A system used for alignment of a vehicle suspension and axle includes a pear-shaped cam that is rotatable relative to one of two spaced plates of a hanger bracket. An aperture and nose in the cam plate is aligned with an elongated opening in the bracket plate. The cam further includes a pin that is configured for insertion and movement within an arcuate aperture in the bracket plate. A fastener extends through the aperture and the nose of the cam, through the elongated openings in the bracket plates, and through the suspension control arm. Rotation of the cam causes a corresponding movement of the pin along the arcuate-shaped aperture of the bracket and of the fastener along the elongated openings of the bracket.
