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. Do not tighten threaded connection.
5.2	Remove rear spring (6i).	Vehicles without AIRmatic

			*BA32.25-P-1002-03G
7	Remove shock absorber (6j) from spring control arm (6)	Vehicles with AIRMATIC (semi-active air suspension), code 489 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

	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.
