(9) Using same bolt or identical replacement bolt,
mount tone wheel to hub and bearing. Tighten bolt to
17 N·m (13 ft. lbs.) torque.
(10) Install brake rotor, then caliper. (Refer to 5 -
BRAKES/HYDRAULIC/MECHANICAL/ROTOR -
INSTALLATION)
(11) Install wheel speed sensor head in steering
knuckle (Fig. 10). Install mounting bolt. Tighten
mounting bolt to 11 N·m (100 in. lbs.) torque.
(12) Verify proper wheel speed sensor-to-tone
wheel air gap. (Refer to 5 - BRAKES - ABS - SPEC-
IFICATIONS)
(13) Install outer tie rod onto steering knuckle.
Install a NEW tie rod nut. Tighten tie rod nut to 75
N·m (55 ft. lbs.) torque.
(14) Install tire and wheel assembly (Refer to 22 -
TIRES/WHEELS - INSTALLATION). Progressively
tighten wheel mounting nuts in proper sequence to
122 N·m (90 ft. lbs.) torque.
(15) Lower vehicle.
(16) Road test vehicle to ensure proper operation
of base brakes and ABS.
LOWER BALL JOINT
DESCRIPTION
The lower ball joint is pressed into the lower con-
trol arm. It has a tapered stud for attachment of the
ball joint to the steering knuckle (Fig. 14). The
tapered stud of the ball joint is fastened to the steer-
ing knuckle using a castle nut and a cotter pin.
Due to the lower control arm being made of alumi-
num and the ball joint being made of steel (dissimi-
lar metals), corrosion may occur between the pieces.
For this reason, the lower ball joint has a corrosion
preventative coating applied to it. A corrosion preven-
tion gasket is also used between the ball joint and
the lower control arm (Fig. 14).
DIAGNOSIS AND TESTING - LOWER BALL
JOINT (FRONT)
Replacement is necessary if more than 0.51 mm
(0.02 in.) axial end play of the ball joint stud exists.
Refer to the following procedure to inspect the lower
ball joint for wear.
CAUTION: When raising the vehicle by the lower
control arm using a floor jack, care must be used
so control arm does not get nicked, gouged,
deformed or damaged in any other way by the floor
jack.
(1) Position floor jack under outer end of front
lower control arm. Carefully raise vehicle so front
wheel and tire assembly is just lightly contacting
floor (vehicle weight relieved from tire).
(2) Have helper grasp tire at top and apply an
inward and outward force against top of the tire.
While force is being applied against tire, look for any
movement between lower ball joint and steering
knuckle.
(3) If any lateral movement is evident at lower ball
joint, replacement is necessary.

REMOVAL
NOTE: Review all Warnings and Cautions (Refer to
2 - SUSPENSION - WARNING)
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(2) Remove wheel and tire assembly. (Refer to 22 -
TIRES/WHEELS - REMOVAL)
(3) Remove brake caliper from knuckle and hang
out of the way, then remove brake rotor. (Refer to 5 -
BRAKES/HYDRAULIC/MECHANICAL/ROTOR -
REMOVAL)
(4) Remove bolt fastening wheel speed sensor head
to steering knuckle (Fig. 10). Remove sensor head
from knuckle.
(5) Loosen, but do not remove, nut attaching stabi-
lizer bar link to lower control arm (Fig. 17). Back off
and position nut at end of link stud (Fig. 18).
