The disclosure herein relates to apparatus and method for finding the orientation of a steering pivot axis for a wheel in a pair of steerable wheels in a vehicle suspension system, wherein arbitrary steering directions are imparted to the wheels and measurements are taken of the steering directions and the other steerable wheel alignment characteristics of interest. The measurements are transmitted to a computer which serves to calculate caster, steering axis inclination and the orientation of the steering pivot axis relative to a defined three dimensional alignment coordinate system.
