Instructions for replacing the rear wheel bearing on a VAZ 2114 with your own hands

Diagnostics of the VAZ 2114 rear wheel bearing, causes and signs of wear

Before replacing the rear wheel bearing of the VAZ 2114, it is advisable to check it every 20,000 km, then you can plan for the replacement in advance. To diagnose, we lift the car with a jack, or rather the side with characteristic signs of breakdown:

• Noise from the wheel, turning into vibration;
• The grinding sound indicates that the separator or cages have already been destroyed;
• Increased chassis play - the locknut is not tightened or the bearing has failed.

Advice:

Try tightening the locknut; if the play and noise disappear, the spare part will last for some time.

Steps to diagnose a bearing:

1. Rotate the chassis in a suspended state; if you hear noise or other extraneous sound, the bearing will have to be replaced. The wheel can also slow down when turning.
2. Check the wheel play by moving it axially by hand. If there is no significant play, this does not mean that the part is working properly. Since the axial clearance is checked using a special technique. Focus on point No. 1.
3. To accurately determine the “diagnosis”, unscrew the bolts and check how the brake disc rotates. When the product is in good working order, rotation is easy - without jamming or noise. The video shows the noise that occurs when the chassis rotates if there is a malfunction in the hub assembly. The second video shows details of the replacement.

Preparation for replacing the rear bearing of a VAZ 2114

First of all, before disassembling the unit and replacing it, familiarize yourself with the design of the rear hub of the VAZ 2114.

1. Rear axle shaft
2. Dirt ring
3. Retaining ring
4. Wheel bearing
5. Rear hub
6. Washer
7. Hub nut
8. Pad
9. Protective cap

The VAZ 2114 should be repaired only on a flat surface. Provide free space and lighting for the unit being repaired. First gear is engaged and wheel chocks are installed. Turn off the hand brake and also the pedal brake so that the pads do not interfere with disassembly.

We assemble a set of tools:

• Jack, vice.
• Puller with flat jaws.
• Round nose pliers.
• Set of locksmith's keys, sockets and ratchet.
• Heads 17 and 30.
• Driver or socket wrench.
• The key is momentary.

Do-it-yourself technology for replacing the rear wheel bearing of a VAZ 2114

Removing the rear wheel bearing

1. We start by loosening the wheel bolts and hub locknut before jacking up the car.
2. Now we lift the car with a jack. Screw the hub nut all the way and remove the wheel. Unscrew the drum mounts.

1. We remove the drum. Try to loosen it with your hands first.
2. If that doesn't work, treat the joints with WD-40.

Advice:

The drum is difficult to dismantle; it has not been removed for a long time. To facilitate dismantling, screw the studs into the holes and tighten them one by one, as in the photo. You can also use a hammer.

1. We gain access to the hub and locknut. Unbend the stopper and unscrew it. To enhance the torque, we use an extension for the wrench in the form of a pipe.

1. We compress the hub. To do this, install a puller with paws, as shown in the photo. We grab the back of the hub, focusing on the end of the axle. We tighten the removable device, so the part will gradually be removed.

1. Inside the housing there will be an outer part of the product with a separator and rollers, and an inner race on the shaft. If you are going to change the pads, then unscrew the axle shaft fastenings.

Attention:

If the pads do not need to be changed, go straight to step No. 10.

1. Having unscrewed the bolts, we dismantle the structure (trunnion, brake flap with pads). We help by hitting the screwed hub nut with a hammer. Don't turn the axle shaft!

1. The brake shield will be removed along with the axle, the rear part of which is usually stuck. We knock on it and dismantle it.

1. We remove the wheel bearing race from the mounting surface of the axle using a puller. The same operation is also carried out directly on the car, without removing the axle shaft, if replacement of the brake system is not required.

1. Now let's move on to the hub. We install it as shown below, for example, between two bricks or bars. We select a head to match the diameter of the inner race, with the help of which we knock the part out of the hub with hammer blows. Dismantling is complete.

Installing the rear wheel bearing on a VAZ 2114

1. We clean the hub from dirt, wash it in gasoline, and do the same with the axle shaft. Next, lubricate the seating surface of the hub with thick lubricant. We place the ball bearing on the hub hole, evenly and without distortions, for this there are mounting chamfers.

1. We press the new spare part with our hands and insert it 3 mm. Now you will need an old bearing, which we install on top.

Advice:

The ball bearing can first be cooled in the freezer and the hub heated.

1. Using even blows from the side of the hammer, we gradually hammer the part into the hub. Make sure there are no distortions.

1. After the ball bearing goes all the way, it becomes possible to insert the retaining ring; install it using pliers. We also lubricate the axle.

1. We attach the assembled structure to the axle, evenly, without distortions. Next, we put the washer on the thread and screw on the hub locknut.

1. Now we tighten the nut, with which we press the hub onto the axle, do not forget to lock it. The tightening torque is shown in the table below. After this, we install the drum, fasten it and screw the chassis.

The threaded connections are finally tightened with the car lowered, without a jack.
