Wheel Bearing Unit, Removing And Installing: Removing
-- Remove the drive axle bolt. Refer to DRIVE AXLE BOLT, LOOSENING AND TIGHTENING .
The wheel bearing must not be under load when the drive axle threaded connection on the wheel side is loose.
If the wheel bearings are under the load of the vehicle weight, the wheel bearing will be damaged. This reduces the service life of the wheel bearings.
The drive axle bolt may be loosened maximum 90° when the vehicle is standing on its wheels.
Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If a vehicle must be moved, be sure to note the following:
- Install an outer joint in place of the drive axle.
