Removal and installation the wheel bearing (Opel Corsa B)

The wheel bearing on the Opel Combo is located in a separate wheel hub, while on other models it is located directly in the brake drum. In addition, the wheel bearings and brake drum on the Combo have a more robust design.

Removal

1. Jack up the rear of the car and place it on supports.

2. Remove the brake drum (see Chapter Brake system).

3. On the model Combo remove the bearing dust cover with a wide screwdriver. Remove the cotter pin from the wheel journal nut and loosen the nut. Remove the hub with the pressure plate from the journal.

5. Remove the inner tapered roller bearing.



6. Carefully knock out the inner bearing race using a brass drift. To prevent the race from warping in the hub, install the drift alternately at opposite points of the ring.

Installation

1. Always replace the bearing as a set (inner and outer races and rolling elements), even though only one of the clips may appear worn.

2. Check the axle shaft for damage and wear; if necessary, contact a service station to replace it.

3. Install the bearing races until they stop. If there is no special tool for this, press the ring on using a piece of suitable pipe.
