Adjusting the wheel bearing on a VAZ 2107
You can correctly tighten the front wheel bearing of a VAZ 2107 as follows:
If play and noise cannot be eliminated in this way, the bearing must be replaced.
The replacement procedure is quite simple. To replace the VAZ 2107 wheel bearing, you will need:
The work is carried out on a lift or after raising the front wheel with a jack.
- lift the car on a lift or “hang” the wheel using a jack;
- Unscrew the wheel mounting bolts;
- remove the wheel;
- unscrew the caliper mounting bolts;
Tips for replacing a wheel bearing
Timely elimination of play is a guarantee of long bearing service.
Welcome, friends, to the DIY car repair website. While driving your car, noise occurs in the front part of the suspension, a hum, sometimes even a whistle, this indicates that the VAZ 2107 wheel bearing most likely needs to be replaced.
In the front hub of the VAZ 2107 there is a pair of roller bearings, one internal, and the other, of course, external.
How to check a wheel bearing
- Jack up the car so that the wheel rotates freely.
- We place the stand under the threshold of the car.
- When the wheel rocks in different planes, a knocking noise occurs; it could be a bearing, a ball joint, or possibly a steering linkage, so let’s check further.
- We turn the wheel by hand; when noise appears, it will immediately become clear to you that the bearing needs to be replaced.
In the same way as described above, we check the other side of your vehicle, since most likely the hub bearings have worn out there too.
Bearing condition diagnostics
Often, a faulty front wheel bearing manifests itself in the form of noise when the car is moving. You can verify the serviceability (or verify the malfunction) of the wheel bearings as follows:
- Place the car on a level surface, raise the handbrake lever;
- install wheel chocks;
- raise the car by hanging the front wheel;
- install a stop under the lower ball;
- install a safety support under the body;
- lower the jack;
- shake the wheel with your hands, holding the top and bottom;
- spin the wheel.
If play is felt while the wheel is rocking, adjusting the bearing tightening can help. But usually, if a hum, grinding noise, knocking, or play in the bearing occurs, it is necessary to replace the VAZ 2107 wheel bearing.
Instructions for replacing the VAZ 2107 wheel bearing
Replacing the front wheel bearings, as recommended by the manufacturer, should only be done in pairs.
We jack up the car, be sure to place some kind of stand under the body to avoid an accident, unscrew and remove the wheel.
Next, you need to remove the caliper; to do this, you need to unpin the two bolts on which it is attached and unscrew them. To prevent the caliper from dangling and getting in the way, tie it to the lever.
Then you need to remove the cap that covers the hub nut. We unscrew the nut (on the left side there is a left-hand thread, on the right side there is a right-hand thread), remove the lock washer and pull out the outer bearing.
Replacing the axle bearing
The axle shaft is an integral part of the rear axle of the VAZ 2107. The axle shaft itself practically does not break, but the bearing by which it is attached to the axle housing sometimes fails. Its purpose is to rotate the axle shaft smoothly and evenly while the car is moving. Signs of bearing failure are the same as those of the hub elements. If problems occur, it is necessary to dismantle the axle shaft and replace the faulty part.
Bearing removal
Before starting work, you need to prepare the following list of tools:
- set of socket wrenches with a crank;
- hammer;
- flat screwdriver;
- chisel;
- grinder;
- new axle bearing with retaining ring.
To replace, follow these steps:
- Raise the rear wheel using a jack, then remove it, not forgetting to install stops under the front wheels.
- Remove the brake drum.
To dismantle the drum, you need to carefully strike its inside through a wooden block.
Installing a new part
After removing the bearing, you can immediately begin reassembly:
- Clean the axle shaft from dirt and wipe it with a rag.
- Press the new bearing onto the axle shaft, and then install the retaining ring. To install the latter, it is advisable to heat it up with a blowtorch, which will ensure easier installation and reliable retention after cooling.

Replacing a wheel bearing on a VAZ Seven is not a complicated procedure. To carry it out, you will need to prepare the necessary tools and materials, as well as read the step-by-step instructions. If you choose a quality product and carry out repair work correctly, the bearing will work for a long time without any problems.
Good day, dear reader. The process of replacing the front wheel bearing on a classic is not complicated. If you have the tools and free time, anyone can handle this procedure. In this article you will learn:
- How can you tell if a wheel bearing is broken?
- Which bearing company should I choose?
- What tool will you need?
- How to replace a wheel bearing and how to adjust it.
Assembly of the front hub of a VAZ 2107 car
Now that the old clips have been knocked out, you need to rinse the inside of the hub and you can start pressing in the new clips.
You can press in the clips either in a vice or hammer them in using a special mandrel or a piece of pipe of the appropriate diameter; this is not at all difficult.
Then we fill the hub with new grease, lubricate the inner bearing and insert it, then install the split spacer ring and press in the new oil seal.
Next, we fasten the brake disc and install the hub on the steering knuckle axle, insert a new outer bearing, lock washer, tighten the nut, install the caliper and wheel. In general, we do everything in reverse order.
If there are no special tools, we tighten the bearing as follows: tighten the nut until it stops (pull within reasonable limits) and release it 2/3 of a turn and rotate the wheel. We check the backlash (thermal gap).
The wheel should rotate easily, and the play should be barely noticeable when the wheel rocks. There is absolutely no way to overtighten, it’s better to just miss it. We cotter the nut and put on a decorative cap.
At this point the repair is considered complete. Have a good trip and no breakdowns.
The wheel bearing is an important part that is present in every car. The domestic car VAZ-2107 is also equipped with both front and rear wheel bearings. Failure of the front wheel bearing can lead to the most unpredictable consequences: from rapid tire wear to problems with the braking system. There is one way to avoid such consequences - timely diagnostics of the car, adjustment and replacement of worn-out wheel bearings. What is replacing the front wheel bearing of a VAZ-2107, we will find out in this material.
Should there be any play in the wheel bearing, what is allowed?
Yes, there should be some play. To be more precise, this is the thermal clearance of the bearing. It is needed so that when heated it can easily expand. As you know, while driving, wheel bearings experience heavy loads and get hot. Accordingly, the material expands. Without this clearance, wear will increase. The result is complete destruction of the separator and subsequent jamming.
In case of large backlash, destruction occurs. Yes, they won’t get very hot, they will have room for thermal expansion. But if they dangle in the clips, they will break. As a result, the bearing crumbles and impacts occur in the steering wheel when driving. They may disappear when braking.
Therefore, a small backlash must be present. On different models it varies between 0.02-0.08 mm. As the masters say - on the verge of muscle sensations. It can be measured with a special device or micrometer. But not everyone has it, and since the adjustment of the wheel bearing is carried out in a garage, we will rely on our eyes.
Bearing Failure Determination
Some recommendations will help you make sure that you need to replace the wheel bearing on your VAZ-2107:
- The easiest way to determine the need to replace the hub unit is to grab the front wheel and wiggle it in different planes. If you feel the presence of play, then it’s time for a more detailed diagnosis and most likely replacing the bearings.
- The front wheels of the car should be hung on a jack, while being sure to take precautions: pull the handbrake, install shoes and additional stands under the car. Grasp the top and bottom of the front wheel with your hands and then make movements. It is important to wobble the wheel, and not the car as a whole. Thus, you can accurately determine whether the product in question needs to be replaced.
- Another way to determine the need for replacement is to listen for humming, knocking, and grinding noises in the wheel as it rotates.
What bearings to put
When a wheel bearing requires replacement, the question immediately arises of which part to install. Many people advise using original components. However, today the quality of parts leaves much to be desired and the issue of choice remains quite relevant.
Table: type, installation location, and size of bearings
Installation location | Bearing type | Size, mm | Quantity |
Front wheel hub (outer support) | Roller, conical, single row | 19,5*45,3*15,5 | 2 |
Front wheel hub (inner support) | Roller, conical, single row | 26*57,2*17,5 | 2 |
Rear axle shaft | Ball, radial, single row | 30*72*19 | 2 |
Manufacturer's choice
When choosing a manufacturer of a wheel bearing for a VAZ “Seven”, we can recommend SKF , SNR, FAG, NTN, Koyo, INA, NSK. The companies listed have many locations around the world. These products are of high quality and meet the most stringent requirements.
The choice of bearing manufacturer should be given special attention, since the service life of the product depends on this
Among the domestic manufacturers that supply bearings for cars of the Togliatti plant, we can highlight:
- CJSC "LADA Image" - manufactures and sells original Lada wheel bearings through secondary markets;
- Saratov plant - produces parts under the SPZ brand;
- Volzhsky Plant - uses the Volzhsky Standard brand;
- Vologda plant - sells products under the VBF brand;
- Samara plant SPZ-9.
Diagnostics
To determine whether the VAZ 2107 front wheel bearing needs to be replaced or not, you need to:
- jack up the car;
- place a stop on the lower lever and lower the vehicle (this is done in order to prevent rocking in the silent blocks);
- It is better to grab the wheel from above and below and rock it.
In this case, there should be no backlash. After spinning the wheel, repeat the operation. Spin the wheel; no noise should appear when it rotates. If there is no play, but noise appears, then the bearings definitely need to be changed.
Symptoms of a problem
The wheel bearing must always be in good condition. If the part becomes unusable, this can lead to an accident, since the malfunction is accompanied by large wheel play. As a result, the disc may be sheared off the wheel bolts. If such a situation occurs at high speed, a serious accident cannot be avoided. This indicates that the hub bearing needs periodic inspection, and if play is detected, it needs to be adjusted or replaced.
The main manifestations of a part malfunction are:
- Dry crunch. When a bearing breaks, a metallic crunching sound occurs while driving. It appears as a result of uneven rolling of the rollers due to damage to the separator. It is difficult to confuse this sound with any other.
- Vibration. If the element in question has severe wear, vibration appears, which is transmitted to both the body and the steering wheel. It indicates severe wear of the bearing cage, which can lead to seizure.
- The car pulls to the side. The problem is somewhat reminiscent of the case with incorrect wheel alignment adjustment, since the faulty element does not work correctly due to its parts being wedged.
When a bearing fails, extraneous noise, hum or crunching noise appears
Definition of failure
To determine the condition of the wheel bearing, you need to perform a few simple steps:
- Hang the front wheel on the desired side using a jack, not forgetting to put the car on the handbrake and install stops under the rear wheels.
- Place a support under the lower suspension arm and remove the car from the jack.
- Take the wheel with both hands (top and bottom) and perform movements from yourself to yourself, and no play or knocking should be felt.
- Spin the wheel. If the bearing has become unusable, a grinding noise, hum or other extraneous noise may appear.
To check the bearing, you need to hang and rock the front wheel
When carrying out work with a removed wheel, for safety reasons, it is recommended to place an additional support under the car body, which will protect you in case of a sudden fall of the car.
Adjustment
After replacing the front wheel bearings of a VAZ 2107 during maintenance or the appearance of noise, adjustment begins as during diagnostics by “hanging” the wheel. Further:
- tighten the nut until it stops, but not too much;
- by rotating the wheel and releasing the nut, we look for a position in which its rotation will be sufficiently free, and there will be no backlash;
- lock the nut.
However, it must be added that if after tightening the nut the play disappears but there is no noise, then the bearings should also be changed.
Generator repair
First, you need to clean the generator from dirt, oil, dust and everything that has accumulated on it over the entire period of operation.
Unscrew the pulley nut, placing the generator so that the pulley rests on the floor, and then put a 19mm wrench on the nut. While holding the pulley from turning, it is necessary to make several strong and accurate blows on the key. It is unlikely that you will be able to clamp the pulley tightly with your hand, but your efforts may be enough to tear the nut out of place.
Using a 10mm wrench, you need to unscrew the 4 bolts of the tie rods that assemble the generator device into one whole. Using a chisel, knock out the key. This can be done by installing the generator with the shaft up. Place the chisel against the key and start knocking it out with a hammer. Once you have knocked out the key, remove the front cover of the device. If it goes too hard, you need to try to knock it out by weight.
Belt whistles
Often, when a certain malfunction of the VAZ 2107 appears, you can hear an extraneous sound, which allows you to confidently diagnose the problem. One of the malfunctions may be the belt slipping, resulting in a whistle from friction against the pulleys. This problem leads to unstable operation of the generator and lack of battery charge.
How to replace bearings
As in the case of diagnostics, we begin the repair by jacking up the car and removing the wheel. Further:
- unscrew the caliper and hang it so that it does not interfere;
- remove the nut cover on the hub;
- unscrew the nut with a 27 wrench;
- remove the washer;
- remove the hub with the attached brake disc;
- remove the small bearing separator;
- remove the oil seal;
- remove the large bearing separator;
- remove the clips with a puller or knock them out with a hammer and chisel;
- remove old grease from the hub and cap.
We perform assembly in reverse order.
- press in the bearing races;
- lubricate and install the inner bearing separator;
- install the oil seal;
- put the hub in place;
- lubricate the outer bearing separator and install it in place;
- install the pressure washer;
- tighten the nut;
- screw the caliper into place.
At this point, the replacement of the front wheel bearing of the VAZ 2107 is completed and all that remains is to adjust the tightening of the nut, this is done as I already described above.
