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 -

LOWER CONTROL ARM
DESCRIPTION
The lower control arm is mounted to the front sus-
pension crossmember using a pivot bolt through the
center of the front pivot bushing, and the front sus-
pension cradle crossmember reinforcement traps the
rear bushing in the crossmember (Fig. 1).
The lower control arm is an iron casting with two
rubber bushings and a ball joint. The lower control
arm front bushing is the spool type and is pressed
into the lower control arm. The standard (Low-line)
lower control arm rear bushing is a push-on bushing
that is pushed over a stem on the rear of the lower
control arm. The optional (High-line, Premium,
Sport) lower control arm rear bushing is a hydro-
bushing that is pressed on. It has liquid filled voids
that provide more effective dampening than the stan-
dard bushing. Vehicles with rear hydro-bushings uti-
lize a different lower control arm than vehicles with
standard bushings. They have a straight slightly
tapered round stem where the hydro-bushing is
mounted whereas the standard arm has a straight
stem with a squared knob on the end to retain the
bushing.
The lower control arm ball joint is pressed into the
outer end of the arm. The ball joint has a tapered
stud and retainer nut for fastening it to the steering
knuckle.
OPERATION
The lower control arm supports the lower end of
the steering knuckle and allows for the up and down
movement of the suspension during the jounce and
rebound travel. The lower control arm ball joint con-
nects the arm to the steering knuckle.

OPERATION
The hub and bearing has internal bearings that
allow the hub to rotate with the tire and wheel
assembly (and driveshaft on All-Wheel-Drive vehi-
cles). The five wheel mounting studs mount the tire
and wheel assembly, and disc brake rotor or brake
drum to the vehicle.
On All-Wheel-Drive vehicles, the splined mating of
the driveshaft stub axle and hub allows the drive-
shaft to rotate with the hub and wheel.
Front-Wheel-Drive vehicles equipped with antilock
brakes have a wheel speed sensor and tone wheel
mounted to the rear of the hub and bearing. The tone
wheel rotates with the hub which is sensed by the
wheel speed sensor.
DIAGNOSIS AND TESTING - HUB AND
BEARING
The bearing contained in the hub and 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

BI-DIRECTIONAL
OVERRUNNING CLUTCH
DESCRIPTION
The bi-directional overrunning clutch (BOC) (Fig.
28) works as a mechanical disconnect between the
front and rear axles, preventing torque from being
transferred from the rear axle to the front. The BOC
is a simply an overrunning clutch which works in
both clockwise and counter-clockwise rotations. This
means that when the output (the rear axle) is rotat-
ing faster in one direction than the input (front axle),
there is no torque transmission. But when the input
speed is equal to the output speed, the unit becomes
locked. The BOC provides significant benefits regard-
ing braking stability, handling, and driveline durabil-
ity. Disconnecting the front and the rear driveline
during braking helps to maintain the braking stabil-
ity of an AWD vehicle. In an ABS/braking event, the
locking of the rear wheels must be avoided for stabil-
ity reasons. Therefore brake systems are designed to
lock the front wheels first. Any torque transfer from
the rear axle to the front axle disturbs the ABS/brak-
ing system and causes potential instabilities on aslippery surface. The BOC de-couples the rear driv-
eline as soon the rear wheels begin to spin faster
than the front wheels (front wheels locked) in order
to provide increased braking stability. Furthermore
the BOC also reduces the likelihood of throttle off
over-steer during cornering. In a throttle off maneu-
ver, the BOC once again de-couples the rear driveline
forcing all the engine brake torque to the front
wheels. This eliminates the chance of lateral slip on
the rear axle and increases it on the front. The vehi-
cle will therefore tend to understeer, a situation
which is considered easier to manage in most circum-
stances. During this maneuver, and during the ABS
braking event, the BOC does not transmit torque
through to the rear wheels. The rear driveline mod-
ule, with the BOC, will perform the same as a front
wheel drive vehicle during these events. The gear
ratio offset between the front and rear differentials
force the BOC into the overrunning mode most of the
time. This allows BOC to significantly reduce the
rolling resistance of the vehicle, which improves fuel
consumption, allows the downsizing of the driveline
components, and prevents the PTU and propshaft
joints from overheating.
