Axle Shaft Assembly: Description and Operation

Drive Axle

Lightly coat the splines on the outer joint with assembly paste before installing the outer joint into the wheel hub. Allocation, refer to the Electronic Parts Catalog (ETKA).

Never allow the drive axle just to hang loose under the vehicle or to bend them at the joints.

Wheel bearings must not be burdened when drive axle connection is loose.

If the bearings are loaded by the vehicle's own weight the wheel bearing will be damaged. This reduces the service life of the wheel bearings. Therefore observe the following:

Procedure for loosening the drive axle threaded connection on the wheel side:

• Refer to => [ Drive Axle Hex Bolt Connection, Loosening and Tightening ] Description and Operation.

• Refer to => [ Drive Axle Twelve-Point Bolt with Ribs, Loosening and Tightening ] Drive Axle Twelve-Point Bolt With Ribs, Loosening and Tightening.

• Refer to => [ Drive Axle Twelve-Point Bolt without Ribs, Loosening and Tightening ] Drive Axle Twelve-Point Bolt Without Ribs, Loosening and Tightening.

Tightening the threaded connection between the drive axle and flange shaft:

• First diagonally tighten all six bolts to 10 Nm. Then diagonally tighten them again to the tightening specification.

Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If the vehicle does have to be moved, always note the following points:

- Install an outer joint in place of the drive axle.

- Tighten the outer joint to 120 Nm (twelve-point bolt) or 200 Nm (hex bolt).
