	Inspecting
1.1	Check vehicle ride height at front and rear.	Use Mercedes-Benz test device	AR40.20-P-0300A
1.2	Check vehicle level at front and rear axle with electronic inclination measuring instrument and adjust, if necessary	Model 202, 208 With electronic inclination monitor	AR40.20-P-0301A
		Model 203	AR40.20-P-0301P
2	Inspect oil level of level control.	With electronic inclination measuring instrument
3	Pull the rear of the vehicle down to the specified reference point (simulated load) and position the test device (02) against the inside of the track control arm.		*BE40.20-P-1001-04A
		*BE40.20-P-1002-04A
		Position the angle iron (040i) at the rear subframe bushing and secure with a retaining pin.	Fig 2
		Attach chains from puller in the angle iron (040i).	Figure
		Chains	Fig 4
		Use sensor arm to scan position of rear halfshaft.	Figure
	Adjusting
4	Insert, extract 4 mm drift (015) through the socket (arrow) in the control module's (3) adjustment lever (3a).	When the adjustment is correct the drift can be inserted in the alignment socket in the suspension-control module. Incorrect adjustment of linkage rod (55a) ↓. Loosen the lock-nuts and use the adjustment screw to lengthen or shorten the linkage rod, continuing until the lever on the suspension-control module (3a) can be held in position against the module itself using the 4 mm drift (arrow).
