Abstract: A multilink suspension assembly for a motor vehicle includes a steering knuckle rotatably mounting thereon a wheel unit, and a tie bar mounted to a respective swivel joint of the steering knuckle. Two lower control links are located aft of the tie bar and have inboard ends mounted to respective mounting junctions on the vehicle chassis and outboard ends mounted to respective swivel joints at a lower end of the steering knuckle. Two upper control links, which are located aft of the tie bar and vertically spaced from the lower control links, have inboard ends mounted to respective mounting junctions on the vehicle chassis and outboard ends mounted to respective swivel joints at an upper end of the steering knuckle. The swivel joints mount the upper and lower control links to the steering knuckle inboard from the wheel unit and below an upper extent of the wheel unit's tire.

Abstract: Control arms used to support a swivel member retaining a wheel of a vehicle are attached to the body or frame rail of the vehicle by U-shaped attachment brackets having walls with lateral slots therein, each of which receives a mounting bolt therethrough. The mounting bolts pass through bushings in the ends of the control arms to pivot the control arms on the vehicle body or frame rail. Adjacent to the heads of the bolts are pairs of reaction surfaces that in one embodiment of the invention are pairs of opposed projecting surfaces on the attachment brackets. Separate tools are provided which have cams thereon each having a first peripheral cam surface for engaging one of the reaction surfaces and a second peripheral cam surface for engaging the other reaction surface. Upon loosening nuts threaded on the mounting bolts and rotating the cams with levers, socket wrench handles or other drives, the bolts shift laterally in the lateral slots enabling adjustment of the camber and caster of the wheels.
