Wheel Bearing Overview

Wheel Bearing Overview

• Welding and straightening work on supporting or wheel carrying components of the suspension is not permitted.

• Always replace self-locking nuts.

• Always replace corroded bolts/nuts.

• Bonded rubber bushings can only be turned to a limited extent. Therefore, the threaded connections of the components with bonded rubber bushings should only be tightened when the wheel bearing housing is lifted (curb weight position). Refer to => [ Rear Axle, Lifting to Curb Weight Position ] Rear Axle, Lifting to Curb Weight Position.
