	Adjust
1	Check vehicle level at front axle.		AR40.20-P-0302XG
2	Check caster and assign to tabular value.		AR40.20-P-0203XG
3	Replace bolt (2a), washer (2b), adjusting shim (2c) and nut (2d).	Screw on nut (2d) of bolt (2a) up to contact surface, but do not tighten yet. This relieves the elastomer bearing of the lower control arm (1) when rocking the vehicle to settle the suspension. Use adjusting shims with previously-determined values. A change in the position of the bolt (2a) changes the camber. An adjustment of the front lower control arm towards the vehicle center (arrow a) causes a positive camber change (St+). Adjustment of the front lower transverse control arm towards the outside of the vehicle (arrow b) causes a negative camber change (St-). Using different adjusting shims (2c) can misadjust the caster. Adjustment of the lower transverse control arm towards the rear (arrow c) causes a reduction in caster (NL-). Adjustment of the lower transverse control arm towards the front (arrow d) causes an increase in caster (NL+).	AR40.20-P-0263-01XG
4	Check vehicle level at front axle again after camber and caster adjustment.	The vehicle level must correspond to the quoted specified values.	AR40.20-P-0302XG
5	Tighten nut (2d) of bolt (2a) for the camber.	Tighten nut (2d) of bolt (2a) in a ready-to-drive condition. Otherwise, the elastomer bearing will be damaged. Screw/bolt, lower transverse control arm to frame	*BA33.15-P-1009-01A
6	Tighten bolt (2a) for the caster.	Tighten nut (2d) of bolt (2a) in a ready-to-drive condition. Bolt, bearing bracket for transverse control arm at bottom to frame	*BA33.15-P-1010-01A
