Abstract: A tool is provided for continuously and concurrently monitoring both caster and camber during realignment of wheels on an automotive vehicle. The tool includes a fitting which couples to the spindle for a wheel of an automotive vehicle and a degree gauge mounted on the fitting which is adjustable for horizontal alignment in a plane perpendicular to the spindle. A conventional camber gauge is coupled to the fitting so that camber can be observed on the conventional camber gauge and caster can be observed on the tool of the invention while effectuating realignment of the spindle. The tool of the invention allows caster to be monitored without the necessity of keeping a vehicle on an expensive wheel alignment rack and without the expense of electronic or computerized alignment equipment. By reducing the time required for occupancy of a wheel alignment rack, the wheels of more vehicles can be realigned in a much shorter period of time than has heretofore been possible.
