	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
	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
	Notes on self-locking nuts and bolts	All models	AH00.00-N-0001-01A
1	Lift vehicle with two-post lift	Raise vehicle far enough until the wheels are clear of the ground. Two-post lifting platform 3.0-3.5 t, electromechanical	AR00.60-P-1000RT
2.1	Deflate air spring using the STAR DIAGNOSIS diagnosis system	Only on vehicles with Airmatic (air suspension with level adjustment and Adaptive Damping System ADS), code 489. The wheels must not make any contact with the ground when filling as when filling in the jounce condition the air spring bellows in the spring element will be destroyed. Only deflate air springs, on which the shock absorber mounts are to be removed. Before inflating the air springs start the engine and allow engine to run during inflation process. Ensure air suspension system does not leak.
	Connect STAR DIAGNOSIS and read out fault memory		AD00.00-P-2000-04A
		STAR DIAGNOSIS diagnosis system
3	Switch off ignition and remove the transmitter key from the EIS [EZS] control unit	On vehicles with Keyless Go, code 889: Press Keyless Go start/stop button repeatedly until the ignition is switched off. Remove transmitter key from vehicle and store it in a location beyond its transmission range (at least 2 m).
4	Lift vehicle with two-post lift	Lower vehicles far enough to enable the wheels to be easily accessible. Two-post lifting platform 3.0-3.5 t, electromechanical	AR00.60-P-1000RT
5	Support lower transverse control arm (3) using transmission jack
	Telescopic transmission jack	Transmission jack 2.0-7.0 t
6	Unscrew nut (1)		*BA32.25-P-1001-03L
7	Pull out bolt (2)
8	Lower the lower wishbone (3)	Lower the transverse control arm (3) until the shock absorber mount (4) is accessible.
9	To press out rubber bushing	With the aid of a helper. Removal:  For pressing out, use the spacer E (5) and front press-out sleeve A (6). Press out the rubber mounts to the rear. For pressing in, use the spacer E (5), the press-in block D (7) and the threaded ball (8). Press in the rubber mounts forwards. The cutouts of the press-in block D (7) are seated on the cast seams of the lower transverse control arm (3). During installation the compression on the hand pump must not exceed 140 bar as otherwise the bearing may be damaged.
