HUB / BEARING
DESCRIPTION
The bearing used on the front hub of this vehicle is
the combined hub and bearing unit type assembly.
This unit combines the front wheel mounting hub
(flange) and the front wheel bearing into a one piece
unit. The hub and bearing assembly is mounted to
the steering knuckle and is retained by three mount-
ing bolts accessible from the back of the steering
knuckle. The hub and bearing unit is not serviceable
and must be replaced as an assembly if the bearing
or the hub is determined to be defective. The wheel
mounting studs used to mount the tire and wheel to
the vehicle are the only replaceable components of
the hub and bearing assembly.
OPERATION
The hub and bearing has internal bearings that
allow the hub to rotate with the driveshaft and tire
and wheel.
DIAGNOSIS AND TESTING - HUB AND
BEARING
The hub and bearing is designed for the life of the
vehicle and requires no type of periodic maintenance.
The following procedure may be used for diagnosing
the condition of the wheel bearing and hub.
With the wheel, disc brake caliper, and brake rotor
removed, rotate the wheel hub. Any roughness or
resistance to rotation may indicate dirt intrusion or a
failed hub bearing. If the bearing exhibits any of
these conditions during diagnosis, the hub bearing
will require replacement. The bearing is not service-
able.
Damaged bearing seals and the resulting excessive
grease loss may also require bearing replacement.
Moderate grease weapage from the bearing is consid-
ered normal and should not require replacement of
the wheel bearing.
To diagnose a bent hub, (Refer to 2 - BRAKES/HY-
DRAULIC-MECHANICAL/ROTOR
-
DIAGNOSIS
AND TESTING).
REMOVAL
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/JUMP STARTING - STANDARD
PROCEDURE).
(2) Remove front tire and wheel assembly.
CAUTION: Wheel bearing damage will result if hub
nut is loose, then vehicle is rolled on the ground or
the weight of the vehicle is allowed to be supported
by the tires.
(3) Loosen hub nut with brakes applied. The hub
and driveshaft are splined together through the
knuckle (bearing) and retained by the hub nut.
(4) Remove disc brake caliper, adapter, shoes and
rotor from steering knuckle. (Refer to 5 - BRAKES/
HYDRAULIC/MECHANICAL/ROTOR - REMOVAL)
(5) If equipped with antilock brakes, remove bolt
securing wheel speed sensor cable routing bracket to
steering knuckle (Fig. 3).
(6) Remove nut from upper ball joint stud.
(7) Remove upper ball joint stud from steering
knuckle using Puller, Special Tool, C-3894-A (Fig. 4).

NOTE: Care must be taken not to separate drive-
shaft inner C/V joint during the following steps. Do
not allow driveshaft to hang by inner C/V joint;
driveshaft must be supported.
(8) Separate steering knuckle (hub and bearing)
from outer C/V joint by tipping top of steering
knuckle outward while sliding outer C/V joint out
rear of hub and bearing. Once separated, support
outer end of driveshaft with wire hanger or cord to
avoid damaging inner C/V joint.
(9) Remove 3 bolts attaching the hub and bearing
assembly to steering knuckle (Fig. 5).
(10) Remove hub and bearing assembly from front
of steering knuckle.
NOTE: If bearing will not come out of steering
knuckle, it can be tapped out using a soft faced
hammer.
INSTALLATION
(1) Thoroughly clean all hub and bearing assembly
mounting surfaces on steering knuckle.
(2) Install hub and bearing assembly in steering
knuckle aligning bolt holes in bearing flange with
holes in steering knuckle.
(3) Install 3 mounting bolts (Fig. 5) and tighten
evenly to ensure bearing is square to face of steering
knuckle. Tighten mounting bolts to 110 N·m (80 ft.
lbs.) torque.
(4) Slide driveshaft outer C/V into front hub and
bearing assembly.
(5) Install steering knuckle onto upper ball joint
stud and install nut.
(6) Using a crow foot and torque wrench, tighten
upper ball joint nut to 27 N·m (20 ft. lbs.) torque.
(7) If equipped with antilock brakes, install wheel
speed sensor cable routing bracket on steering
knuckle (Fig. 3). Install and tighten mounting bolt to
12 N·m (105 in. lbs.) torque.
(8) Install brake rotor, and caliper, shoes and
adapter assembly. (Refer to 5 - BRAKES/HYDRAU-
LIC/MECHANICAL/ROTOR - INSTALLATION)
(9) Clean all foreign matter from threads of outer
C/V joint stub axle.
(10) Install hub nut on C/V joint stub axle threads.
With vehicle brakes applied to keep stub axle from
turning, tighten hub nut to 203 N·m (150 ft. lbs.)
torque.
(11) Install wheel and tire assembly. Install wheel
mounting nuts and progressively tighten in crisscross
sequence. Tighten nuts to a torque of 135 N·m (100
ft. lbs.).
(12) Lower vehicle.
(13) Set front toe on vehicle to required specifica-
tion. (Refer to 2 - SUSPENSION/WHEEL ALIGN-
MENT - STANDARD PROCEDURE).
KNUCKLE
DESCRIPTION
The steering knuckle is a single casting with legs
machined for attachment to the vehicle’s upper and
lower control arm ball joints. the steering knuckle
has the hub and bearing mounted in its center. The
axle shaft constant velocity joint stub shaft is splined
through the hub and bearing assembly in the center
of the knuckle. The steering knuckle also supports
and aligns the front brake caliper adapter and cali-
per assembly.
OPERATION
The steering knuckle pivots between the upper and
lower ball joints. The steering gear outer tie rod end
connects to the trailing end of each knuckle, allowing
the vehicle to be steered.
The center of the knuckle supports the hub and
bearing and axle shaft.
DIAGNOSIS AND TESTING - STEERING
KNUCKLE
The front suspension steering knuckle is not a
repairable component of the front suspension. It
must be replaced if found to be damaged in any way.
If it is determined that the steering knuckle is bent
when servicing the vehicle, no attempt is to be made
to straighten the steering knuckle.

REMOVAL
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - SERVICE PROCE-
DURE).
(2) Remove front tire and wheel assembly from
hub.
CAUTION: Wheel bearing damage will result if hub
nut is loosened, then vehicle is rolled on the
ground or the weight of the vehicle is allowed to be
supported by the tires.
(3) Loosen hub nut with brakes applied.The hub
and driveshaft are splined together through the
knuckle (bearing) and retained by the hub nut.
(4) Remove disc brake caliper, adapter, shoes and
rotor from steering knuckle. (Refer to 5 - BRAKES/
HYDRAULIC/MECHANICAL/ROTORS - REMOVAL)
(5) Remove nut attaching outer tie rod to steering
knuckle (Fig. 6). Remove nut from tie rod by
holding tie rod stud with a socket while loosen-
ing and removing nut with wrench (Fig. 6).
(6) Remove the tie rod end from the steering
knuckle using Remover, Special Tool C-3894-A.
(7) Remove ABS wheel speed sensor cable routing
bracket from steering knuckle (Fig. 7).
(8) Remove cotter pin and castle nut from lower
ball joint stud (Fig. 8).
CAUTION: No tool is to be inserted between the
steering knuckle and the lower ball joint to separate
stud of lower ball joint from the steering knuckle.
The steering knuckle is to be separated from the
stud of the ball joint only using the procedure as
described in Step 9 below.
