Drive Axle, Triple Roller Joint AAR2600i and AAR3300i, Mounted in Transmission

Special tools, testers and auxiliary items required

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

• Wedge Tool (T10161)

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.

=> [ Drive Axle Bolt Loosening and Tightening, Twelve Point Bolt without Ribs ] Drive Axle Bolt Loosening and Tightening, Twelve Point Bolt without 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 wheel.

- Remove the lower noise insulation.

- Remove the ball joint nuts - arrows -.






- Separate the ball joint from the control arm.

- Pull the drive axle out from wheel hub and secure it to the body.

- Insert the wedge tool (T10161) between the transmission housing and the joint piece.






- Pry the inner joint piece out of the transmission via a strike on the wedge tool (T10161) from a hammer.

- Remove the drive axle.

Installing

- Insert a new circlip into the groove on the joint piece.

- Position the outer spline of the joint piece with the inner splines of the transmission.

- Grasp the drive axle by hand and push the joint piece into the transmission up to the stop.

- Now, with a quick pushing motion, insert the joint piece into the transmission.

The slide path in the joint piece can be used for this pushing motion. When doing this, do not pull the drive axle too far out of the joint.

• Do not use a hammer or other type of knocking tool under any circumstances!

- Check the drive axle for secure fitting in the transmission by pulling the joint piece against the resistance of the circlip.

For this check, do not pull on the drive axle its self, but rather only on the joint piece.

- Insert the outer Constant Velocity (CV) joint as far as possible into the wheel hub splines.

- Install the lower noise insulation.

- Install the ball joint to the control arm and install the nuts - arrows -.






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

- Tighten 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.

=> [ Drive Axle Bolt Loosening and Tightening, Twelve Point Bolt without Ribs ] Drive Axle Bolt Loosening and Tightening, Twelve Point Bolt without Ribs.

The vehicle must not rest on its wheels when doing so.

With the bolt loosened, the wheel bearing can be damaged by the vehicle weight.
