases, a grinding noise in the rear, indicating that the assembly has simply fallen apart. It is simply unacceptable to wait any longer - the wheel may simply become blocked while driving, so it is necessary to immediately replace it.

Changing the rear wheel bearing with your own hands

Replacement of the VAZ-2108 rear wheel bearing is carried out in the following order:

1. We install the car on a flat surface, fix the front wheels by placing wheel chocks under them.
2. Remove the cap covering the hub nut.
3. Using a chisel (core), we bend the bent edge of the hub nut so that it does not interfere with its unscrewing.
4. 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.
5. After unscrewing the nuts, unscrew (not completely) the wheel mounting bolts.
6. We lift the body with a jack, fix its position with stumps (bricks), and unscrew the wheel bolts. We dismantle the wheel.
7. Using a key set to “7”, unscrew the guide bolts on the drum (2 pcs.).
8. 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.
9. Now completely unscrew the hub nut.
10. 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.
11. Remove the hub from the axle.
12. Using long-nose pliers or special pliers, remove the bearing retaining ring.
13. We place the hub in a vice and, using a hammer and a piece of pipe, carefully knock out the bearing.
14. When the bearing is knocked out, lubricate the inner surface of the hub with grease.
15. We install the new bearing without removing the hub from the vice.
16. 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.
17. We put the locking ring in place.
18. 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.
19. Screw on the new hub nut. We tighten it until it stops. The hub should still move inward.
20. Install the brake drum and secure it with guide bolts.
21. We mount the wheel.
22. Remove the jack and tighten the hub nut completely. If you have a torque wrench, observe the tightening torque (186.3-225.6 Nm).
23. We bend the edge of the nut, fixing its position.
24. We put a cap on the nut.
25. 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.

Important points

The wheel nut on the VAZ 2109 is tightened very tightly, and in addition, it is often covered with rust. It may take a huge amount of effort to move it. In such a situation, WD-40 liquid can help. If you don’t have this liquid on hand, you can generously pour oil on the nut and wait 10 minutes. Not every car owner has a wheel bearing puller at hand. In this case, to remove the bearing, you can use a hammer and a piece of steel pipe of suitable diameter (about 4.5 cm). The main thing is not to damage the inner surface of the hub with the pipe.

If scratches and gouges remain there after pressing out, the new bearing will quickly fail. When reassembling the hub, special attention should be paid to tightening the hub nut. If it is loosely tightened, play will occur, which will again lead to bearing wear.

Therefore, with a 30 socket head, you should use the longest wrench so that the force when tightening the hub nut is maximum.

Replacing wheel bearings is a procedure that every owner of a “nine” will sooner or later encounter. The only question is whether he will be ready for this. If the driver prefers to repair his car himself, then it makes sense to purchase a puller for hubs and bearings in the store. This simple tool will greatly facilitate the work and also save the car owner a lot of time and nerves.
