	Remove/install
	Notes on self-locking nuts and bolts		AH00.00-N-0001-01A
		Installation: Caution: important note:  It is mandatory for the thread in the frame floor assembly to be recut and blown out, as the remaining adhesive remains in the thread prevent the required preload force of the bolt being reached, despite the specified torque and specified angle of rotation being reached. 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 surfaces of aluminum components do not get any scratches, cracks and notches. Otherwise the service life of the of the parts will be reduced.
		Installation:  Tighten nuts and bolts of chassis components only when vehicle is in the ready-to-drive condition.
