ABSTRACT:
Undesired deviations in wheel angle measurements caused by compression forces inherent in alignment operations are corrected. A vehicle wheel is placed in a particular orientation both before and after an alignment procedure, and respective angle measurements are taken each time. Any difference in these angle measurements must be the result of an undesired deviation. Such deviation quantities may then be monitored by an operator or compensated during subsequent angle measurements by a computer alignment system.
