 Danger!

Risk of injury caused by body parts being jammed or crushed. Risk of injury to skin and eyes caused by brake fluid spraying out at high pressure when working on the SBC brake system

Deactivate SBC brake system using STAR DIAGNOSIS.

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 the bolts of the front and rear rubber mounts (1a, 1b) are released together, a wheel wheel alignment check must be performed: 

Perform chassis alignment.

AR40.20-P-0200TX

 Installation

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