Wheel Alignment Procedure Overview
Special Tools And Workshop Equipment Required
- Steering wheel level:VAS 6458
Vehicle must only be measured at curb weight. Refer to WHEEL 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 :VAS 6458 for this.
3 - Steering rack, checking center position, 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 the front axle adjustments have been changed, then is it necessary to calibrate the dynamic steering Refer to DYNAMIC STEERING BASIC SETTING .
11 - If the adjustments to the chassis have been changed, then perform a zero compensation on the steering angle sensor -G85- using the vehicle diagnostic tester.
12 - If the rear axle adjustments have been changed, then is it necessary to calibrate the dynamic steering Refer to DYNAMIC STEERING BASIC SETTING .
13 - If adjustments have been made on the rear axle, calibrate the adaptive cruise control and/or lane assist. Refer to l ADJUSTMENT PROCEDURE USING ACC Setting Device , ADJUSTMENT PROCEDURE USING ACC Setting Device or LANE ASSIST CALIBRATION PROCEDURE .
