DIAGNOSIS
STRUT DAMPENER
A strut dampener is basically a shock absorber. However, strut dampeners are easier to extend and retract by hand than are shock absorbers.

Struts Seem Weak
Checks Check the tire pressures. Check the load conditions under which the vehicle is normally driven. Check the compression and rebound effectiveness of the strut dampener. Action Adjust the tire pressures to the specifications on the tire placard. Consult with the owner to confirm the owner's understanding of normal load conditions. Quickly push down and then lift up on the corner of the bumper nearest the strut dampener being tested. Compare the compression and rebound with those of a similar vehicle that has an acceptable ride quality. Replace the strut dampener, if needed.

Struts Are Noisy
Checks Check the mountings for looseness or damage. Check the compression and rebound effectiveness of the strut dampener. Action Tighten the strut dampener mounting nuts. Replace the strut dampener, if needed. Quickly push down and then lift up on the corner of the bumper nearest the strut dampener being tested. Compare the compression and rebound with those of a similar vehicle that has an acceptable ride quality. Replace the strut dampener, if needed.

Leaks
Checks Check for a slight trace of fluid. Check the integrity of the seal cover on the fully extended strut. Check for an excessive amount of fluid on the strut dampener. Action The strut dampener is OK. Replace the strut dampener. Replace the strut dampener.

BALL JOINT AND KNUCKLE
Ball Joint Inspection
1. 2. 3. 4. 5. Raise the front of the vehicle to allow the front suspension to hang free. Grasp the tire at the top and the bottom. Move the top of the tire in an in­and­out motion. Look for any horizontal movement of the knuckle relative to the control arm. Ball joints must be replaced under the following conditions: S S S S S The joint is loose. The ball seal is cut. The ball stud is disconnected from the knuckle. The ball stud is loose at the knuckle. The ball stud can be twisted in its socket with finger pressure.

Another way to inspect the ball stud for wear is to check the fastener torque at the pinch nut. A loose nut can indicate a stressed stud or a hole in the knuckle boss. Worn or damaged ball joints and knuckles must be replaced.

EXCESSIVE FRICTION CHECK
Use the following procedure to check for excessive friction in the front suspension: 1. Enlist the help of another technician to lift up on the front bumper, raising the vehicle as high as possible. Slowly release the bumper, allowing the vehicle to assume its normal trim height. See "General Specifications" in this section. Measure the distance from the street level to the center of the bumper. Push down on the bumper, release slowly, and allow the vehicle to assume its normal trim height. Measure the distance from the street level to the center of the bumper. The difference between the two measurements should be less than 12.7 mm (0.5 inch). If the difference exceeds this limit, inspect the control arms, the struts, and the ball joints for damage or wear.

2.

3. 4. 5. 6.

Ball Stud Inspection
Make sure to check the tightness of the ball stud in the knuckle boss during each inspection of the ball joint. One way to inspect the ball stud for wear is to shake the wheel and feel for movement of the stud end at the knuckle boss.

GENERAL DESCRIPTION AND SYSTEM OPERATION
FRONT SUSPENSION
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 arm­to­body attachment and the stabilizer shaft­to­body insulators, make sure 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. Refer to "General Specifications" in this section. The springs in the front suspension of engine family II are stronger and the strut dampeners heavier than are the springs and strut dampeners found in the front suspension of engine family I.
