HEX BOLT BETWEEN DRIVE AXLE AND WHEEL HUB, LOOSENING AND TIGHTENING
Special tools and workshop equipment required
- Angle wrench V.A.G 1756
Loosening
Scheme 1
With vehicle still standing on its wheels, loosen bolt a maximum of 90°, otherwise wheel bearing will be pre-damaged.
Raise vehicle enough that wheels hang freely.
Operate brake (second mechanic required).
Remove bolt -2-.
Tightening
Replace bolt -2-.
Note. Before installing, clean the threads in the constant velocity joint with a tap. Wheels must not yet touch the ground to tighten the drive axle, wheel bearing may otherwise be damaged.
Operate brake (second mechanic required).
Tighten bolt to 200 Nm.
Lower the vehicle onto its wheels.
Tighten bolt an additional 180°.
12-POINT BOLT BETWEEN DRIVE AXLE AND WHEEL HUB, LOOSENING AND TIGHTENING
Special tools and workshop equipment required
- Socket XZN 24T10361
- Angle wrench V.A.G 1756
The wheel bearing must not be under a load while the drive axle threaded connection on the wheel side 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
Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If vehicle must be moved, observe the following
Install an outer joint in place of the drive axle.
Tighten outer joint to 120 Nm.
Loosening
Scheme 2
With vehicle still resting on wheels, loosen 12-point bolt with T10361 maximum 90°, otherwise, wheel bearing will be damaged.
Raise vehicle enough that wheels hang freely.
Operate brake (second mechanic required).
Remove 12-point bolt -arrow-.
Note. Before installing, clean the threads in the constant velocity joint with a tap.
Fastening
Replace 12-point bolt.
Note. Wheels must not yet touch the ground to tighten the drive axle, wheel bearing may otherwise be damaged.
Operate brake (second mechanic required).
Tighten 12-point bolt to 70 Nm.
Lower the vehicle onto its wheels.
Tighten 12-point bolt an additional 90°.
