ML 320 (163.154) V6-3.2L (112.942) (1998)
Checking and Adjusting:
1. Fix steering wheel in center position. Install holding device (055) for this. (Special Tool 129589012100)
2. Check center position of steering gear and the steering wheel. The steering gear is in the center position if the marking line on the cap aligns with
the marking notch on the rotary disc valve (arrow). If necessary offset steering wheel by a maximum of 1 tooth.
3. Adjust toe-in by loosening lock nut (10f) and rotating the tie rods (10). Check bellows for twisting after adjusting toe-in.

Check toe-out on turns
NOTE: To check steering geometry measure toe-out on turns. This is the difference in the wheel angle between the wheel on the outside of a
curve and the wheel on the inside of a curve when the wheel on the inside of the curve is turned 20 degrees. Greater deviations may be caused as
follows whereby it is assumed that camber and caster are adjusted correctly:
1. Toe-in not adjusted with steering gear in straight ahead position resulting in unequal tie rod lengths.
2. Steering knuckle, steering column or steering intermediate arm bent.
3. On vehicles involved in an accident excessive deviations in the front end (longitudinal frame member, frame cross member, wheelhouse and
firewall, or on front axle carrier) which have a negative effect on the adjustment range for camber and caster can result in greater differences in
the toe-out on turns between left and right.
