INSPECTION/LUBRICATION SCHEDULE

2WD
VEHICLES
It is recommended that 2WD front wheel bearings
be inspected for proper lubrication whenever the
brake rotors are removed or at least: • At each 39 000 km (24,000 miles) interval for ve­
hicles subject to the LIGHT DUTY CYCLE Mainte­ nance Schedule • At each 36 000 km (22,500 miles) interval for ve­
hicles subject to the HEAVY DUTY CYCLE Mainte­ nance Schedule The bearings should be cleaned and re-packed
with a high temperature, multi-purpose EP lu­
bricant.
4WD
VEHICLES

It is recommended that 4WD front wheel bearings
be inspected for proper lubrication whenever the
brake rotors are removed or at least:
• At each 24 000 km (15,000 miles) interval for ve­
hicles subject to the LIGHT DUTY CYCLE Mainte­ nance Schedule
• At each 19 000 km (12,000 miles) interval for ve­
hicles subject to the HEAVY DUTY CYCLE Mainte­ nance Schedule
For vehicles used for extensive off-road, 4WD
operation, the front wheel bearings should be in­ spected every 1 600 km (1,000 miles).
The bearings should be cleaned and re-packed
with a high temperature, multi-purpose EP lu­
bricant whenever the disc brake rotors are re­ surfaced.
INSPECTION If the lubricant:
• Is not sufficient
• Contaminated with foreign particles
• Appears dry or has been contaminated with water
to produce a milky appearance, the bearings should
be cleaned and re-packed with lubricant.

CAUTION:
Do not add
lubricant
to the
wheel
bear­
ings.
Re-pack completely. Mixing
of
different
types
of lubricants
in
wheel
bearings should
be
avoided.
This could possibly result
in
excessive thinning
and
leakage
of the
lubricant.

LUBRICATION (1) Discard the original seal.
(2) Clean the original lubricant from the bearings
and from the hub cavity (Figs. 2 and 3).
(3) Inspect the bearing rollers for indications of
pitting. Light bearing roller discoloration is consid­ ered normal. A wheel bearing must be replaced if any serious damage exists.
(4) Re-pack the bearings with a high temperature,
multi-purpose NLGI GC-LB lubricant. The use of a
bearing packer is recommended. A small amount of fresh lubricant also should be added to the hub cav­ ity.
BEARING INSTALLA TION/ADJUSTMENT (1) Install the hub/rotor (with inner bearing and
seal) on steering knuckle spindle.
(2) Install the outer bearing, the thrust washer
and the nut.
(3) Tighten wheel bearing nut to 27-34 N^m (240-
300 in. lbs.) torque while rotating hub/rotor. This
will seat the bearings.
(4) Loosen the nut 1/4 of-a-turn (90°), then tighten
it finger-tight.

ings.
These bearings are lubricated by the axle hous­
ing sump.

LOWER
AND UPPER
SUSPENSION
ARM

BUSHINGS

INSPECTION
SCHEDULE
The lower and upper suspension arm bushings
should be inspected each time the underside of the
vehicle is serviced.

INSPECTION
The lower suspension arm bushings can be visually
inspected by raising the vehicle on a hoist and in­ specting from underneath. The upper suspension arm
bushings can be inspected after removing the front wheels. If failure exists, replace the bushing (refer to Group 2—Front Suspension for the proper proce­

dures).

The suspension arm bushings never should be
lubricated.

GUIDELINES
(1) Faulty bushings are detected by the bushing
being off-center in relation to the outer sleeve.
(2) Total failure is evident by excessive movement
within the bushing.

(3)
Small cracks in the outer, non-confined rubber
does not indicate failure of the rubber. '

POWER BRAKE SYSTEM
Vehicles are equipped with power disc brakes at
the front wheels and drum brakes at the rear wheels.

MASTER CYLINDER

FLUID
LEVEL INSPECTION
The brake fluid level should be inspected at the
same time as other underhood service is done (Fig.

4).
If necessary, add fluid to raise the level to the
bottom of the split rings. With disc-brakes, the fluid level can be expected to lower as the brake pads
wear. However, a low fluid level can also be caused
by a leak, and repair will then be necessary.

runout and unbalance. Refer to Group 22, Wheels and Tires for diagnosis information.
(5) Suspension components for wear and noise. Check
components for correct torque. Refer to Groups 2 and 3, Suspension and Axle for additional information.

WHEEL
ALIGNMENT
MEASUREMENTS/ADJUSTMENTS
The front wheel alignment positions must be set to
the specified limits. This will prevent abnormal tire
tread wear. The equipment manufacturer's recommenda­
tions for use of their
equipment
should always
be followed. All
damaged
front suspension sys­
tem components
should
be replaced. Do not at­ tempt to straighten any
bent
component.

CAMBER AND CASTER-2WD VEHICLES Camber and caster angle adjustments involve repo­
sitioning the upper suspension arm cam adjustment
bolts (Fig. 2). Alignment adjustments are accom­
plished by loosening the nuts and changing the posi­
tion of the cam bolt.
(1) Remove all foreign material from the adjust­
ment bolt threads.
(2) Record the camber and caster measurements
before loosening the adjustment bolt nuts.
(3) The camber angle should be adjusted as near as
possible to the preferred angle. The caster should be
the same at both sides of the vehicle. Refer to the Specifications chart.
CAMBER AND CASTER—4WD VEHICLES For 4WD vehicles, the correct wheel camber (verti­
cal tilt) angle is factory preset at zero degree (0°).
Camber cannot be altered by adjustment.
CAUTION: Do not attempt to
adjust
the
camber
an­
gle by
heating
or bending the axle or any
suspen­

sion
component. If camber angle is
incorrect,
the
component(s)
causing
an
incorrect
angle must be replaced.
(1) It is important that the camber (vertical tilt)
angle be the same for both front wheels.
(2) The camber angle should be measured with ac­
curate wheel alignment equipment. The acceptable
range is -1° to +1°. Refer to the Specifications chart.
Road test the vehicle and observe the steering
wheel return-to-center position. Before road testing,
check
and
correct
the tire
inflation pressures. Inflate
both
of the front tires
with exactly the
same
pressure.
During the road test, make vehicle turns to both
the left and right. If the steering wheel returns to­
ward the center position unassisted, the caster angle is correct. However, if the steering wheel does not re­ turn toward the center position unassisted, an incor­
rect caster angle is probable.
(1) The caster angle is factory preset at positive
two degrees
(
+
2°).
The acceptable range is +1/2° to +
3
1/2°.
(2) The caster angle should be measured with ac­
curate wheel alignment equipment.
(3) Caster angle can be adjusted by installing ta­
pered shims between the front axle pads and the spring brackets. The caster angle should be adjusted
as near as possible to the preferred angle.
(4) Record the caster measurement before remov­
ing the original shims from the spring pads.
(5) The caster should be the same at both sides of
the vehicle. Refer to the Specifications chart.

WHEEL TOE POSITION The wheel toe position adjustment should be the fi­
nal front wheel alignment adjustment. In all in­ stances, follow the equipment manufacturer's
recommended procedure.
(1) Secure the steering wheel with the front wheels
in the straight-ahead position. For vehicles equipped
with power steering, start the engine before straight­ ening the wheels.
With power steering, the engine should be op­
erating during the wheel toe position adjust­
ment.
(2) Loosen the tie rod adjustment sleeve clamp
bolts (Fig. 3).
(3) Adjust the wheel toe position by rotating the
tie rod adjustment sleeve (Fig. 3). Rotate each tie-rod end in the direction of
sleeve rotation during the adjustment (Fig. 3).
This will ensure that both tie-rod ends are at the center of their travel.
(4) If applicable, turn the ignition switch off.
