Cars up to 9/89 issue and "station wagon" models (not all-wheel drive)
The races of the two-component hub bearing on cars up to 9/89 are located in the brake drum, on cars with rear disc brakes - in the brake disc. After each installation, the bearing play must be adjusted with a nut.
Removal
1. Remove the brake drum or brake disc, see Chapter Brake system.
Attention! The hub nut on the left side of the car has a left-hand thread, to loosen it you should turn it to the right (clockwise).
2. Remove the released bearing parts.
3. Wipe and inspect the bearing races. If there are any defects or visible wear, the entire bearing must be replaced. Do not disassemble the bearing unless necessary.
4. Remove the oil seal.
5. Knock out both outer ferrules with a brass rod. Move the rod around the circumference to different places to avoid skewing the ferrules.
Caution! Do not use a steel rod to avoid burrs forming on the collars.

6. In case of wear, remove the inner bearing race from the journal using a standard puller.
Installation
1. Always replace the hub bearing as a set (inner and outer race as well as rolling element), even if only one clip is damaged.
2. Visually inspect the journal for damage and wear; replace if necessary.
3. Evenly hammer the bearing races "C" with a hammer and brass rod until they stop. It is better to use a stationary press, if available, with a mandrel of the appropriate diameter.
4. Fill the tapered roller bearing with grease (lithium).
5. Insert the inner bearing.
5. Press evenly new seal with a flat plate, do not hit the seal directly with a hammer.
6. Coat the seal with grease.
7. Install the brake drum or brake disc and at the same time also insert the outer tapered roller bearing, see Chapter Brake system.
8. Adjust the hub bearing play.
9. Screw the wheel on, taking into account the mark on the hub. Lower the car and tighten the wheel nuts crosswise with force 100 Nm.
