Removing

When disassembling and performing repairs on vehicle, the drive axles must not be allowed to hang down and contact the stops in the joint by overflexing.

Removing

- Loosen the drive axle to wheel hub bolt. Refer to one of the following:

=> [ Drive Axle Bolt Loosening and Tightening, Twelve Point Bolt with Ribs ] Drive Axle Bolt Loosening and Tightening, Twelve Point Bolt with Ribs.

The wheel bearing must not be under a load while the drive axle bolt 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 a maximum of 90° when the vehicle is sitting 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 lower noise insulation.

- Disconnect the drive axle from the transmission flange shaft.

- Remove the wheel.

- Slide the outer Constant Velocity (CV) joint out of the wheel hub by hand.

- Remove the ball joint nuts - arrows -.
