Removing

- Remove the driveshaft bolt => [ Threaded Connection Between Driveshaft and Wheel Hub, Loosening and Tightening ] Procedures.

The wheel bearing must not be under a load while the driveshaft 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 driveshaft bolt may be loosened maximum 90° when the vehicle is standing on its wheels.

Vehicles without a driveshaft 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 driveshaft.
