Removing
- Loosen drive axle bolt to wheel hub:
• Hex head bolt, refer to => [ Drive Axle Hex Bolt Connection, Loosening and Tightening ] Description and Operation.
• Twelve-point bolt with ribs, refer to => [ Drive Axle Twelve-Point Bolt with Ribs, Loosening and Tightening ] Drive Axle Twelve-Point Bolt with Ribs, Loosening and Tightening.

The wheel bearing must not be under a load while the drive axle threaded connection on the wheel side is loose.
If the wheel bearings are under the load of the vehicle's own 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.
• Tighten the outer joint to 120 Nm.
- Remove the wheel.
- Remove the lower noise insulation.
- Remove the nuts - arrows -.
