be necessary to place a wooden block between the
spring and vehicle to hold forward end of the spring
in place.
(6) Remove leaf spring forward pivot bolt, then
remove mounting bracket.
INSTALLATION
(1) Position spring mounting bracket over spring
eye and install pivot bolt through center of bushing
from theoutboardside.
NOTE: The pivot bolt must be installed from the
outboard side to allow proper bracket to body
mounting.
(2) Install the nut on the pivot bolt and lightly
tighten. Do not fully tighten bolt at this time.
(3) Raise the under-hoist utility jack or transmis-
sion jack, guiding the forward mounting bracket into
place against the body. It may help to use a drift
punch placed through the hole centered between the
mounting bolt holes in the bracket and the pilot hole
in the body of the vehicle as a guide. When the four
mounting bolt holes line up with their threads in the
body, Install the mounting bolts (Fig. 37). Tighten the
four mounting bolts to 61 N´m (45 ft. lbs.) torque.
(4) Raise or lower the jack until shock absorber
lower eye aligns with threads in axle housing. Install
shock absorber lower mounting bolt. Do not fully
tighten bolt at this time.
(5) Lower the vehicle and remove hoist arms and
block of wood from under vehicle.
(6) Tighten the spring front pivot bolt to 156 N´m
(115 ft. lbs.) torque.
(7) Tighten the lower shock absorber mounting
bolt to 88 N´m (65 ft. lbs.) torque.
SPRING MOUNTS - REAR
REMOVAL
(1) Remove the attaching nuts and bolts from the
leaf spring rear shackle (Fig. 38) and (Fig. 39).
(2) Install a jackstand under the side of the axle
having the leaf spring mount removed. Using the
jackstand, support the weight of the axle and leaf
spring.(3) Remove the lower mounting bolt from the
shock absorber.
(4) Remove the bolts attaching the leaf spring rear
mount to the body of the vehicle (Fig. 40).
(5) Lower the jackstand and the rear of the leaf
spring. Remove the shackle from the leaf spring
bushing.

HALF SHAFT - FRONT
DESCRIPTION
All vehicles use an unequal length half shaft sys-
tem (Fig. 1).
The left half shaft uses a tuned rubber damper
weight. When replacing the left half shaft, be sure
the replacement half shaft has the same damper
weight as the original.
All half shaft assemblies use the same type of
inner and outer joints. The inner joint of both half
shaft assemblies is a tripod joint, and the outer joint
of both half shaft assemblies is a Rzeppa joint. Both
tripod joints and Rzeppa joints are true constant
velocity (CV) joint assemblies. The inner tripod joint
allows for the changes in half shaft length through
the jounce and rebound travel of the front suspen-
sion.
On vehicles equipped with ABS brakes, the outer
CV joint is equipped with a tone wheel used to deter-
mine vehicle speed for ABS brake operation.
The inner tripod joint of both half shafts is splined
into the transaxle side gears. The inner tripod joints
are retained in the side gears of the transaxle using
a snap ring located in the stub shaft of the tripod
joint. The outer CV joint has a stub shaft that is
splined into the wheel hub and retained by a steel
hub nut.
DIAGNOSIS AND TESTING - HALF SHAFT
VEHICLE INSPECTION
(1) Check for grease in the vicinity of the inboard
tripod joint and outboard CV joint; this is a sign of
inner or outer joint seal boot or seal boot clamp dam-
age.
NOISE AND/OR VIBRATION IN TURNS
A clicking noise and/or a vibration in turns could
be caused by one of the following conditions:
²Damaged outer CV or inner tripod joint seal
boot or seal boot clamps. This will result in the loss
and/or contamination of the joint grease, resulting in
inadequate lubrication of the joint.
²Noise may also be caused by another component
of the vehicle coming in contact with the half shafts.
CLUNKING NOISE DURING ACCELERATION
This noise may be a result of one of the following
conditions:
²A torn seal boot on the inner or outer joint of the
half shaft assembly.
²A loose or missing clamp on the inner or outer
joint of the half shaft assembly.
²A damaged or worn half shaft CV joint.

If seal boot uses low profile latching type boot
clamp, use the following procedure to install the
retaining clamp.
(1) Place prongs of clamp locking tool in the holes
of the clamp (Fig. 25).
(2) Squeeze tool together until top band of clamp is
latched behind the two tabs on lower band of clamp
(Fig. 26).
(14) Install the half shaft back into the vehicle.

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 a
slippery 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

This lock-up is not desired, and requires the use of
another mechanism to prevent the lock-up. The
device that prevents undesired high-speed lock-up is
called a9high speed latch9.
Similar to the friction shoes, the two-piece high-
speed latch will separate from each other at high
rotational speeds due to centrifugal effects. (Fig. 35)
shows the high speed latch engaged. The gap9x9
increases with speed, eventually locking into one of
the slots in the BOC shaft. When the high-speed
latch is activated (propeller shaft speed reaches X
amount), the cage is partially fixed, and cannot lock
on the wrong side of the flat as shown (Fig. 34). The
high speed latch is a one way device and does not
prevent high-speed lockup in the reverse direction. At
high speeds, the BOC provides the same function as
low speeds, transferring torque to the viscous coupler
only when front wheel slip overcomes the axle ratio
offset.
At high speed, the rollers are forced outward to the
outer race because of centrifugal force. At high
speeds, the friction shoes can no longer prevent lock-
up. When the teeth on the high-speed latch engage
into the input shaft, it keeps the rollers centered
above the flats because the tabs on the latch are
locked into the cage. (Fig. 36) shows the roller config-
uration with the High-Speed Latch engaged.
On the BOC shaft, the high speed latch teeth lock
up in the grooved areas, shown in (Fig. 37), when the
turning speed reaches the critical value. (Fig. 37)
