Abstract: A method of aligning the rear suspension of an automobile is practiced in connection with an apparatus for adding linear adjustability to the pivotal connection between the lower control arms and the rear axle housing of an automobile. The linearly adjustable connection comprises a pair of cam plates adapted to be affixed to opposite sides of a rear axle housing bracket. The first end of the lower control arm is installed in the rear axle housing bracket intermediate the cam plates and a threaded pin is inserted through aligned elongate slots formed in the cam plates and housing bracket to hold the lower control arm in position with respect to the rear axle housing. The elongate dimension of the slots is oriented parallel to the fore/aft axis of the automobile. A pair of circular cams are eccentrically mounted on the threaded pin in such a manner that they move in unison with the pin.
