Abstract
A wheel alignment and ball joint wear monitoring system employs a diagrammatic pictorial video display of the chassis of the vehicle being aligned and pictorial diagrams of alignment parameters associated with each of the wheels of the chassis. The region of each wheel when separately enlarged carries a chassis diagram indicating which wheel portion of the diagram has been enlarged. The system permits successive measurements of camber and of toe to be used to determine ball joint wear in the vertical and horizontal planes.
