ABSTRACT:
The method of the present invention includes the steps of locating a single point on the wheel, rotating the wheel about its central axis of rotation, tracking the position of the single point in three dimensional space while the wheel is in a natural loaded driving condition and generating a signal directly representative of the actual rotational plane of the wheel. The generated signal may then be compared to an electronically stored mathematical model to determine wheel alignment conditions. The method of the present invention may be conducted on all four wheels simultaneously by separate tracking units each operatively positioned to track a single wheel.
