INSTALL
CAUTION: Hub and bearing assembly mounting
surfaces on the steering knuckle and halfshaft (Fig.
60) must be smooth and completely free of foreign
material or nicks prior to installing hub and bearing
assembly.
CAUTION: When installing hub and bearing
assembly into steering knuckle, be careful not to
damage the bearing seal (Fig. 60) on the outer C/V
joint.
(1) Install hub/bearing assembly onto stub axle
and into steering knuckle until squarely seated on
the face of the steering knuckle.
(2) Install the 4 hub/bearing assembly to steering
knuckle attaching bolts (Fig. 58). Equally tighten all
4 mounting bolts in a criss-cross pattern until hub/
bearing assembly is squarely seated against front ofsteering knuckle. Then tighten the 4 hub and bearing
assembly mounting bolts to a torque of 65 N´m (45
ft.lbs.)
(3) Install the hub/bearing assembly to stub shaft
washer and retaining nut (Fig. 61).Tighten, but do
not torque the hub nut at this time.
(4) Install the braking disk on the hub and bearing
assembly.
(5) Install front brake caliper back over braking
disc and align with caliper mounting holes on steer-
ing knuckle (Fig. 55). Caliper is installed by first
installing bottom of caliper under machined abut-
ment on bottom of steering knuckle and then rotat-
ing top of caliper toward steering knuckle. Install the
disc brake caliper to steering knuckle attaching bolts
(Fig. 54) and tighten to a torque of 19 N´m (168 in.
lbs.).
(6) Install wheel and tire assembly on vehicle.

sequence until all nuts are torqued to half specifica-
tion. Then repeat the tightening sequence to the full
specified torque of 129 N´m (95 ft. lbs.).
(7) Lower vehicle to the ground.
CAUTION: When tightening hub/bearing assembly
to stub shaft retaining nut, do not exceed the max-
imum torque of 244 N´m (180 ft. lbs.).
(8) With vehicle brakes applied to keep vehicle
from moving, torque stub shaft to hub/bearing assem-
bly retaining nut to 244 N´m (180 ft. lbs.).
(9) Check the Toe setting on the vehicle and reset
if not within specifications.
FRONT WHEEL MOUNTING STUDS
REMOVE
CAUTION: If a wheel attaching stud needs to be
replaced in the hub and bearing assembly the studs
CAN NOT be hammered out of the hub flange. If a
stud is removed by hammering it out of the bearing
flange, damage to the hub and bearing assembly
will occur leading to premature bearing failure.
The following procedure and special tools shown
MUST BEused when replacing wheel attaching
studs.
The hub and bearing assembly does not require
removal from the steering knuckle to replace wheel
attaching studs in the hub and bearing assembly.
(1) Raise vehicle on jackstands or centered on a
frame contact type hoist. See Hoisting in the Lubri-
cation and Maintenance section of this manual for
the required lifting procedure to be used for this
vehicle.
(2) Remove the front wheel and tire assembly from
the vehicle.
(3) Remove the front caliper assembly from the
front steering knuckle assembly. (Fig. 62) Refer to
Front Disc Brake Service in the Brake Section of this
service manual for caliper removal procedure.
(4) Remove front rotor from hub, by pulling it
straight off wheel mounting studs. (Fig. 63)
(5) Install a lug nut on the wheel stud to be
removed from the hub and bearing assembly, so the
threads on the stud are even with end of lug nut.
Install Remover, Special Tool C-4150A on hub and
bearing assembly flange and wheel stud (Fig. 64).
(6) Tightening down on special tool will push
wheel stud out of the hub and bearing assembly
flange. When shoulder of wheel stud is past flange
remove special tool from hub and bearing assembly.
Remove lug nut from stud and remove wheel stud
from flange.
INSTALL
(1) Install replacement wheel stud into flange of
hub and bearing assembly. Install washers on wheel
stud, then install a wheel lug nut on stud with flat
side of lug nut against washers (Fig. 65).
(2) Tighten the wheel lug nut, pulling the wheel
stud into the flange of the hub and bearing assembly.
When the head of the stud is fully seated against the
bearing flange, remove lug nut and washers from
wheel stud.
(3) Install the braking disk back on the hub and
bearing assembly. (Fig. 63)

(4) Install front brake caliper back over braking
disc and align with caliper mounting holes on steer-
ing knuckle (Fig. 62). Refer to Front Disc Brake Ser-
vice in the Brake Section of this service manual for
caliper installation procedure. Install the caliper
adapter to steering knuckle attaching bolts and
torque to 19 N´m (168 in. lbs.).
(5) Install wheel and tire assembly on vehicle.
Tighten the wheel mounting stud nuts in proper
sequence until all nuts are torqued to half specifica-
tion. Then repeat the tightening sequence to the full
specified torque of 129 N´m (95 ft. lbs.).

REAR WHEEL MOUNTING STUDS
REMOVE
CAUTION: If a wheel attaching stud needs to be
replaced in the hub and bearing assembly the studs
CAN NOT be hammered out of the hub flange. If astud is removed by hammering it out of the bearing
flange, damage to the hub and bearing assembly
will occur leading to premature hub and bearing
failure.
The following procedure and special tools shown
MUSTbe used when replacing wheel attaching
studs.
The hub and bearing assembly does not require
removal from the rear axle for replacement of the
wheel attaching studs.
(1) Raise vehicle on jackstands or centered on a
frame contact type hoist. See Hoisting in the Lubri-
cation and Maintenance section of this manual, for
the required lifting procedure to be used for this
vehicle.
(2) Remove the rear wheel and tire assembly.
(3) Remove the rear brake drum.
(4) Install a lug nut on the wheel stud to be
removed from the hub and bearing assembly (Fig. 66)
so the threads on stud are even with end of lug nut.
Install Remover, Special Tool C-4150A on hub and
bearing assembly flange and wheel stud (Fig. 66).
(5) Tightening down on special tool will push
wheel stud out of the hub and bearing assembly
flange. Remove lug nut from stud and remove wheel
stud from flange.
INSTALL
(1) Install replacement wheel stud into flange of
hub and bearing assembly. Install washers on wheel
stud, then install a wheel lug nut on stud with flat

GENERAL INFORMATION
REAR SUSPENSION
The rear suspension design on this vehicle uses
leaf springs and a tube and casting axle (Fig. 1) and
(Fig. 2). It is designed to handle the various load
requirements of the vehicle. The leaf springs used on
the rear suspension of this vehicle are of either a
mono-leaf or multi-leaf design.The rear axle used on front wheel drive applica-
tions of this vehicle is mounted to the rear leaf
springs using isolator bushings at the axle mounting
brackets.
The rear axle used on all wheel drive applications
of this vehicle is also mounted to the rear leaf
springs but does not use isolator bushings between
the rear axle and the leaf springs.
