FRONT SUSPENSION

Print

See Figures 1 and 2

The front suspension system is of the MacPherson strut design. The struts used on either side are a combination spring and shock absorber with the outer casing of the shock actually supporting the spring at the bottom and thus forming a major structural component of the suspension.

The wheel hub/steering knuckle is attached to the bottom of the strut. A strut mounting bearing at the top and a ball joint at the bottom allow the entire strut to rotate in cornering maneuvers. The strut assembly, steering arm and the steering knuckle are all combined in one assembly; there is no upper control arm. A rubber bushed transverse link (control arm) connects the lower portion of the strut to the front crossmember via the ball joint; the link thus allows for vertical movement.


CAUTION
Exercise great caution when working with the front suspension. Strut coil springs and other suspension components are under extreme tension and result in severe injury if released improperly. Never remove the nut on the top of the shock absorber piston without using the proper spring compressor tool
