Notes on self-locking nuts and bolts

AH00.00-N-0001-01A

 Installation

Caution, important note: The threads in the frame floor assembly must be recut and blown out, as any adhesive residue in a thread will prevent the bolt's necessary preload force from being achieved, despite having reached the specified torque and specified angle of rotation.
If this is not observed, then the faulty bolt preload force will cause bending forces to act on the bolt, which could ultimately lead to bolt fracture.



While working on the rear axle, care must be taken to ensure that the surface of aluminum components do not get any scratches, cracks and notches. Otherwise the service life of the parts will be affected



Only undo the bolts of the front rubber mount (1a) or the rear rubber mount (1b)

 If bolts on the front and rear rubber mount (1a, 1b) are to be jointly undone, then a wheel alignment must be performed, see: 

Perform chassis alignment.
