HUB / BEARING

DESCRIPTION

The rear wheel bearing and rear wheel hub of this

vehicle are a one piece sealed unit or hub and bear-
ing unit type assembly. The hub and bearing is
mounted to the center of the spindle using a retain-
ing nut (Fig. 1). It has five wheel mounting studs on
the hub flange.

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.

CAUTION: If a vehicle is equipped with antilock
brakes, the tone wheel for the rear wheel speed
sensor is pressed onto the hub and bearing.

OPERATION

The hub and bearing has internal bearings that

allow the hub to rotate with the tire and wheel. The
five wheel mounting studs mount the tire and wheel,
and disc brake rotor to the vehicle.

DIAGNOSIS AND TESTING - HUB AND
BEARING (REAR)

The rear hub and bearing assembly is designed for

the life of the vehicle and should require no mainte-
nance. The following procedure may be used for eval-
uation of bearing condition.

With wheel and brake drum removed, rotate

flanged outer ring of hub. Excessive roughness, lat-
eral play or resistance to rotation may indicate dirt
intrusion or bearing failure. If the rear wheel bear-
ings exhibit these conditions during inspection, the
hub and bearing assembly should be replaced.

Damaged bearing seals and resulting excessive

grease loss may also require bearing replacement.
Moderate grease loss from bearing is considered nor-
mal and should not require replacement of the hub
and bearing assembly.

REMOVAL - HUB AND BEARING (REAR)

(1) Raise vehicle on jackstands or centered on a

frame contact hoist. See Hoisting in Lubrication and
Maintenance.

(2) Remove the rear wheel and tire assembly from

the vehicle.

(3) Remove the rear caliper assembly from the

adapter. Refer to Disc Brake Caliper in Brakes. After
removing caliper assembly, store caliper by hanging
it from frame of vehicle (Fig. 2). Do not let weight of
rear caliper assembly hang from flexible brake hose.

(4) Remove rear brake rotor from hub.

bearing retaining nut and washer from the spindle
(Fig. 3). Remove hub and bearing assembly from
spindle.

INSTALLATION - HUB AND BEARING (REAR)

(1)

Install the rear hub and bearing assembly on

the rear spindle. Install hub and bearing assembly
retaining washer and nut on spindle (Fig. 3). Tighten
the hub and bearing retaining nut to a torque of 168
N·m (124 ft. lbs.). Install the nut retainer and cotter
pin.

(2) Install the rear brake rotor on the hub.
(3) Carefully place rear brake caliper over rotor

and install on adapter. Refer to Disc Brake Caliper in
Brakes.

(4) 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 135 N·m (100 ft. lbs.).

(5) Lower vehicle to the ground.

LATERAL LINK

DESCRIPTION

There are two tubular lateral links on each side of

the rear suspension (Fig. 1). The lateral links have
rubber isolator bushings at each end. They are
attached to the rear suspension crossmember, and
the spindle using a bolt and nut assembly at each
end. The rear lateral link incorporates a threaded
wheel alignment toe adjustment sleeve.

OPERATION

The lateral movement of the rear spindle is con-

trolled by the lateral links connecting the front and
rear centerline of the spindle to the rear suspension
crossmember. The threaded adjustment sleeve of the
rear link allows for setting rear wheel alignment toe
adjustment.

DIAGNOSIS AND TESTING - LATERAL LINKS

Inspect the lateral link isolator bushings and

sleeves for signs of damage or deterioration. If the
lateral link isolator bushings or sleeves are damaged
or are deteriorated, replacement of the lateral link
assembly will be required. The isolator bushings are
not serviceable as a separate component of the lat-
eral link assembly.

Inspect the lateral links for signs of contact with

the ground or road debris which has bent or caused
other damage to the lateral link assembly. If the lat-
eral link is bent or damaged, the lateral link will
require replacement. Do not attempt to repair or
straighten a lateral link.

REMOVAL - LATERAL LINKS

The left forward lateral link requires a more

involved removal and installation procedure in order
to remove the attaching bolt at the crossmember. See
separate procedures below for the proper lateral link
service procedure.

LEFT FORWARD LATERAL LINK

(1) Raise vehicle on jackstands or centered on a

frame contact hoist. See Hoisting in Lubrication and
Maintenance.

(2) Remove left rear wheel and tire assembly from

the vehicle.

(3) Remove the nut and bolt attaching the left lat-

eral links to the spindle (Fig. 4).

(4) Remove the nut attaching the left forward lat-

eral link to the rear suspension crossmember. The
bolt for the left front lateral link may not be
removed at this time. Remove the nut only.
Once the crossmember is lowered, the bolt can
be easily removed. Notice the forward link attach-
ing bolt faces rearward.

CAUTION: The bolts attaching the forward lateral
links to the crossmember must be installed with the
bolts pointing rearward (Fig. 5)to prevent damage to
the fuel tank and or fuel tubes. Also, the left rear
lateral arm attaching bolt to the crossmember is to
be installed pointing forward to prevent possible
damage to the fuel filler tube.

(5) Remove the screw securing the brake tubes to

the left stabilizer bar isolator bushing retainer.

(6)

Remove the 4 bolts attaching both stabilizer

bar isolator bushing retainers to the frame rails (the
2 rearward attaching bolts also attach the front cor-
ners of the rear suspension crossmember in place).
Allow the stabilizer bar to hang down out of the way.

(7) Remove the screw securing the fuel filler neck

to the left frame rail.

(8) Position a transmission jack under the fuel

tank.

(9) Remove the attaching bolts securing both fuel

tank mounting straps. First, remove the right , then
the left attaching bolt. Allow the straps to hang
down.

(10) Lower the transmission jack and fuel tank
