Vehicle Alignment Test Requirements

Vehicle Alignment Test Requirements

• Tread depth difference may be no more than 2 mm on an axle.

• Tires inflated to prescribed pressure.

• 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.

• Make sure that the sliding plates and turn tables are not touching the end stop when checking the wheel alignment.

• The steering wheel must be "evened out" into the center position before beginning the measuring and adjusting. Use steering wheel scales (VAS 6458) for this.

• Vehicle empty weight "Empty weight means: The weight of the vehicle ready for the road (completely filled fuel tank and windshield washer fluid reservoir, spare tire, vehicle tool kit, vehicle jack) and with no driver."

Spare wheel, vehicle tools and vehicle jack must be located in the position specified by the vehicle manufacturer.

• Vehicle accurately aligned, suspension bounced and rocked several times

• Check suspension, steering and steering linkage for excessive play and damage, repair if necessary.

• Perform wheel run-out compensation: Permissible axial run-out of the wheel rims can exceed the specified toe setting tolerance. If compensation for wheel run-out is not performed, it will not be possible to obtain a correct toe-in adjustment.
