Abstract: A tool arranged for the testing of automotive components, such as ball joints, is provided to include a handle pivotally mounted to an "L" shaped positioning leg. The positioning leg includes an upper cylinder mounted to the leg to receive a stud portion of a ball joint therethrough, with the lower cylindrical member defining a cup to receive a lowermost portion of a ball joint therewithin to permit pivotment of the "L" shaped leg relative to a handle pivotally mounted through the "L" shaped leg indicating deflection of a ball joint when the handle is pivoted relative to the "L" shaped leg. A modification of the invention includes magnetic insert members, each including parallel support legs to receive opposing ends of a shock absorber such as a gas-filled shock absorber to indicate resistance and deflection of the shock absorber in use.
