FRONT SUSPENSION
DESCRIPTION - FRONT SUSPENSION
This vehicle's front suspension is a short long arm
(SLA) design used in conjunction with a gas pressur-
ized shock absorber and coil spring assembly (Fig. 1).
SLA offers three advantages over the customary
MacPherson strut system for front-wheel-drive vehi-
cles.
• Better handling through geometry that keeps
the tires more perpendicular to the road
• Better noise isolation
• Better ride through reduced friction
The upper control arm of the vehicle is mounted
using rubber isolation bushings to an aluminum cast-
ing which is attached to the shock tower using 4
mounting bolts. This aluminum casting is also used
as the upper mount for the front shock/coil spring
assembly. The shock absorber is isolated from the
aluminum bracket using a microcellular urethane

isolator. The lower control arm is mounted to the
vehicle's front suspension crossmember using 2
through bolts per control arm. The lower control arm
is also isolated from the vehicle using 2 rubber bush-
ings of unique design for the front and rear mounting
location. The bottom of the shock absorber is
mounted to the lower control arm by a clevis bracket
which is part of the shock absorber assembly. The
clevis bracket is mounted to and isolated from the
lower control arm using a rubber isolation bushing
and a through-bolt. The front steering knuckle is
mounted to the vehicle by a ball joint located in the
upper and lower control arms.
A sealed for life front hub and bearing assembly is
attached to the front steering knuckle. The outer C/V
joint assembly is splined to the front hub and bear-
ing assembly and is retained by a nut, nut retainer
and cotter pin.
