HUB / BEARING
DESCRIPTION
The front wheel bearing and front wheel hub of
this vehicle are a hub and bearing unit type assem-
bly (Unit III). This unit combines the front wheel
mounting hub (flange) and the front wheel bearing
into a sealed one-piece unit. The hub and bearing is
mounted to the center of the steering knuckle (Fig.
1). It is retained by four mounting bolts accessible
from the inboard side of the steering knuckle. The
hub flange has five wheel mounting studs.
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. Other-
wise, the hub and bearing is serviced only as a com-
plete assembly.
OPERATION
The hub and bearing has internal bearings that
allow the hub to rotate with the driveshaft, along
with the tire and wheel. The five wheel mounting
studs mount the tire and wheel, and brake rotor to
the vehicle.

DIAGNOSIS AND TESTING - HUB AND
BEARING
The condition of the front hub and bearing assem-
bly is diagnosed using the inspection and testing pro-
cedure detailed below.
The bearing contained in the Unit III front hub/
bearing assembly will produce noise and vibration
when worn or damaged. The noise will generally
change when the bearings are loaded. A road test of
the vehicle is normally required to determine the
location of a worn or damaged bearing.
Find a smooth level road surface and bring the
vehicle up to a constant speed. When vehicle is at a
constant speed, swerve the vehicle back and forth
from the left and to the right. This will load and
unload the bearings and change the noise level.
When bearing damage is slight, the noise is some-
times noticeable at lower speeds and at other times
is more noticeable at speeds above 105 km/h (65
mph).
REMOVAL
NOTE: Replacement of the Unit III front hub/bearing
assembly can be normally done without having to
remove the steering knuckle from the vehicle. In the
event that the hub/bearing is frozen in the steering
knuckle and cannot be removed by hand, it will
have to be pressed out of the steering knuckle. The
steering knuckle will require removal from the vehi-
cle to allow the hub/bearing assembly to be
pressed out of the steering knuckle. (Refer to 2 -
SUSPENSION/FRONT/KNUCKLE - REMOVAL)
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(2) Remove wheel lug nuts, and front tire and
wheel assembly.
(3) Remove the cotter pin, nut lock and spring
washer from the stub axle (Fig. 4).
(4) With aid of a helper applying the brakes to
keep the front hub from turning, remove the hub nut
(Fig. 4).
(5) Remove disc brake caliper and adapter as an
assembly from knuckle as shown (Fig. 5). Hang
assembly out of the way using a bungee cord or wire.
Do not allow caliper hang by brake hose.
(6) Remove brake rotor from hub and bearing (Fig.
5).
(7) Push in on end of driveshaft stub shaft, push-
ing its splines out of the hub splines.(8) Remove the four hub and bearing mounting
bolts from the rear of steering knuckle (Fig. 6).Use
care not to come in contact with and damage
the ABS tone wheel on the driveshaft stub shaft
upon bolt removal.
(9) Remove the hub and bearing assembly from
the steering knuckle.

KNUCKLE
DESCRIPTION
The steering knuckle is a singlealuminumcast-
ing with legs machined for attachment of the strut
assembly, steering linkage, disc brake caliper
adapter, lower control arm ball joint and steering
linkage (Fig. 1). The hub and bearing assembly is
mounted in the center of the steering knuckle using
4 bolts. The driveshaft's constant velocity (C/V) stub
axle is splined through the center of the hub and
bearing and is held in place using a nut, nut lock and
cotter pin.
Service replacement of the front hub and bearing
assembly can be done with the steering knuckle
remaining on the vehicle.
OPERATION
The steering knuckle pivots with the strut assem-
bly between the lower ball joint and the pivot bearing
in the strut assembly. The steering gear outer tie rod
end connects to the trailing end of each knuckle,
allowing the vehicle to be steered.
