Rear hub bearings — adjustment (Audi A4 B5)

1. Place chocks under the front wheels, engage steam or "P". Raise the rear of the vehicle and install safety stands.

2. Carefully remove the hub cap.

3. Remove the cotter pin, remove the locking ring and loosen the nut slightly.

4. Slowly tighten the nut until it touches the thrust washer. While tightening the nut, rotate the hub so that the bearing rollers "find their place". Unscrew the nut by one edge so that the thrust washer can barely be moved with a screwdriver (Fig. 8.4). Install the locking ring and insert a new cotter pin.



5. Be careful not to overtighten the nut to avoid premature bearing wear. If you are adjusting the nut of a bearing that has not been adjusted for a long time and there is some play, do not overtighten the nut to compensate for wear, this is potentially dangerous and may cause the bearing to seize.

6. Place a small amount of grease into the cap and carefully install the cap.

7. If a new bearing is installed, it is recommended to check the bearing adjustment after several hundred kilometers.
