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.

In a wheel alignment system for a vehicle of a type having a laterally spaced pair of steerable wheels and a laterally spaced pair of unsteerable wheels generally following the steerable wheels, said system including means for displaying on a screen a diagrammatic pictorial representation of the vehicle chassis including all four wheels and a plurality of pictorial diagrams shown in immediate association with each said wheel to respectively display pictorially the status of a corresponding plurality of alignment parameters for each wheel, the last named means displaying an indicator disposed in association with each pictorial diagram for a given wheel, each of said indicators being movable between and beyond upper and lower limits indicated on the screen to show diagrammatically the status of a wheel alignment parameter to be within proper limits or not, said limits being defined to correspond to the vehicle alignment specifications, means for sensing the status of the wheel alignment parameters, and means controlling the analog position of each of said indicators with respect to the limits associated therewith and in response to adjustments made to a wheel associated with the indicator, the last named means displaying digital values associated with the lower and upper limits and of the status of the parameter which is sensed.
