Adjust track and camber
Adjustment of camber/track on wishbone
Diagram dependency of track/camber adjustment
(For printing out and entering values)
Through the turning of the eccentric screws (setting of camber and track), the vehicle ride height can change. For the exact setting of the camber and track, the automatic ride height measurement should be activated in the wheel alignment equipment when available.
Turning the adjustment screw on the camber control arm or on the wishbone always results in a change in the camber and track values! Separate camber or toe adjustment is no longer possible!
Check the alignment of the active cruise control (ACC) after an adjustment on the rear axle that changes the driving axis.
Preliminary work
- Refer to PROCEDURE FOR TOE AND CAMBER ADJUSTMENT IN THE DESIGN POSITION .
- Refer to PROCEDURE FOR ADJUSTING TRACK/CAMBER FOR RIDE-HEIGHT-DEPENDENT MEASUREMENT (UNLOADED) .
Turning the eccentric bolts to adjust toe and camber may change the vehicle ride height. When replacing the screws, make sure the eccentric bolts are correctly positioned to keep the change in vehicle ride height during the adjustment work to a minimum.
- Raise vehicle.
- Replace the eccentric screws (1) and (2) including nut and eccentric washers before setting and join with 5 Nm.
Parts: Eccentric screws, nuts, eccentric washers
- When replacing them, position eccentric screws (1) and (2) in such a way that the eccentric is positioned vertically towards.
- Adjusting on wishbone:
Turn the eccentric screw (2) until the intermediate setting is in place.
Tighten nut (1).

Follow-up work
- Adjusting the front radar sensor (FRS).NOTE: TECHNICAL INFORMATION
Notes on the adjustment of the ACC sensor are a fundamental requirement for these repair instructions and must be complied with at all times.NOTE: TECHNICAL INFORMATIONIf there is a "Sensor misadjusted" fault memory entry" and a correct sensor alignment using the adjustment screw is not possible, there is a suspicion of front impact damage.
In this case, the vehicle must be carefully inspected for damage. If necessary, damaged parts must be replaced. Then adjust the ACC sensor again.
A damaged / bent holder indicates a mechanical misuse of the vehicle and will not be considered to be a warranty case.
Checking the vehicle and components for damage.
Check
- In the visible areas, precise visual inspection of:
- damage
- deformation
Result
