Apparatus for aligning vehicle front and rear wheels and a method of applying such apparatus in which projectors of light beams on the front wheels direct beams forwardly to a cooperating alignment stand and direct beams rearwardly to cooperate with devices on the rear wheels which include scales and reflective surfaces used in aligning the front wheels and determining the positions of the rear wheels relative to the vehicle longitudinal axis or geometric center line. The projectors on the front wheels support screens in positions to cooperate with the light beams when reflected back from the stand and from the rear wheels.
