FRONT SUSPENSION

Print

See Figures 1, 2 and 3

The A-Bodies uses a MacPherson strut front suspension design. The 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 control arm, and pivots in the arm in a preloaded ball joint of standard design. The knuckle is fastened to the ball joint stud by means of a castellated nut and cotter pin.

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.

When removing any steering components, it is advisable to matchmark (scribe) the locations of the components
