a torch sometimes helps too, but isn't recom-
mended because of the obvious fire dangers.
Long breaker bars and extension, or
"cheater," pipes increase leverage, but never
use an extension pipe on a ratchet - the
ratcheting mechanism could be damaged.
Tightening the nut or bolt first will sometimes
help break it loose. Fasteners that require
drastic measures to remove should always
be replaced with new ones.
Most of the procedures in this Chapter
involve jacking up the vehicle and working
underneath it. A good pair of jackstands will
be needed. A hydraulic floor jack is the pre-
ferred type of jack to lift the vehicle, and it
can also be used to support certain compo-
nents during various operations. Warning:
Never rely on a jack to support a vehicle while
working on it. Whenever any of the suspen-
sion or steering fasteners are loosened or
removed they must be inspected and, if nec-
essary, replaced with new ones of the same
part number or of original equipment quality
and design. Torque specifications must be
followed for proper reassembly and compo-
nent retention. Never attempt to heat or
straighten any suspension or steering compo-
nents. Instead, replace any bent or damaged
part with a new one.

(front) - removal, inspection and
installation
Removal
Refer to illustrations 2.2a, 2.2b and 2.3
1
Loosen the front wheel lug nuts, raise
the front of the vehicle and support it
securely on jackstands. Apply the parking
brake and block the rear wheels to keep the
vehicle from rolling off the stands. Remove
the front wheels.
2
Remove the nuts and the stabilizer bar
attaching link assemblies from the front lower
control arms (see Illustrations). Note: Use
an Allen wrench in the end of the lower con -
trol arm stud to prevent the stud from moving
when removing the attaching link nut.
3
Remove the four bolts attaching the sta-
bilizer bar bushing clamps to the front sus-
pension crossmember and body (see illus-
tration).
4
Remove the stabilizer bar from the vehi-
cle.
Inspection
5
Inspect for cracked, torn, or distorted
stabilizer bar bushings, bushing retainers,
and worn or damaged stabilizer bar attaching
li nks. Damaged stabilizer bar attaching links
must be replaced before reinstalling the sta-
bilizer bar.

To replace damaged stabilizer bar bush-
ings, open the bushing slit and peel the bush-
ing from the stabilizer bar. Caution: Install the
new bushings with the slits facing the same
way that the original bushing slits faced.

Shock absorber/coil spring -
replacement
Warning: Disassembling a shock absorb-
er/coil spring assembly is dangerous. Use
only a high-quality spring compressor, which
can be rented at most auto parts stores or
equipment yards. Carefully follow all instruc-
tions furnished by the tool manufacturer or
serious injury could result.
Disassembly
Refer to illustrations 4.2, 4.6, 4.7, 4.8 and
4.10
1
Remove the shock absorber assembly
(see Section 3).
2
Reinstall the clevis bracket on the shock
absorber and tighten the pinch bolt. Clamp the
shock absorber in a vertical position in a vise
holding the clevis bracket (see illustration).
3
Compress the coil spring using a coil
spring compressor (which can be obtained at
most auto parts stores or equipment yards).
Follow the tool manufacturer's instructions,
install the spring compressor on the spring,
and compress it sufficiently to relieve all
pressure from the upper spring seat. Warn-
ing: Do not remove the shock absorber
damper rod nut before the coil spring is com-
pressed. Be sure to have the first full top and
bottom coil of the coil spring captured by the
coil spring compressor.
4
Remove the shock absorber damper rod
nut while holding the rod to prevent it from
rotating.
5
Remove the damper rod washer, the
upper control arm mounting bracket and the
isolator bushings from the damper rod.
6
Mark and remove the shock absorber
upper isolator bushing, and the lower isolator
bushing and sleeve from the upper control
arm mounting bracket. Then remove the
upper spring isolator from the mounting
bracket (see illustration).
7
Remove the lower isolator bushing from
the damper rod sleeve (see illustration).
8
Remove the washer from the top of the
dust shield and the dust shield from the
shock absorber assembly (see illustration).
9
Remove the compressed coil spring.
Warning: Keep the ends of the spring
pointed away from your body. Set the spring
aside in a safe, isolated location. Note: Mark
the springs R or L for proper reinstallation.

ing and other signs of deterioration. If neces-
sary, take the control arm to an automotive
machine shop to have the bushings replaced.
Installation
15 Install the rear, and then the front of the
lower control arm into the front suspension
cradle. Do not tighten the bolts at this time.
16
Connect the lower balljoint to the steer-
ing knuckle, tightening the castle nut to the

Install a new cotter pin.
17 Installation of the remaining compo-
nents is the reverse of removal. Caution: Be
sure to install the balljoint heat shield. If the

due to excessive heat from the brake disc.
18
After installing the clevis on the lower
control arm, place a floor jack under the
lower balljoint and raise the lower control arm
to simulate normal ride height. Tighten the
lower control arm-to-crossmember bolts and
the shock absorber clevis-to-lower control
arm bolt/nut to the values listed in this Chap-
ter's Specifications.

Balljoints (front) - check
1
With the vehicle on the ground, reach
around the tire and try to wiggle the balljoint
grease fitting. If any movement is felt, the
balljoint is worn out.
2
Raise the vehicle and support it securely
on jackstands. Make sure the tires are not
contacting the ground.
3
Grasp the tire at top and bottom and try
to rock it in and out. Have an assistant feel for
play in the balljoints while you do this. The
balljoints on these vehicles are not supposed
to have any freeplay, so if any movement is
evident, the balljoint must be replaced.
4
The balljoints on these vehicles are not

serviceable, nor can they be removed from
the control arms. If a balljoint is bad, replace
the control arm (see Section 5).
5
The balljoint seal, however, is replace-
able. This is done by prying the old seal off
and pressing a new one into place with a
socket large enough to contact the outer cir-
cumference of the seal.
