Rear hub — removal and installation (BMW 3 Series E46)

Note: Do not remove the hub unless absolutely necessary, as this will require replacing the bearing. The inner race of the hub bearing is a tight fit, so removing the hub will usually cause the bearing to fail. Purchase a new bearing before removing the hub.

Note: To install the hub you will need a long bolt and a set of washers.

Removal

1. Remove the drive shaft (see chapter 8).

2. Remove the brake disc (see chapter 9).

3. Attach an impact puller to the hub and knock the hub off the bearing. If the inner bearing race remains in the hub, you will need a puller to remove it.

4. After removing the hub, carefully inspect the bearing and make sure it is not worn or damaged. Make sure the bearing rotates smoothly and without jamming. If the inner ring of the bearing remains in the hub, or you have doubts about the performance of the bearing, replace it (see paragraph 10).

Installation

5. Lubricate the surface of the hub and insert it into the inner ring of the bearing.

6. Using a long bolt, press the hub into the bearing.

Note: Do not attempt to force the hub into place with a hammer as this will almost certainly damage the bearing.

7. Remove the bolt and washers and make sure that the hub rotates smoothly and without jamming.

8. Install the brake disc (see chapter 9).

9. Install the drive shaft (see chapter 8).
