	Inspect
1	Observe general information on chassis alignment check.		AR40.20-P-0201A
2	Check vehicle level at front and rear axle with electronic inclination meter and adjust, if necessary		AR40.20-P-0301GH
3	Check camber, match with a value in the table		AR40.20-P-0335-01GH
		Camber at vehicle level	*BE40.20-P-1001-09I
		Permissible rear axle camber between right and left vehicle side	*BE40.20-P-1002-09I
4	Check caster at rear axle using electronic inclinometer	If a repaired supporting joint is installed in the wheel carrier, unscrew locking inner slotted nut with claw-type wrench. Installation: Once used, the locking inner slotted nut must be replaced.	AR40.20-P-0335-03GH

5	Check caster and assign to tabular value		AR40.20-P-0335-02GH
	Adjusting
6	Adjusting camber and caster	The rear axle camber is corrected at the front bolted connection of the top transverse control arm/ vehicle frame. On code 612 Xenon headlamps, detach retaining plate (91c) from vehicle frame and fold to one side with level sensor. The caster is set at the rear bolted connection of top transverse control arm/ vehicle frame.	AR40.20-P-0322-06GH
