DRIVE AXLE HEX BOLT CONNECTION, LOOSENING AND TIGHTENING
Special tools and workshop equipment required
- Angle Wrench V.A.G 1756
Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If vehicle does have to be moved, always note the following points
Install an outer joint in place of the drive axle.
Tighten outer joint to 200 Nm.
Loosening
Scheme 21
With the vehicle resting on its wheels, loosen the bolt -arrow- maximum 90° otherwise the wheel bearing will get damaged.
Lift the vehicle just enough so that the wheels are hanging free.
Apply the brakes (a second technician required).
Remove hex bolt -arrow-.
Note. Before installing, clean the threads in the CV joint with a tap.
Tightening
Replace hex bolt.
Note. Wheels must not yet touch the ground to tighten the drive axle, wheel bearing may otherwise be damaged.
Apply the brakes (a second technician required). Tighten hex bolt to 200 Nm.
Lower the vehicle onto its wheels.
Turn bolt an additional 180°.
DRIVE AXLE TWELVE-POINT BOLT WITH RIBS, LOOSENING AND TIGHTENING
Special tools and workshop equipment required
- Socket XZN 24 T10361
- Angle Wrench V.A.G 1756
Characteristics between a Twelve-Point Bolt with Ribs and a Twelve-Point Bolt without Ribs
Scheme 22
The contact surfaces -arrow A- and -arrow B- are different on the two-point bolts.
I - twelve-point bolt with ribs -arrow A
II - twelve-point bolt without ribs -arrow B
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
- Procedure for loosening 12-point bolt.
Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If the vehicle does have to be moved, always note the following points
Install an outer joint in place of the drive axle.
Tighten outer joint to 120 Nm.
Loosening
With the vehicle still resting on wheels, loosen 12-point bolt -arrow- with T10361 maximum 90° otherwise the wheel bearing will get damaged.
Lift the vehicle just enough so that the wheels are hanging free.
Apply the brakes (a second technician required).
Remove 12-point bolt -arrow-.
Note. Before installing, clean the threads in the CV joint with a tap.
Tightening
Replace 12-point bolt.
Note. Wheels must not yet touch the ground to tighten the drive axle, wheel bearing may otherwise be damaged.
Apply the brakes (a second technician required).
Tighten 12-point bolt to 70 Nm.
Lower the vehicle onto its wheels.
Tighten 12-point bolt an additional 90°.
