ABSTRACT:
Vehicle wheel alignment apparatus includes a storage device for storing vehicle wheel alignment angle specifications, wheel alignment sensors, and ride height sensors. A controller is responsive to the acquired wheel alignment angle data and to the measured ride height for determining whether, taking into consideration the vehicle ride height, a measured wheel alignment angle falls within specifications. Apparatus for diagnosing vehicle wheel alignment and suspension problems also includes a jack for vertically moving the body of the vehicle with respect to the wheels to temporarily change the ride height of the vehicle. The controller is responsive to changes in measured wheel alignment angles with changes in measured ride height to diagnose vehicle alignment and suspension problems.
