Work Procedure For Axle Alignment, Overview
NOTE:
The vehicle must only be measured at curb weight position. Refer to TEST REQUIREMENTS .
The Following Sequence of Procedure Steps Must Be Observed.
- 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.
- The steering wheel must be "evened out" into the center position before beginning the measuring and adjusting. Use :VAS6458 for this.
- Perform wheel run-out compensation. Refer to WHEEL RUN-OUT COMPENSATION .
- Check the maximum steering angle. Refer to MAXIMUM STEERING ANGLE, CHECKING .
- Check front axle camber and adjust if necessary. Refer to FRONT AXLE CAMBER, ADJUSTING .
- Check rear axle camber and adjust if necessary. Refer to REAR AXLE CAMBER, ADJUSTING .
- Check rear axle toe and adjust if necessary. Refer to REAR AXLE TOE, ADJUSTING .
- Check the front axle toe and adjust if necessary. Refer to FRONT AXLE TOE, ADJUSTING .
NOTE:
If adjustments were made to the suspension during the axle alignment on vehicles with ESP or ABS, a calibration of the Steering Angle Sensor -G85- must be performed using the Vehicle Diagnostic Tester.
If the rear axle setting was changed, the lane assist must be calibrated on vehicles with lane assist (refer to DRIVER ASSISTANCE SYSTEMS FRONT CAMERA, CALIBRATING ), and on vehicles with a rearview camera system, the rearview camera system must be calibrated. Refer to OVERVIEW - REARVIEW CAMERA SYSTEM .
