A vehicle wheel alignment apparatus includes wheel alignment sensors for obtaining wheel alignment data, including camber, and devices for measuring wheel offset distances. A controller compensates the measured wheel offset distances for the camber of the corresponding wheels. Ride height sensors are included for measuring the ride height of the vehicle at the wheels, and the controller also uses the ride height to compensate the wheel offset distances. Ride height is similarly compensated for camber by the controller. The body angle of the vehicle is obtained from the wheel offset measurements and the wheelbase of the vehicle. The body angle is used to compute dog track angles and correct those angles by applying the body angle to the individual toe angles of the reference axle. Axle offsets are computed and used in front axle cradle adjustment if applicable. The body angle is also used to eliminate the effect of wheel offsets from setback angle calculations. The corrected setback angle is converted into a distance when track width is measured.
