WHEEL ALIGNMENT SETTING PROCEDURE - MISINTERPRETATION

Incomplete wheel alignment setting procedure resulting in incorrect wheel alignment.

Cause

Wheel alignment instructions supplied by various wheel alignment equipment suppliers are incomplete. Implications are that ‘run-out’ compensation is not required.

Action


WHEEL ‘RUN-OUT’ COMPENSATION:

The normal wheel setting procedure is to register the alignment equipment measuring head against the wheel rim. However this is not a tightly controlled and toleranced area of the wheel. Any dimensional variation in this area will result in a level of ‘run-out’ relative to the axis of the wheel, causing inaccurate geometry readings which will need to be compensated for. When carrying out wheel alignment checks using ANY type of alignment equipment, ‘run-out’ compensation MUST be carried out. ALWAYS TAKE AN AVERAGE OF 3 READINGS.
