Symptom and possible cause Remedy
4. Broken differential (case, gear, bearing, etc.)
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 broken components and
at the same time check other components for any trouble,
and replace if necessary.
(b) Use of vehicle under severe conditions such as excessive
load and improper use of clutchReadjust bearing preload and backlash and face contact of
gears.
(c) Improper adjustment of taper roller bearing Adjust.
(d) Improper adjustment of drive pinion and hypoid driven
gearAdjust.
(e) Excessive backlash due to worn differential side gear,
washer or differential pinionAdd recommended oil to specified level. Do not use vehicle
under severe operating conditions.
(f) Loose hypoid driven gear clamping bolts Tighten.
5. 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.
(1) Gear noise when driving: If noise increases as vehicle speed increases it may be due to insufficient gear oil, incorrect
gear engagement, damaged gears, etc.
(2) Gear noise when coasting: Damaged gears due to maladjusted bearings and incorrect shim adjustment
(3) Bearing noise when driving or when coasting: Cracked, broken or damaged bearings
(4) Noise which mainly occurs when turning: 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 pinion Replace as a set.
Readjust bearing preload.
(d) Loose roller bearing Readjust hypoid driven gear to drive pinion backlash and
check tooth contact.
(e) Distorted hypoid driven gear or differential case Replace.
(f) Worn washer and differential pinion shaft Replace.

A: INSPECTION
1. ATF LEVEL
1) Raise ATF temperature to 60 to 80°C (140 to 176°F)
from 40 to 60°C (104 to 140°F) (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 atten-
tion to the fluid temperature when checking oil level.
2) Make sure the vehicle is level. After selecting all posi-
tions (P, R, N, D, 3, 2, 1), set the selector leveler in“P”
range. Measure fluid level with the engine idling.
NOTE:
After running, idle the engine for one or two minutes 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 range (above the center
between upper and lower marks). When the transmission
is hot, the level should be above the center of upper and
lower marks, and when it is cold, the level should be found
below the center of these two marks.
CAUTION:
Use care not to exceed the upper limit level.
ATF level varies with temperature. Remember that
the addition of fluid to the upper limit mark when the
transmission is cold will result in the overfilling of
fluid.
4) Fluid temperature rising speed
By idling the engine
Time for temperature rise to 60°C (140°F) with atmo-
spheric temperature of 0°C (32°F): More than 25 minutes

Time for temperature rise to 30°C (86°F) with atmo-
spheric temperature of 0°C (32°F): Approx. 8 minutes
By running the vehicle
Time for temperature rise to 60°C (140°F) with atmo-
spheric temperature of 0°C (32°F): More than 10 minutes
5) Method for checking fluid level upon delivery or at peri-
odic inspection
Check fluid level after a warm-up run of approx. 10 min-
utes. During the warm-up period, the automatic transmis-
sion functions can also be checked.

1) Feed the specified fluid with its level being about 5 cm
(2.0 in) lower than the mouth of tank.
2) Continue to turn steering wheel slowly from lock to lock
until bubbles stop appearing in the tank while keeping the
fluid at that level.
3) In case air is absorbed to deliver bubbles into piping
because the fluid level is lower, leave it about half an hour
and then do the step 2) all over again.
4) Start, and idle the engine.
5) Continue to turn steering wheel slowly from lock to lock
again until bubbles stop appearing in the tank while keep-
ing the fluid at that level.
It is normal that bubbles stop appearing after three times
turning of steering wheel.
6) In case bubbles do not stop appearing in the tank, leave
it about half an hour and then do the step 5) all over again.
7) Stop the engine, and take out safety stands after jack-
ing up vehicle again.
Then lower the vehicle, and idle the engine.
8) Continue to turn steering wheel from lock to lock until
bubbles stop appearing and change of the fluid level is
within 3 mm (0.12 in).
9) In case the following happens, leave it about half an
hour and then do step 8) again.
(1) The fluid level changes over 3 mm (0.12 in).
(2) Bubbles remain on the upper surface of the fluid.
(3) Grinding noise is generated from oil pump.

*1 If tires and/or rims are wider, the load to power steering system is the more. Accordingly, in a
condition, for example before fluid warms-up, relief valve may work before maximum turning angle.
In this case, steering effort may be heavy. When measured hydraulic pressure is normal, there is
no abnormal thing.
*2 In cold weather, steering effort may be heavy due to increased flow resistance of cold fluid. After
warming up engine, turn steering wheel from stop to stop several times to warm up fluid. Then if
steering effort reduces normally, there is no abnormal thing.
*3 In cold weather or with insufficient warm-up of engine, steering effort may be heavy due to exces-
sive drop of idling when turning steering wheel. In this case, it is recommended to start the vehicle
with increasing engine speed than usual. Then if steering effort reduces normally, there is no
abnormal thing. Measure hydraulic pressure.

3. Tools and Equipment
The following section provides information about the tools
and equipment that will be necessary to properly service
the A/C system.
Since equipment may vary slightly depending on the
manufacturer, it is important to always read and follow the
manufacturer’s instructions.
CAUTION:
When working on vehicles with the HFC-134a system,
only use HFC-134a specified tools and parts. Do not
mix with CFC-12 tools and parts. If HFC-134a and
CFC-12 refrigerant or compressor oil is mixed, poor
lubrication will result and the compressor itself may be
destroyed.
In order to help prevent mixing HFC-134a and CFC-12
parts and liquid, the tool and screw type and the type
of service valves used are different. The gas leak
detectors for the HFC-134a and CFC-12 systems must
also not be interchanged.

3. DEEP DAMAGE SUCH AS A BREAK OR HOLE
THAT REQUIRES FILLING
Much of the peripheral grained surface must be sacrificed
for repair, and the degree of restoration is not really worth
the expense. (The surface, however, will become almost
flush with adjacent areas.)

2 Parts removal Remove parts built into bumper as required.
3 Bumper placementPlace bumper on a paint work table as required.
It is recommended that contour of work table

4 Surface preparationRemove dust, oil, etc. from areas to be repaired and surrounding areas, using a suitable solvent
(NRM No. 900 precleno, white gasoline, or alcohol).
5 CuttingIf nature of damage are cracks or holes, cut a
guide slit of 20 to 30 mm (0.79 to 1.18 in) in
length along the crack or hole up to the bumper’s
base surface. Then, bevel or“vee-out”the
affected area using a knife or grinder.

6 Sanding (I) Grind beveled surface with sand paper (#40 to #60) to smooth finish.
7 Cleaning Clean the sanded surface with the same solvent as used in process No. 4.
8 Temporary weldingGrind the side just opposite the beveled area with sand paper (#40 to #60) and clean using a sol-
vent.
Temporarily spot-weld the side, using a PP welding rod and heater gun.
G5M0166
NOTE:

Do not melt welding rod until it flows out. This results in reduced strength.

Leave the welded spot unattended until it cools completely.
