Vehicle Alignment Overview

Special tools, testers and auxiliary items required

• Steering Wheel Sales (VAS 6458)

• Vehicle must only be measured at curb weight. Refer to => [ Test Prerequisites ] Test Prerequisites!

• Check which suspension is installed in the vehicle. This information can be found on the vehicle data plate. Refer to => [ Explanations of the Production Control Numbers (PR number) ] Description and Operation.

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.
