REMOVINGINSTALLING Remove/install     
1 Secure vehicle on vehicle lift   AR00.60-P-0100EWS
2 Remove left or right rear wheel    
REFER TO MAINTENANCE     AP40.10-P-4050EW
3 Support rear axle carrier (1) using telescopic lifter and transmission plate Transmission jack
Transmission platform
 
4 Unscrew nut (3m) from left or right underfloor paneling (3)    
5 Pull down underfloor paneling (3) in rear area far enough to gain access to the thrust arm mounting (5) on the rear axle carrier (1)    
6 Unscrew bolt of left and right rear diagonal strut on bracket for stop plate (2) MODEL 212.2, 218.9  
TORQUE SPECIFICATION Bolt, rear diagonal strut bracket mount to body *BA61.10-P-1006-01H 
7 Unscrew bolts (1a, 2a) and remove stop plate (2) INSTALLATION NOTES
The threads in the frame floor assembly must be recut and blown out as any adhesive residue in the thread will prevent the bolts (1a, 2a) 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 bending forces to act on the bolts (1a, 2s), which could ultimately lead to bolt fracture.
INSTALLATION IMPORTANT Replace bolts (1a, 2a).
 
TORQUE SPECIFICATION Self-locking bolt of front elastomer bearing on rear axle carrier to frame floor assembly *BA35.10-P-1001-01N 
TORQUE SPECIFICATION Bolt, stop plate to body *BA35.10-P-1003-01N 
8 Remove thrust arm (5) from rear axle carrier (1) and wheel carrier (7) INSTALLATION IMPORTANT Only tighten nuts and screws/bolts of suspension components when vehicle is in a ready-to-drive condition.
