S 600 Coupe (140.076) V12-6.0L (120.982) (1997)
NOTE: Numbers in parentheses ( ) indicate a component or tool in the associated illustration.
INSPECTION
1. Follow Sequence of Steps For Performing Alignment
2. Check vehicle level at front axle and rear axle. See: Suspension/Adjustments
3. Install measuring device tool No. 140 589 03 21 00, or equivalent, for caster (04) in the fixing points on the steering knuckle.
4. Check camber and caster.
ADJUSTMENT
Adjust camber (front cam bolt, 19) and caster (rear cam bolt, 20) at the wishbone mount.
NOTE:
^
The wheel spreader must not be used to adjust the toe-in.
^
If the specified value of camber or caster cannot be adjusted check upper wishbone, steering knuckle and body for accident damage and the
supporting joints and follower joints for wear.

Check Front Toe Angle Differential
INSPECTION
1. Check and adjust toe-in at front axle
2. Checking toe-out on turns
NOTE:
^
Toe-out on turns is measured to check the steering geometry.
^
This is the difference in wheel steer angle between the wheel on the outside of the curve and the wheel on the inside of the curve when the
wheel on the inside of the curve is steered through 20°.
^
Greater deviations may be due to the following causes, assuming that the camber and caster are correctly adjusted.
a. Toe-in not adjusted in the straightahead position of the steering gear so that the track rod lengths are uneven.
b. Steering knuckle arm, pitman arm, or steering idler arm distorted.
c. Excessive deviations at the front end on vehicles involved in accidents (frame longitudinal member, frame crow member, wheelhouse and
firewall or on the front axle carrier) which have an adverse effect on the range of adjustment for amber and caster so that large differences
in toe-out on turns result between the left and right.
SPECIFICATIONS
