Fig. Fig. 1 Front suspension components

The Citation, Omega, Phoenix and Skylark use a MacPherson strut front suspension design. This is an all-new design, not shared with any other G.M. car. A MacPherson strut combines the functions of a shock absorber and an upper suspension member (upper arm) into one unit. The strut is surrounded by a coil spring, which provides normal front suspension functions.

The strut bolts to the body shell at its upper end, and to the steering knuckle at the lower end. The strut pivots with the steering knuckle by means of a sealed mounting assembly at the upper end which contains a preloaded, non-adjustable bearing.

The steering knuckle is connected to the chassis at the lower end by a conventional lower arm, and pivots in the arm in a preloaded ball joint of standard design. The knuckle clamps to the ball joint stud.

Advantages of the MacPherson strut design, aside from its relative simplicity, include reduced weight and friction, minimal intrusion into the engine and passenger compartments, and ease of service.
