metal-to-metal contact of the rear axle with the
frame under full jounce conditions.
REMOVAL - AWD AND HEAVY DUTY
(1) Using slip-joint pliers grasp the base of the
jounce bumper. Turn the base counterclockwise (Fig.
21).
(2) Remove the jounce bumper from the frame rail.
REMOVAL - FRONT-WHEEL-DRIVE

SPRING - AWD
DESCRIPTION
The leaf springs used on the rear suspension of
this vehicle are of either a mono-leaf or multi-leaf
design depending on model and options.
Since the rear springs come in various designs and
rates, be sure the correct spring is in use.
OPERATION
The leaf spring controls ride quality and maintains
ride height.
REMOVAL - AWD
(1) Raise vehicle on frame-contact hoist as follows:
(a) Position the hoist arm supporting the corner
of the vehicle to be serviced against a block of wood
placed on the body sill as shown (Fig. 27).
(b) Position the remaining hoist arms at each
corner of the vehicle in the normal fashion. (Refer
to LUBRICATION & MAINTENANCE/HOISTING
- STANDARD PROCEDURE)
(c) Raise the vehicle to a comfortable working
level.
(2) Position an under-hoist utility jack or transmis-
sion jack under rear axle toward the side needing
spring replacement. Jack pad should just contact
axle.NOTE: If shock absorber bolt deflects upward dur-
ing removal, raise axle by adjusting support jack. If
shock absorber bolt deflects downward during
removal, lower axle by adjusting support jack (or by
pulling on axle).
(3) Begin removal of the shock absorber lower
mounting bolt (Fig. 28).

CAUTION: After slotting the strut clevis bracket
hole, do not install the original attaching bolts when
assembling the steering knuckle to the strut assem-
bly. Only the flange bolts, cam bolts, and dog bone
washers from the service package must be used to
attach the steering knuckle to the strut after the
mounting hole is slotted.
(5) Position the knuckle back into the strut clevis
bracket. Install a flanged bolt from the service pack-
age into the upper mounting hole. Install a cam bolt
into the bottom mounting hole. Both bolts should
point forward once installed (Fig. 9).
(6) Install a dog bone washer on the steering
knuckle to strut clevis bracket attaching bolts, then
install the nuts onto the bolts from the service pack-
age (Fig. 10). Tighten the bolts just enough to hold
the steering knuckle in position when adjusting cam-
ber, while still allowing the steering knuckle to move
in clevis bracket.
(7) Repeat the procedure to the other side strut
clevis bracket.
(8) Reinstall both front tire and wheel assemblies
and tighten to specifications.
(9) Lower the vehicle. Jounce the front and rear of
vehicle an equal amount of times.
(10) Adjust the front camber to the preferred set-
ting by rotating the lower eccentric cam bolt against
the cam stop areas on the strut clevis bracket (Fig.
11). When camber is set, tighten the upper strut cle-
vis bracket bolt and lower cam bolt. Again jounce
front and rear of vehicle an equal amount of times
and verify front camber setting. Torque both frontstrut to steering knuckle attaching bolts to 81 N´m
(60 ft. lbs.) plus an additional 1/4 (90É) turn after the
required torque is met.
(11) If toe readings obtained are not within the
required specification range, adjust toe to meet the
preferred specification setting. Toe is adjustable
using the following procedure.
