	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
		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 parts will be affected
		Installation: Only tighten bolts and nuts of the chassis components when in ready-to-drive condition.
1	Empty air spring (6i) completely using STAR DIAGNOSIS		AR32.22-P-1500-04TA
	Notes on air suspension		AH32.22-P-1000-01T
		Installation: The filling procedure for the air springs must be observed, otherwise the air springs will be irreparably damaged.	AR32.22-P-1500-03TA

3	Remove rear wheel
	Remove/install wheels, rotate if necessary		AP40.10-P-4050Z
4	Remove cover (6f)
5	Detach air spring (6i) from spring control arm (6)	Do not twist the air spring and do not move into the stretched position as this leads to creases forming in the air spring bellows and consequently to irreparable damage to the component. Secure the air spring to prevent it from falling down.
		Installation: Do not tighten threaded connection.
6	Detach shock absorber (6j) from spring control arm (6).		*BA32.25-P-1002-03G
7	Remove shock absorber (6j) from spring control arm (6)	Push together shock absorber and position at side of spring control arm.
8	Raise wheel carrier (7) with transmission jack and transmission platform until the rear axle shaft (37) is approximately horizontal	Installation: Tighten all bolted connections which are screwed together loosely
			*BA35.20-P-1001-04C
			*BA35.20-P-1003-01A
9	Detach tie rod (4) from wheel carrier (7) and swing upwards.	Installation: Mount bolted connection loosely.
10	Pull off protective cap (31k) and unscrew lower guide bolt (31c) for brake caliper		*BA42.10-P-1003-12H
11	Detach spring control arm (6) from rear axle carrier (1).	Installation: Mount bolted connection loosely.
12	Detach spring control arm (6) from wheel carrier (7) and lever out spring control arm (6).	Installation: Drive fitted bush (7b) flush into wheel carrier (7) using a suitable tool.

	Checking
13	Check supporting joint (6a) in spring control arm (6) for signs of damage	Replace spring control arm if necessary. In the case of aluminum spring control arm for air suspension the supporting ball joint must not be replaced. The spring control arm is damaged by the supporting ball joint being pulled out and in. An exact alignment of the spring link halves is not subsequently possible.
14	Check rubber mount (6b) for spring control arm (6) in rear axle carrier (1) for signs of damage	Replace rubber mount if necessary.
