3. FLYWHEEL
CAUTION:
Since this bearing is grease sealed and is of a
nonlubrication type, do not wash with gasoline
or any solvent.
1) Damage of facing and ring gear
If defective, replace flywheel.
G2M0250
2) Smoothness of rotation
Rotate ball bearing applying pressure in thrust
direction.3) If noise or excessive play is noted, replace ball
bearing as follows:
(1) Drive out ball bearing from flywheel.
(2) Press bearing into flywheel until bearing
end surface is flush with clutch disc contact sur-
face of flywheel. Do not press inner race.

(6) Wear, damage or incorrectly fitting for spindle,
side retainer and oil seal.Repair or replace.
2. Seizure
NOTE:
Seized or damaged parts should
be replaced, and also other parts
should be thoroughly checked for
any defect and should be repaired
or replaced as required.(1) Insufficient backlash for hypoid gear. Readjust or replace.
(2) Excessive preload for side, rear, or front bearing. Readjust or replace.
(3) Insufficient or improper oil used. Replace seized part and fill with
specified oil to specified level.
3. Damage
NOTE:
Damaged parts should be
replaced, and also other parts
should be thoroughly checked for
any defect and should be repaired
or replaced as required.(1) Improper backlash for hypoid gear. Replace.
(2) Insufficient or excessive preload for side, rear, or
front bearing.Readjust or replace.
(3) Excessive backlash for differential gear. Replace gear or thrust washer.
(4) Loose bolts and nuts such as crown gear bolt. Retighten.
(5) Damage due to overloading. Replace.
4. Noises when starting or shift-
ing gears
NOTE:
Noises may be caused by differen-
tial assembly, universal joint, wheel
bearing, etc. Find out what is actu-
ally making noise before disassem-
bly.(1) Excessive backlash for hypoid gear. Readjust.
(2) Excessive backlash for differential gear. Replace gear or thrust washer.
(3) Insufficient preload for front or rear bearing. Readjust.
(4) Loose drive pinion nut. Tighten to specified torque.
(5) Loose bolts and nuts such as side bearing
retainer attaching bolt.Tighten to specified torque.
5. Noises when cornering(1) Damaged differential gear. Replace.
(2) Excessive wear or damage of thrust washer. Replace.
(3) Broken pinion mate shaft. Replace.
(4) Seized or damaged side bearing. Replace.
6. Gear noises
NOTE:
Since noises from engine, muffler,
transmission, propeller shaft, wheel
bearings, tires, and body are
sometimes mistaken for noises
from differential assembly, be care-
ful in checking them. Inspection
methods to locate noises include
coasting, accelerating, cruising,
and jacking-up all four wheels.
Perform these inspections accord-
ing to condition of trouble. When
listening to noises, shift gears into
four wheel drive and fourth speed
position, trying to pick up only dif-
ferential noise.(1) Improper tooth contact of hypoid gear. Readjust or replace hypoid gear
set.
(2) Improper backlash for hypoid gear. Readjust.
(3) Scored or chipped teeth of hypoid gear. Replace hypoid gear set.
(4) Seized hypoid gear. Replace hypoid gear set.
(5) Improper preload for front or rear bearings. Readjust.
(6) Seized, scored, or chipped front or rear bearing. Replace.
(7) Seized, scored, or chipped side bearing. Replace.
(8) Vibrating differential carrier. Replace.

2. CAMBER (FRONT AND REAR)
IInspection
1) Place front wheel on turning radius gauge.
Make sure ground contacting surfaces of front and
rear wheels are set at the same height.
2) Set ST into the center of the wheel, and then
install the wheel alignment gauge.

NOTE:
Refer to the ªSPECIFICATIONS AND SERVICE
DATAº for the camber values.
IFront Camber Adjustment
1) Loosen two self-locking nuts located at lower
front portion of strut.
CAUTION:
IWhen adjusting bolt needs to be loosened or
tightened, hold its head with a wrench and turn
self-locking nut.
IDiscard loosened self-locking nut and
replace with a new one.2) Turn camber adjusting bolt so that camber is
set at the specification.
NOTE:
Moving the adjusting bolt by one scale graduation
changes camber by approximately 0É10¢.

5. REAR WHEEL TOE-IN
IInspection
1) Using a toe-in gauge, measure rear wheel toe-
in.
Toe-in:
0
±3mm(±0.12 in)
2) Mark rear sides of left and right tires at height
corresponding to center of spindles and measure
distance ªBº between marks.
3) Move vehicle forward so that marks line up with
front sides at height corresponding to center of
spindles.
4) Measure distance ªAº between left and right
marks. Toe-in can then be obtained by the follow-
ing equation:
B þ A = Toe-in

IAdjustment
1) Loosen self-locking nut on inner side of rear
lateral link.
CAUTION:
IWhen loosening or tightening adjusting bolt,
hold bolt head and turn self-locking nut.
IDiscard loosened self-locking nut and
replace with a new one.
G4M0486
2) Turn adjusting bolt head until toe-in is at the
specification.
NOTE:
When left and right wheels are adjusted for toe-in
at the same time, the movement of one scale
graduation changes toe-in by approximately 3 mm
(0.12 in).
