Ball Joint

Special tools, testers and auxiliary items required

• Ball Joint Puller (3287A)

• Torque Wrench 40-200 Nm (V.A.G 1332)

• Engine/Gearbox Jack (V.A.G 1383 A)

• Digital Torque Wrench (V.A.G 1756)

Removing

- Loosen drive axle bolt to wheel hub. Refer to => [ Drive Axle Twelve-Point Bolt, Loosening and Tightening ] Service and Repair.

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.

- Loosen the wheel bolts.

- Raise the vehicle.

- Remove the wheel.

- Pull the drive axle slightly off the wheel hub.

- Remove the control arm from the ball joint.

- Move the control arm downward as much as needed.

- Loosen the nut on the ball joint - 2 - but do not remove it.






To protect thread, screw nut on pin a few turns.

- Remove the ball joint from the wheel bearing housing. Then remove the nut and the ball joint - 2 -.
