Drive Axle With CV Joint

Drive Axle with CV Joint

Special tools, testers and auxiliary items required

• Torque wrench (V.A.G 1332)

• Angle wrench (V.A.G 1756)


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 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.

• Twelve-point bolt without ribs, refer to => [ Drive Axle Twelve-Point Bolt without Ribs, Loosening and Tightening ] Drive Axle Twelve-Point Bolt without 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 lower noise insulation.

- Disconnect drive axle from transmission axle flange.

- Remove the wheel.

- Slide outer joint out of wheel hub by hand.

- Remove the nuts - arrows -.






- Remove both the wheel bearing housing and ball joint from the control arm.

- Remove the drive axle from the wheel hub.

Installing

Remove any paint residue and/or corrosion in threads/splines of outer joint.

- Insert outer joint as far as possible into wheel hub splines.

- Attach the ball joint to the control arm - arrows -.






• Make sure that the ball joint boot is not damaged or twisted.

- Install inner joint of drive axle and initially tighten bolts diagonally to 10 Nm.
