Checking Requirements

Checking Requirements
^ Test equipment must be properly adjusted and attached to vehicle (refer to equipment manufacturer's instructions)
^ Equal tread depth for both tires on each axle, with difference between two not more than 2 mm (0.079 inch)
^ Tires inflated to correct pressure
^ Sliding plates and turntables not positioned against any stop when checking wheel alignment
^ Vehicle at correct curb weight (1)
^ Vehicle accurately positioned, suspension bounced and rocked several times and allowed to settle
^ Suspension, steering and steering linkage in proper condition with no damage or excessive play
^ Carry out axial wheel run-out compensation. Since some wheel run-out is allowable, checking alignment without first compensating for axial wheel run out may indicate that the toe-in tolerance is already exceeded. If this is the case it is not possible to set toe-in without first compensating for wheel run-out

(1) Curb weight is defined as: the weight of the vehicle ready for the road (fuel tank completely full, spare wheel, vehicle tool kit and vehicle jack all in specified positions).

Wheel alignment must be checked if:





^ There are problems with vehicle performance.
^ There is accident damage.
^ Tires are worn on one side.
^ Axle components have been removed (see provided table).
