2. Differential
Symptom Possible cause Remedy
1. Broken differential (case, gear,
bearing, etc.)
NOTE:
Abnormal noise will develop and finally it
will become impossible to continue to
run due to broken pieces obstructing the
gear revolution.(a) Insufficient or improper oil Disassemble differential and replace bro-
ken components and at the same time
check other components for any trouble,
and replace if necessary
(b) Use of vehicle under severe condi-
tions such as excessive load and
improper use of clutchReadjust bearing preload and backlash
and face contact of gears.
(c) Improper adjustment of taper roller
bearingAdjust.
(d) Improper adjustment of drive pinion
and hypoid driven gearAdjust.
(e) Excessive backlash due to worn dif-
ferential side gear, washer or differential
pinion vehicle under severe operating
conditions.Add recommended oil to specified level.
Do not use vehicle under severe operat-
ing conditions.
(f) Loose hypoid driven gear clamping
boltsTighten.
2. Differential and hypoid gear noises
Troubles of the differential and hypoid
gear always appear as noise problems.
Therefore noise is the first indication of
the trouble. However noises from the
engine, muffler, tire, exhaust gas,
bearing, body, etc. are easily mistaken
for the differential noise. Pay special
attention to the hypoid gear noise
because it is easily confused with other
gear noises. There are the following four
kinds of noises.
IGear noise when driving: If noise
increases as vehicle speed increases it
may be due to insufficient gear oil, incor-
rect gear engagement, damaged gears,
etc.
IGear noise when coasting: Damaged
gears due to maladjusted bearings and
incorrect shim adjustment
IBearing noise when driving or when
coasting: Cracked, broken or damaged
bearings
INoise which mainly occurs when turn-
ing: Unusual noise from differential side
gear, differential pinion, differential pinion
shaft, etc.(a) Insufficient oil Lubricate.
(b) Improper adjustment of hypoid driven
gear and drive pinionCheck tooth contact.
(c) Worn teeth of hypoid driven gear and
drive pinionReplace as a set.
Readjust bearing preload.
(d) Loose roller bearing Readjust hypoid driven gear to drive pin-
ion backlash and check tooth contact.
(e) Distorted hypoid driven gear or differ-
ential caseReplace.
(f) Worn washer and differential pinion
shaftReplace.

1. General
A: PRECAUTION
When disassembling or assembling the automatic
transmission, observe the following instructions.
1) Workshop
Provide a place that is clean and free from dust.
Principally the conventional workshop is suitable
except for a dusty place. In a workshop where
grinding work, etc. which produces fine particles is
done, make independent place divided by the vinyl
curtain or the equivalent.
2) Work table
The size of 1 x 1.5 m (40 x 60 in) is large enough
to work, and it is more desirable that its surface be
covered with flat plate like iron plate which is not
rusted too much.
3) Cleaning of exterior
(1) Clean the exterior surface of transmission
with steam and/or kerosene prior to
disassembly, however it should be noted that
vinyl tape be placed on the air breather or oil
level gauge to prevent infiltration of the steam
into the transmission and also the cleaning job
be done away from the place of disassembly
and assembly.
(2) Partial cleaning will do, depending on the
extent of disassembly (such as when disassem-
bly is limited to some certain parts).
4) Disassembly, assembly and cleaning
(1) Disassemble and assemble the transmis-
sion while inspecting the parts in accordance
with the Diagnostics.
(2) During job, do not use gloves. Do not clean
the parts with rags: Use chamois or nylon cloth.
(3) Pay special attention to the air to be used
for cleaning. Get the moisture and the dust rid
of the air as much as possible. Be careful not to
scratch or dent any part while checking for
proper operation with an air gun.
(4) Complete the job from cleaning to comple-
tion of assembly as continuously and speedily
as possible in order to avoid occurrence of sec-
ondary troubles caused by dust. When stopping
the job unavoidably cover the parts with clean
chamois or nylon cloth to keep them away from
any dust.
(5) Use kerosene, white gasoline or the equiva-
lent as washing fluid. Use always new fluid for
cleaning the automatic transmission parts and
never reuse. The used fluid is usable in disas-
semble and assemble work of engine and
manual transmission.
(6) Although the cleaning should be done by
dipping into the washing fluid or blowing of the
pressurized washing fluid, the dipping is more
desirable. (Do not rub with a brush.) Assemblethe parts immediately after the cleaning without
exposure to the air for a while. Besides in case
of washing rubber parts, perform the job quickly
not to dip them into the washing fluid for long
time.
(7) Apply the automatic transmission fluid
(ATF) onto the parts immediately prior to
assembly, and the specified tightening torque
should be observed carefully.
(8) Use vaseline if it is necessary to hold parts
in the position when assembling.
(9) Drain ATF and differential gear oil into a
saucer so that the conditions of fluid and oil can
be inspected.
(10) Do not support axle drive shaft, stator
shaft, input shaft or various pipes when moving
transmission from one place to another.
(11) Always discard old oil seals and O-ring,
and install new ones.
(12) Always discard old oil seals and O-ring,
and install new ones.
(13) Be sure to replace parts which are
damaged, worn, scratched, discolored, etc.
B: INSPECTION
1. ATF LEVEL
1) Raise ATF temperature to 60 to 80ÉC (140 to
176ÉF) from 40 to 60ÉC (104 to 140ÉF) (when cold)
by driving a distance of 5 to 10 km (3 to 6 miles).
NOTE:
The level of ATF varies with fluid temperature. Pay
attention to the fluid temperature when checking oil
level.

2) Make sure the vehicle is level. After selecting all
positions (P, R, N, D, 3, 2, 1), set the selector lev-
eler in ªPº range. Measure fluid level with the
engine idling.
NOTE:
After running, idle the engine for one or two min-
utes before measurement.
3) If the fluid level is below the center between
upper and lower marks, add the recommended
ATF until the fluid level is found within the specified
