Axle Alignment Procedure
Vehicle must only be measured at curb weight. Refer to TEST PREREQUISITES !
Check which suspension is installed in the vehicle. This information can be found on the vehicle data plate. Refer to EXPLANATION OF PRODUCTION CONTROL NUMBERS (PR NUMBER) .
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 :VAS6458 for this.
3 - Checking the steering rack 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, 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 -The dynamic steering must be calibrated if adjustments were made to the front axle settings using the Vehicle Diagnostic Tester. 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 - The dynamic steering must be calibrated if adjustments were made to the rear axle settings Refer to DYNAMIC STEERING BASIC SETTING or Vehicle Diagnostic Tester.
13 - If adjustments have been made on the rear axle, calibrate the adaptive cruise control. Refer to ADAPTIVE CRUISE CONTROL (ACC) and/or LANE ASSIST, CALIBRATING .
