Transmission Gear Oil
2. Transmission Gear Oil
A: INSPECTION
1) Park the vehicle on a level surface.
2) Turn the ignition switch to OFF, and wait until the
engine cools.
3) Remove the oil level gauge and wipe it clean.
4) Reinsert the level gauge all the way. Be sure that
the level gauge is correctly inserted and in the
proper direction.
5) Pull out the oil level gauge again and check the
oil level on it. If it is below the lower level, add oil
through the oil level gauge hole to bring the level up
to the upper level.
B: REPLACEMENT
1) Pull out the oil level gauge.
2) Lift-up the vehicle.
3) Drain the transmission gear oil completely.
CAUTION:
 Directly after the engine has been running,
the transmission gear oil is hot. Be careful not
to burn yourself.
 Be sure not to spill the transmission gear oil
on exhaust pipe to prevent it from emitting
smoke or firing. When the transmission gear oil
is split on exhaust pipe, wipe it away complete-
ly.4) Tighten the transmission gear oil drain plug us-
ing a new gasket.
Tightening torque:
44 N·m (4.5 kgf-m, 32.5 ft-lb) (Aluminum gas-
ket)
70 N·m (7.1 kgf-m, 51.6 ft-lb) (Copper gasket)
5) Lower the vehicle.
6) Pour gear oil into the gauge hole.
Recommended gear oil:
Use GL-5 (75 W — 90) or equivalent.
Gear oil capacity:
Single-range model;
Model without oil pump
3.52 (3.7 US qt, 3.1 Imp qt)
Model with oil pump
3.92 (4.1 US qt, 3.4 Imp qt)
Dual-range model;
4.02 (4.2 US qt, 3.5 Imp qt)
7) Measure the level of transmission gear oil, and
then check the level within the specified range.
CAUTION:
When inserting the level gauge into transmis-
sion gear, align the protrusion on the side of
the top part of level gauge with the notch in the
gauge hole.

5. Oil Seal
A: INSPECTION
Check the oil seal portion for leakage. If leakage is
found, replace the oil seal with a new one.
B: REPLACEMENT
1) Clean the transmission exterior.
2) Drain the gear oil completely.
3) Replace the gasket with a new one, and then
tighten the drain plug after draining gear oil.

2. DIFFERENTIAL
Symptom Possible cause Remedy
1. Broken differential (case, gear, bear-
ing, etc.)
N
OTE:
Noise will develop and finally it will be-
come impossible to continue to run due to
broken pieces obstructing the gear revo-
lution. (a) Insufficient or improper oil Disassemble the differential and replace
broken 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 clutch Readjust the bearing preload and back-
lash and face contact of gears.
(c) Improper adjustment of taper roller
bearingAdjust.
(d) Improper adjustment of drive pinion
and hypoid driven gear Adjust.
(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 the vehicle under severe oper-
ating 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, bear-
ing, 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.
 Gear 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.
 Gear noise when coasting: Damaged
gears due to maladjusted bearings and
incorrect shim adjustment
 Bearing noise when driving or when
coasting: Cracked, broken or damaged
bearings
 Noise 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 the bearing preload.
(d) Loose roller bearing Readjust the hypoid driven gear to drive
pinion backlash and check tooth contact.
(e) Distorted hypoid driven gear or differ-
ential caseReplace.
(f) Worn washer and differential pinion
shaftReplace.
