	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
		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.

4	Remove cover (6f)
5.1	Detach air spring from spring control arm (6)	Vehicles with AIRMATIC (semi-active air suspension), code 489 Do not twist the air spring nor move it into the stretched position as this leads to creases forming in the air spring bellows and consequently to irreparable damage to the air spring. Secure the air spring to prevent it from falling down. Installation:  Do not tighten threaded connection.
5.2	Remove rear spring (6i).	Vehicles without AIRmatic

	Checking
13	Check spring control arms (6) for signs of damage	Vehicles without AIRmatic On vehicles with steel suspension bars are located on the spring control arm (arrow), which shear off at side impacts and thus protect the rear axle carrier (1). If these webs have been sheared off, the spring control arm must be replaced.
14	Check supporting joint (6a) in spring control arm (6) for signs of damage	Vehicles without AIRmatic: Replace supporting ball joint (6a) if necessary: ↓
		Remove/install supporting joint on spring control arm Vehicles with AIRmatic: Replace spring control arm (6) 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.	AR35.20-P-0118R
15	Check rubber mount (6b) for spring control arm (6) in rear axle carrier (1) for signs of damage	Replace rubber mount if necessary.
