Overview - Wheel Alignment Procedure
Vehicle must only be measured at curb weight, refer to VEHICLE ALIGNMENT TEST REQUIREMENTS !
Check which suspension is installed in the vehicle. This information can be found on the vehicle data plate, refer to PRODUCTION CONTROL NUMBER (PR NUMBER) EXPLANATIONS .
Observe the following work sequence!
1 - Drive the vehicle onto the alignment rack without tension. Move the vehicle back and forth if necessary to relieve any tension on the axle components.
2 - The steering wheel must be "evened out" into the center position before beginning the measuring and adjusting. Use Steering Wheel Scales VAS6458 for this.
3 - Check the center position of the steering rack, refer to STEERING RACK, CHECKING MECHANICAL CENTER POSITION .
4 - Perform wheel run-out compensation, refer to WHEEL RUN-OUT COMPENSATION .
5 - Check the maximum steering angle, refer to MAXIMUM STEERING ANGLE, CHECKING .
6 - Check front axle camber and adjust if necessary, refer to FRONT AXLE CAMBER, CHECKING AND ADJUSTING .
7 - Check rear axle camber and adjust if necessary, refer to REAR AXLE CAMBER, ADJUSTING .
8 - Check rear axle toe and adjust if necessary, refer to REAR AXLE TOE, ADJUSTING .
9 - Check the front axle toe angle and adjust if necessary, refer to FRONT AXLE TOE, ADJUSTING .
10 - If adjustments have been made on the front axle, calibrate the dynamic steering, refer to DYNAMIC STEERING BASIC SETTING and Vehicle Diagnostic Tester.
11 - If adjustments have been made on the suspension, perform a zero adjustment on the Steering Angle Sensor -G85-, refer to Vehicle Diagnostic Tester.
12 - If adjustments have been made on the rear axle, calibrate the dynamic steering, refer to DYNAMIC STEERING BASIC SETTING and Vehicle Diagnostic Tester.
13 - If adjustments have been made on the rear axle, calibrate the adaptive cruise control (ACC) (refer to ADAPTIVE CRUISE CONTROL ) and/or lane assist (refer to CALIBRATION PROCEDURE ).
