Wheel Alignment Procedure Overview

Wheel Alignment Procedure Overview

Special tools, testers and auxiliary items required

• Steering wheel level (VAS 6458)

• Vehicle must only be measured at curb weight. Refer to => [ Wheel Alignment Test Requirements ] 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 ] Application and ID.

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 ] Steering Rack, Checking Mechanical Center Position.
4 Perform wheel run-out compensation. Refer to => [ Wheel Run-Out Compensation ] Wheel Run-Out Compensation.
5 Check the maximum steering angle. Refer to => [ Maximum Steering Angle, Checking ] Maximum Steering Angle, Checking.
6 Check front axle camber and adjust if necessary. Refer to => [ Front Axle Camber, Checking and Adjusting ] Front Axle Camber, Checking and Adjusting
7 Check rear axle camber and adjust if necessary. Refer to => [ Rear Axle Camber, Adjusting ] Rear Axle Camber, Adjusting.
8 Check rear axle toe and adjust if necessary. Refer to => [ Rear Axle Toe, Adjusting ] Rear Axle Toe, Adjusting.
9 Check the front axle toe angle and adjust if necessary. Refer to => [ Front Axle Toe, Adjusting ] 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 ] 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 ] 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 ] Adjustment Procedure Using ACC Setting Device (VAS 6190), => [ Adjustment Procedure Using ] Adjustment Procedure Using ACC Setting Device (VAS 6430) or => [ Lane Assist Calibration Procedure ] Lane Assist Calibration Procedure.
