FRONT SUSPENSION
STABILIZER BAR (Continued)
INSTALLATION
INSTALLATION - STABILIZER BAR
(1) Position stabilizer bar and bushings as an
assembly into front crossmember. Install the stabi-
lizer bar bushing retainer to crossmember and body
attaching bolts (Fig. 57).
(2) Tighten the bushing retainer attaching bolts to
a torque of 61 N·m (45 ft. lbs.).
(3) Align stabilizer bar attaching link assemblies
with attaching link mounting holes in the lower con-
trol arms. Install stabilizer bar attaching links into
both lower control arms. Install the attaching link to
lower control arm retaining nuts. Torque the stabi-
lizer bar attaching link nuts to 101 N·m (75 ft. lbs.).
INSTALLATION - STABILIZER BAR BUSHING
(1) Install new stabilizer bar bushings on the sta-
bilizer bar. Bushings must be installed on sway
bar with slit in bushing facing front of vehicle
when sway bar is installed.
(2) Install bushing retainers back on stabilizer bar
bushings.
UPPER BALL JOINT
DESCRIPTION
The ball joint is pressed into the upper control arm
and has a tapered stud for attachment to the steer-
ing knuckle. The ball joint stud is attached and
locked into the steering knuckle using a special nut.
The ball joint is a sealed-for-life type and requires no
maintenance. If the ball joint is defective it will
require replacement of the entire upper control arm.
DIAGNOSIS AND TESTING - UPPER BALL
JOINT
(1) Raise and support vehicle so that tires clear
floor. (Refer to LUBRICATION & MAINTENANCE/
HOISTING - STANDARD PROCEDURE)
(2) Push inward and pull outward at top of tire
noting if any movement of ball joint occurs.
(3) If movement is noted, replace upper control
arm.
ALTERNATE METHOD
(1) Raise and support vehicle. (Refer to LUBRICA-
TION & MAINTENANCE/HOISTING - STANDARD
PROCEDURE)
(2) Remove tire and wheel assembly. (Refer to 22 -
TIRES/WHEELS - REMOVAL)
(3) Push inward and pull outward on neck of
knuckle near ball joint while observing ball joint for
movement. Holding a finger against knuckle and
upper control arm while performing this helps to
sense movement.
(4) If movement is noted, replace upper control
arm.
UPPER CONTROL ARM
DESCRIPTION
The upper control arm is a high strength steel
stamping. The upper control arm uses the 2 rubber
bushings of the upper control arm/shock absorber
mounting bracket to isolate it from the mounting
bracket and the body of the vehicle. The upper con-
trol arm is bolted to the top of the steering knuckle
through the upper ball joint.
If damaged, the upper control arm is serviced only
as a complete component. Inspect the upper control
arm for any signs of damage. If control arm shows
any sign of damage the upper control arm must be
replaced. Do not attempt to repair or straighten a
broken or bent upper control arm.
OPERATION
The upper control arm supports the upper end of
the steering knuckle and allows for the up and down
movement of the suspension during the jounce and
rebound travel.
