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. The cams abut the cam plates and are positioned between pairs of vertically oriented parallel flanges extending from one face of each cam plate. The eccentric mounting of the cams and their captivity between the flanges cause the pin to move linearly within the slots as the pin and cams are rotated. The linear movement of the pin causes a change in the spatial relation between the first end of the control arm and the axle housing. The control arm is attached at a second end thereof to the automobile frame and is inextensible. Therefore, the change in relation between the first end of the control arm and the axle housing translates directly into a change in relation between the axle housing and the frame thereby providing the capability of aligning the axle housing with respect to the automobile frame.
