  • Patent number: 6659479
    Abstract: A suspension hanger assembly for receiving the bush end of a control arm is provided for adjusting axle alignment, without vertical displacement, and includes spaced-apart sides; each having aligned bores for a spindle, a bush pin and a fastening bolt. Two cams, having openings for the spindle, bush pin and fastening bolt, are aligned with the bracket bores. The bush pin bore of the bracket is horizontally elongated limiting vertical displacement of the bush pin. The fastening bolt opening of each cam is arcuate-shaped which allows cam actuation in an eccentric pattern. As the cam is moved, the bush pin moves horizontally respective to the bracket. The control arm bush is secured via the bush pin and fastening bolt. The control arm is fixed to the axle and horizontal movement of the control arm within the hanger bracket results in linear movement of that axle respective to the vehicle chassis.
