front or side oil seal. Scored, battered or
excessively wor n sliding surface of com-
panion flange.
Correct or replace.

2. Seizure
NOTE:Seized or damaged parts should be re-
placed, and also other parts should be thor-
oughly 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 speci-
fied 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 re-
paired 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 hypoid
driven gear bolt
Retighten.
(5) Damage due to overloading. Replace.
4. Noises when starting or shifting
gears
NOTE:
Noises may be caused by differential as-
sembly, universal joint, wheel bearing, etc.
Find out what is actually making noise be-
fore disassembling.
(1) Excessive backlash for hypoid gear. Readjust.
(2) Excessive backlash for differential
gear.
Replace the differential case assembly.
(3) Insufficient preload for front or rear
bearing.
Readjust.
(4) Loose drive pinion nut. Tighten to the specified torque.
(5) Loose bolts and nuts such as side
bearing retainer attaching bolt.

(3) Broken pinion mate shaft. Replace the differential case assembly.
(4) Seized or damaged side bearing. Replace.
6. Gear Noise
NOTE:
Since noises from engine, muffler, trans-
mission, 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, accelerat-
ing, cruising, and jacking-up all four wheels.
Perform these inspections according to the
condition of trouble. When listening to nois-
es, shift gears into four wheel drive and
fourth speed position, trying to pick up only
differential noise.

bearing.
Replace.
(8) Differential carrier is vibrating. Replace the differential case assembly.

3) Remove the strut mount, spacer and upper
spring seat from strut.
4) Gradually decrease the compression force of
compressor, and remove the coil spring.
5) Remove the dust cover and helper spring.
D: ASSEMBLY
1) Before installing the coil spring, strut mount, etc.
on strut, check for the presence of air in the damp-
ening force generating mechanism of the strut
since air prevents proper dampening force produc-
tion.
2) Checking for presence of air
(1) Place the strut vertically with the piston rod
facing up.
(2) Move the piston rod to the center of its entire
stroke.
(3) While holding the piston rod end with fin-
gers, move the rod up and down.
(4) If the piston rod moves more than 10 mm
(0.39 in) in the former step, purge air from the
strut.
3) Air purging procedure
(1) Place the strut vertically with the piston rod
facing up.
(2) Fully extend the piston rod.
(3) With the piston rod fully extended, place the
piston rod side down. The strut must stand ver-
tically.
(4) Fully retract the piston rod.
(5) Repeat 3 or 4 times from the step (1).
NOTE:
After purging air from the strut, be sure to place the
strut with the piston rod facing up. If the strut is laid
down for any reason, check for the entry of air in ac-
cordance with “Checking for presence of air”
4) Using a coil spring compressor, compress the
coil spring.
NOTE:
Make sure that the vertical install direction of the
coil spring is as shown in the figure.
5) Set the coil spring correctly so that its end face
seats well in the spring seat as shown in the figure.
6) Install the helper and dust cover to the piston
rod.

NOTE:
Position the upper spring seat as shown in the fig-
ure.
8) Install spacer and the strut mount to piston rod,
and tighten a new self-locking nut temporarily.

10) Loosen the coil spring carefully.
E: INSPECTION
Check the removed part for wear, damage and
cracks, and then repair or replace it if defective.
1. DAMPER STRUT
1) Check for oil leaks.
2) Move the piston rod up and down to check that it
operates smoothly without any hitch.
3) Piston rod play
•Measure the play as follows:
Fix the outer shell in place and fully extend the rod.
Set a dial gauge at the end of rod L [10 mm (0. 39
in)], and then read the dial gauge indication P1while applying a force of W [20 N (2 kgf, 4 lb)] to the
threaded portion. Apply a force of 20 N (2 kgf, 4 lb)
from the opposite direction of “W”, and then read
the dial gauge indication P2.
Play limit (P1 + P2):
0.8 mm (0.031 in)
If the play exceeds limit, replace the strut.
2. STRUT MOUNT
Check the rubber part for deformation, cracks or
deterioration, and then replace it with a new one if
defective.
3. DUST COVER
If any cracks or damage are found, replace it with a
new one.
4. COIL SPRING
If a permanent strain is found, replaced it with a
new part.
5. HELPER
Replace it with a new one if cracked or damaged.

1) Lift-up the vehicle.
2) If a fluid leak is found, clean the fluid completely
from the suspect area, and turn the steering wheel
approx. 30 to 40 times to the left and right from lock
to lock, with the engine running, and check again
for leaks immediately, and also after a few hours
have passed.
3) Cause and solution for oil leakage from “a”
The oil seal is damaged. Replace the valve assem-
bly with a new one.
4) Cause and solution for oil leakage from “b”.
The torsion bar O–ring is damaged. Replace the
valve assembly with a new one.
5) Cause and solution for oil leakage from “c”.
The oil seal is damaged. Replace the valve assem-
bly or oil seal with a new one.
6) Cause and solution for oil leakage from “d”.
The pipe is damaged. Replace the faulty pipe or O-
ring.
7) Cause and solution for oil leakage from “g”.
The hose is damaged. Replace the hose with a
new one.
8) If leak is other than a, b, c, d or g, or if oil is leak-
ing from gearbox, move the right and left boots to-
ward tie-rod end side, respectively, with the
gearbox mounted to the vehicle, and remove fluid
from surrounding portions. Then, turn the steering
wheel from lock to lock about thirty to forty times
with the engine running, and make comparison of
the leaked portion immediately after and several
hours after this operation.
(1) Leakage from “e”
The cylinder seal is damaged. Replace the rack
bushing with a new one.
(2) Leakage from “f”
There are two possible causes. Perform the fol-
lowing step first. Remove the pipe assembly B
from the valve housing, and close the circuit us-
ing ST.
ST 926420000 PLUG
Turn the steering wheel from lock to lock ap-
prox. 30 to 40 times with the engine running,
then inspect the leaked portion immediately af-
ter and several hours after this operation.
•If leakage from “f” is noted again:
The oil seal of pinion & valve assembly is dam-
aged. Replace the pinion & valve assembly with a
new one. Or replace the oil seal and the parts that
are damaged during disassembly with new ones.
•If oil stops leaking from “f”:
The oil seal of rack housing is damaged. Replace
the oil seal and parts that are damaged during dis-
assembly with new ones.
F: ADJUSTMENT
1) Adjust the front toe.
Standard of front toe:
IN 3 — OUT 3 mm (IN 0.12 — OUT 0.12 in)
2) Adjust the steering angle of the wheels.
Specification of steering angle:
3) If the steering wheel spokes are not horizontal
when wheels are set in the straight ahead position,
or error is more than 5° on the periphery of the
steering wheel, correctly re-install the steering
wheel.
4) If the steering wheel spokes are not horizontal
with vehicle set in the straight ahead position after
this adjustment, correct it by turning the right and
left tie–rods in the opposite direction from each oth-
er by the same angle.
