Loosening and tightening hexagon bolt securing drive shaft > < Drive shafts
General notes:
General notes:
When working on the vehicle, do not allow the drive shafts to hang down under their own weight and never let the joints bend to such an extent that they contact the end stop.
Wheel bearings must not be subjected to load after loosening bolt securing drive shaft at wheel hub.
If the wheel bearings are subjected to the full weight of the vehicle they will be overloaded, resulting in reduced service life. Therefore please note the following:
t  → Chapter „Loosening and tightening hexagon bolt securing drive shaft“.
t  → Chapter „Loosening and tightening twelve-point ribbed bolt securing drive shaft“.
Do not attempt to move the vehicle without the drive shafts fitted; this would result in wheel bearing damage. If the vehicle does have to be moved, always note the following points:
–  Fit an outer joint in place of the drive shaft.
–  Tighten outer joint to 120 Nm (twelve-point bolt) or 200 Nm (hexagon bolt).
Procedure for tightening bolts securing drive shaft to flange shaft:
t  First pre-tighten all 6 bolts in diagonal sequence to 10 Nm, then tighten in diagonal sequence to final specified torque.
Before fitting the outer joint in the wheel hub, apply a thin coat of assembly paste to the splines on the outer joint → Electronic parts catalogue.
Always renew self-locking bolts/nuts.
Always renew bolts and nuts which are tightened by turning through a specified angle.
