Rear hub bearings — lining (Opel Ascona C)

1. Raise the rear of the machine. If the vehicle is equipped with stamped steel wheels, there is no need to remove the road wheel, but only the wheel bolt cover plate. If the car is equipped with light alloy wheels, remove the wheel (see Chapter 9, Section 3).

2. Remove the small dust cap from the center of the hub.

3. Remove the cotter pin from the toothed nut on the short axle.

4. Tighten the nut to a torque of 25 Nm (18 Lbf ft) while turning the wheel (or brake drum).

5. After tightening the nut to this original value, loosen the nut so that the thrust washer can be moved slightly. Determine this by trying to move the gasket with a screwdriver. Do not apply the screwdriver to the hub, but simply press it directly onto the gasket.

6. If the holes for the cotter pin do not match the teeth of the nut, tighten the nut until the first such match occurs; then check if the thrust pad can still be moved. If possible, install a cotter pin; if not, loosen the nut to the next position and then install the cotter pin.

7. Check that the hub can rotate freely and without binding, and then reinstall the dust cap.
