Removing
- Loosen driveshaft bolt to wheel hub:
• Twelve-point bolt with ribs, refer to => [ Twelve-Point Bolt with Ribs, Loosening and Tightening, Driveshaft Threaded Connection ] Twelve-Point Bolt with Ribs, Loosening and Tightening, Driveshaft Threaded Connection
• Twelve-point bolt without ribs, refer to => [ Twelve-Point Bolt without Ribs, Loosening and Tightening, Driveshaft Threaded Connection ] Twelve-Point Bolt without Ribs, Loosening and Tightening, Driveshaft Threaded Connection
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.
• Tighten the outer joint to 120 Nm.
- Remove the wheel.
- Remove the lower noise insulation.
- Remove nuts - arrows -.
- Remove both the wheel bearing housing and ball joint from the control arm.
- Pull drive axle out from wheel hub and secure it to body.
- Attach wedge tool - T10161 - between transmission housing and triple roller joint.
- Press inner joint out of transmission via a hammer blow on the wedge tool (T10161).
