The front suspension for this vehicle is a combination of a strut assembly and a knuckle assembly. The strut assembly combines a strut dampener and spring mounted to the body of the vehicle. The upper end of the strut is isolated by a rubber mount and contains a bearing to allow the strut to turn. The knuckle is attached to the strut assembly and pivots on a ball joint bolted to the control arm. The control arms pivot from the body using rubber bushings.

The ball joint is fastened to the steering knuckle with a pinch bolt and nut, and to the lower control arm with rivets. The stabilizer bar interconnects both strut assemblies of the vehicle through the stabilizer link and is attached to the front suspension crossmember. Jounce and rebound movements affecting one wheel are partially transmitted to the opposite wheel of the vehicle to stabilize body roll.

When servicing the control arm-to-body attachment and the stabilizer shaft-to-body insulators, ensure the attaching bolts are loose until the control arms are moved to the trim height, which is curb height. Trim height is the normal position to which the control arms move when the vehicle is sitting on the ground.

The springs in the front suspension of engine family II, 1.8L/2.0L, are stronger and the strut dampeners heavier than are the springs and strut dampeners found in the front suspension of engine family I, 1.6L.
