	Remove/install
	Risk of death caused by vehicle slipping or toppling off of the lifting platform.	Align vehicle between columns of vehicle lift and position four support plates at vehicle lift support points specified by vehicle manufacturer.	AS00.00-Z-0010-01A
	Notes on self-locking nuts and bolts		AH00.00-N-0001-01A
	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 pretension 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
	Only undo the bolts of the front or rear rubber mounts. If the bolts of the front and rear rubber mounts are undone together, chassis alignment will have to be performed
	Only tighten nuts and bolts of chassis components when vehicle is in a ready-to-drive condition.
