The rear wheel bearing assembly consists of 2 roller bearings manufactured to tight tolerances and matched to size during assembly. The hub bearing is located in the wheel hub or in the brake drum.
Examination
- Loosen the wheel nuts with the vehicle on the ground.
- Mark with paint the position of the wheel disk relative to the hub. Due to this, the balanced wheel is installed in its original place during installation.
- Raise the back of the car see par. 29.
- Remove wheel.
- With the hand brake released, turn the brake drum or disc by hand. The bearing must provide easy and uniform rotation.
- Remove brake drum or brake disc see 18.8.
- Check the axial play of the hub using a dial gauge. The bearing must have a play of no more than 0.2 mm, otherwise, tighten the hub nut and check the amount of play again. If the play remains high, replace the bearing.
- Put the wheel on, while observing the markings made. Lower the vehicle and cross-tighten the wheel nuts. Torque see 19.4.
