The wheel bearing must not be under load when 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 12-point nut may only be loosened a maximum of 90° when the vehicle is resting 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:
