A wheel alignment system measures caster and steering axis inclination (SAI) by positioning the wheels at a right turn position and a left turn position. Toe, camber and inclination angle measurements are made for both wheels at both the left turn position and the right turn position. Based upon these measurements, caster and SAI are calculated either directly or through an iterative technique.

A method for accurately measuring caster and steering axis inclination (SAI) of left and right steerable wheels of a vehicle based upon measurements taken with the wheels in less than four different positions, the method comprising: mounting a left head unit on the left steerable wheel of the vehicle; mounting a right head unit on the right steerable wheel of the vehicle; turning the wheels to a first position; making toe, camber and inclination angle measurements for each of the wheels with the left head unit and the right head unit while the wheels are in the first position; turning the wheels to a second position; making toe, camber and inclination angle measurements for each of the wheels while with the left head unit and the right hand unit while the wheels are in the second position; and calculating caster and SAI of each wheel using the toe, camber and inclination angle measurements made for that wheel at the first and second positions.
