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 from achieving the required preload force, even when tightened to the specified torque and specified angle of rotation.
If this is not observed then the faulty bolt preload force will cause transverse forces to be applied to the bolt, which may cause the bolt to 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

 Installation

Only tighten nuts and bolts of chassis components when vehicle is in a ready-to-drive condition.
