DRIVE AXLE TWELVE-POINT BOLT, LOOSENING AND TIGHTENING
Special tools and workshop equipment required
- Socket XZN 24 T10361
- Angle wrench V.A.G 1756
Wheel bearing must not be burdened while 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. The wheel bearings will be stressed and the life expectancy reduced. Therefore, observe the following
- Procedure for loosening 12-point bolt.
Vehicles without drive axle must not be moved, otherwise 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
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-.
Scheme 1
Tightening
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 vehicle onto its wheels.
Tighten 12-point bolt an additional 90°.

TIGHTENING HOSE CLAMP ON OUTER JOINT
Attach V.A.G 1682 as shown in illustration. Be sure that edges of clamping pliers are seated in corners -arrows B- of hose clamp.
Tension clamp by turning spindle with a torque wrench (do not tilt clamp tool).
Note. A stainless steel clamp must be used due to hardness of CV boot material (compared to rubber). This clamp can only be tensioned using V.A.G 1682. Torque specification: 25 Nm. Use torque wrench -C- with adjustment range 5...50 Nm (e.g. torque wrench V.A.G 1331). Be sure thread of spindle -A- of clamp tool moves freely. Grease with MOS 2 grease if necessary. If it does not move freely, e.g. due to dirt in thread, the required clamp tension will not be achieved at the specified torque.
