5.5 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 touch‐
ing the end stop when checking the wheel alignment.
• The steering wheel must be “evened out” into the center po‐
sition before beginning the measuring and adjusting. Use
Steering Wheel Scales - VAS6458- for this.
• Vehicle empty weight “Empty weight means: The weight of the
vehicle ready for the road (completely filled fuel tank and wind‐
shield 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
