VAZ 2109 front wheel bearing size

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.

Wheels for VAZ 2109: choice, size, bolt pattern

The VAZ 2109 belongs to the Lada Sputnik family - a five-door modification of the previous model 2108 from the Lada Sputnik family.

Classic models came off the factory assembly line with standard rims stamped from a steel alloy:

• 4 1/2J-13;
• 4 1/2J-13H2;
• 5 J-13H2.

Before deciphering the markings, you need to understand what technical sizes and parameters of car wheels are accepted. Regardless of the manufacturing method, cast or stamped, they are designated in the same way. There is a mark on the outer surface that displays all the necessary information.

This includes:

• name of the manufacturing plant;
• the state where the release took place;
• date (based on the “week/year” principle, example: 1815 – 18th week of 2015);
• X-ray scan marking (light-alloy cast products are checked for the absence of internal cracks and defects);
• dimensions;
• sign of the control department (for Russia - ROSTEST, for Germany - TUV, international organization - ISO, for America - SAE, etc.);
• heat number and permissible load (lb (pounds), kg, example: max load 1800LB - maximum pressure up to 1800 pounds or 816 kg).

Any spare part of a modern car must be perfectly matched to fit and technological dimensions. Unfortunately, the manufacturer does not always take into account the specifics of using materials in spare parts, which affects their service life, reliability, and, ultimately, traffic safety. The chassis of a car is subject to enormous loads, so it is simply impossible not to pay attention to the correspondence of the factory dimensions 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 own standard dimensions, which the roller bearing must correspond to:

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

Only by these parameters can you select a bearing, of which domestic factories produce thousands. Manufacturers from China actively help in 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 performance of such bearings meet the standards. There are bearings without any markings at all, and there are particularly zealous owners who buy them. Such bearings burn out within 1000 km and simply fall apart while driving.

Features of choosing a wheel bearing for a VAZ 2108

Naturally, we will not be able to check the dynamic load on the bearing races and on each of its balls. But you need to remember, like the 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 is 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.

Design of wheel bearings for VAZ 2108

All VAZ cars are equipped with only three types of wheel bearings - wheel bearings for front-wheel drive VAZ cars, wheel hub bearings for rear wheels, and wheel bearings for Kalina and Grant cars, which are smaller in size.

All VAZ bearings are of the HUB-1 type, and this type is characterized by the design and installation features. The bearing has a double-row design, 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 segment, so the demand for them is very high. Because of this, you can often find the fakes we mentioned. However, the transition of the VAZ plant to bearings of this type, instead of roller ones of the old type, made it possible to choose bearings not only of domestic production, but also of many other foreign factories.

The main percentage share of bearings used on VAZ cars lies with domestic manufacturers, among which several factories can be distinguished:

1. Saratov Bearing Plant (SPZ) - 28%.
2. "Volzhsky Standard" - 2%.
3. Samara plant SPZ9 - 8%.
4. "Lada Image" - 7%.
5. Vologda Bearing Plant VBF - 4%.

Let us only note that Lada Image supplies products directly to the plant’s conveyor belt, and SPZ has the largest share in the spare parts market. It is impossible to say anything specific about the quality of workmanship, because there may be failures at every plant, but even if the bearing turns out to be of poor quality, the enterprise must replace it. Prices for VAZ 2108 front wheel bearings rarely exceed 250 rubles apiece, and imported models may cost a little more, but their quality is appropriate.

So, bearings from Kraft, SCT, Trialli, LGR can cost about 300-350 rubles, but these are world-famous manufacturers, and you can definitely count on the quality of the bearing. Choose the right bearings and let your figure eight roll forward with confidence!

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.

Replacing the front wheel bearing of a VAZ 2109 - first steps

Regardless of the replacement method, the initial operations will be similar:

1. Before putting the car on a jack, it is recommended to loosen the front hub nut.
2. Then loosen the front wheel mounts.

1. After removing the wheel, unbend the locknut collar.
2. Next, tighten the bolts that hold the caliper, top and bottom, one at a time.

1. Then use a screwdriver to straighten the pads in the caliper.
2. We hang the caliper or move it to the side. Further operations will follow, based on the specific replacement option.

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.

Replacing the rear wheel bearing of a VAZ 2108 along with the hub

Sometimes there is a situation when a new ball bearing fits into place too easily.

If there is at least some play, this means that the wear is too large and the dimensions of the diameter of the inner ring of the hub are already beyond the permissible limits. Even a serviceable element will give a runout in this state of affairs. If this is the case, replace the unit completely. If the thread is damaged, replacement is also advisable.

The process is exactly the same as mentioned above:

1. Remove the wheel;
2. We dismantle the brake drum;
3. Unscrew the fastening nut;
4. Remove the hub completely;
5. There is simply no need to press out the bearing - just mount the new part in the reverse order of the first three points. The main thing is to lubricate the new elements and tighten the bolts according to the recommendations in the instruction manual.

Mounting values ​​on the disk (bolt pattern parameters)

When installing, it is important to take into account the fitting size recommended by the manufacturer, since differences may be due to different calculation systems (metric or imperial).

• The diameter distance between mounting holes is designated PCD (Pitch Circle Diameter). The accepted scheme on the VAZ-2109 looks like 4x98 or PCD 98/4, i.e. between the central axes of the bolts (4 pieces) 98 mm.
• Fastening elements - metric thread M12x1.25 (bolt stud diameter 12 mm and thread pitch 1.25 mm).
• The central hole for the hub shaft on the disk is designated DIA and for the VAZ-2109 this is equal to 58.5 mm.

Important! Often, car enthusiasts confuse PCD values ​​due to a difference of just a couple of mm. For example, the standard size for the two central holes is just a visually imperceptible deviation of 2 mm - this is PCD at 4/98 and 100. Only 1 bolt will turn out to be completely tightened, and the remaining 3 will be undertightened, which will ultimately lead to an emergency.

Replacing the rear bearing

1. Place the car on the pit.
2. Loosen the wheel bolts, jack it up and remove it. Don't forget about safety and install a stand under the threshold.
3. From the hole, loosen the handbrake tension nut. Head nut for thirteen. You need to unscrew it with an extension cord and a cardan.

Unscrew the two guides using a 7mm socket.

Apply penetrating lubricant, then tap the drum with a rubber hammer and remove it.

Using a power wrench and a 30mm socket, unscrew the hub mounting nut.

Remove the hub from the shaft. If the bearing is severely worn, the outer race may remain on the shaft. It is best to tighten the clip using a three-legged puller.

• Using pliers, remove the retaining ring.
• Using an extension to size, knock out the bearing.

• Clean the seat of the new bearing, as well as the groove for the retaining ring.
• Lubricate the outside of the bearing and the seat.

  Install the hub onto the shaft, having lubricated everything first. If the hub does not melt by hand, it can be installed with a hammer through the extension. It is best to use a 30mm head as an extension.

• Install the spacer washer and install a new nut.
• Tighten the nut to 200 Nm, tighten it and reassemble 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.

Remove the cap covering the hub nut.

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

Bearing selection

To replace a wheel bearing, you will need to know about its parameters, dimensions, and characteristics specific to the VAZ 2109.

For the “nine”, a double-row angular contact roller bearing with tapered rollers is used. Axial clearances are pre-adjusted and filled with lubricant. Closed bearing type.

Based on the table, you can find the optimal bearing for the front hub of your car.

The design of the seven involves drilling 4×98 wheels, where the number 4 indicates the number of bolts, and 98 indicates the diameter of the holes on the disk structure.

Many foreign cars use a bolt pattern with similar parameters – 4×100. In the first situation, the distance between the centering bolts is 69.3 mm, and in the second case - 70.7 mm. The error is 1.4 mm and does not allow for tight fixation of a non-standard disc.

In addition, installing a car disk with non-standard parameters can lead to deformation of elements, namely mounting holes and bolts.

There are other methods for attaching 100x4 rims to the seven. For example, you can use extended bolts, adapter rings, studs and eccentrics. However, these parts can ultimately complicate or impair the mounting of the wheel product.

Therefore, it is recommended to install standard car wheels and tires so as not to lead to wheel imbalance and vibration while driving.

Wheels on the VAZ 2107 are equipped with 13-inch stamped wheels or analogues with identical parameters. Tires have dimensions 175/70/R13.

The nominal pressure in “seven” tires directly depends on the tire sizes:

175/70/R13 – 1.9 rear, 1.6 front wheels;

165/80/R13 – 2.0 rear, 1.7 front.

Wheel bolt pattern on model 2106

For a six, the wheel bolt pattern is 4×98. As for the factory dimensions of the disks, then:

• standard width is 5.0J,
• centering hole 58.5 mm,
• departure ET

Tire size for the six is ​​175/70/R13.

As a restyling, you can install wheels 185/60/14, 195/50/R15.

Standard set of repair tools

To perform a step-by-step replacement of the VAZ-2109 rear wheel bearings as quickly as possible, you will need the following set of tools:

1. Hammer.
2. A small block of wood.
3. Pliers.
4. Puller for retaining rings. If you don’t have such a tool, you can use a flat-head screwdriver and an awl.
5. Socket wrench or socket head “12”.
6. A 30mm spanner or a socket with a reinforced wrench. Tightening is carried out with a very large torque, so you will need to use a small piece of pipe to facilitate the work.

This is a standard set of tools that you need to have to remove and install rear wheel bearings on nines and similar VAZ models.

What tools are needed for replacement?

So, now we need to talk about what devices you may need during the work. Of course, first of all you need a jack and supports. With their help, you can lift the side of the car that is being repaired and fix it in this position. Also, it is necessary to place stops under the rear wheels, which will prevent the car from moving.

You will also need a large and good vice. To press in a new bearing, a special mandrel is needed. It can be made from an old bearing race. Of course, you can’t do anything without a good set of keys and sockets, small pliers, and it is advisable to have a puller for locking rings in addition to them. Phillips and flathead screwdrivers of various sizes will come in handy. It is also worth noting that the front wheel bearing of the VAZ-2108, the dimensions and price of which are indicated in the article, must be changed using special tools. The cost of a set of bearings for one hub is about 400 rubles.

And now about the heavy instrument. The most important thing is the 30mm head with a very large lever. You can also use a spanner of the same size. But not everyone, unfortunately, will be comfortable in this matter. A mounting spatula or small crowbar is also required. When removing the hub, you will need a good marker that will not wear off with impact. And the most important thing is a bearing puller. Without it, repairs will be tedious and very long.

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.
