PRECAUTIONS
Revision: 2007 April2007 M35/M45
PRECAUTIONSPFP:00001
Service Notice or PrecautionsNDS000EY

Check for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.

Overhaul should be done in a clean work area, it is preferable to work in dustproof area.

Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.

Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.

Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.

In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.

Clean and flush the parts sufficiently and blow-dry them.

Be careful not to damage sliding surfaces and mating surfaces.

When applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.

Always use shop paper for cleaning the inside of components.

Avoid using cotton gloves or shop rags to prevent entering of lint.

During assembly, observe the specified tightening torque, and apply new gear oil, petroleum jelly, or multi-
purpose grease as specified for each vehicle, if necessary.

7. Remove bearing caps.
8. Lift differential case assembly out with a suitable tool.

Keep side bearing outer races together with inner race. Do
not mix them up.
Also, keep side bearing adjusting washers together with bear-
ings.
9. Remove side bearing inner race.
To prevent damage to bearing, engage puller jaws in groove
().
CAUTION:

To prevent damage to the side bearing and drive gear,
place copper plates between these parts and vise.

It is not necessary to remove side bearing inner race
except it is replaced.

11. Tap pinion front/rear bearing outer races uniformly a brass rod or
equivalent to removed.
CAUTION:
Be careful not to damage gear carrier.
INSPECTION AFTER DISASSEMBLY
Clean up the disassembled parts. Then, inspect if the parts are worn or damaged. If so, follow the measures
below.
ADJUSTMENT AND SELECTION OF ADJUSTING WASHERS
Differential Side Gear Clearance

Assemble the differential parts if they are disassembled. Refer to RFD-33, "Differential Assembly" .
1. Place differential case straight up so that side gear to be mea-
sured comes upward.
SDIA0817E
Content Conditions and Measures
Hypoid gear

If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-
essary.

If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new
drive gear and drive pinion as a set.
Bearing

If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing
is observed, replace as a bearing assembly (as a new set).
Side gear and Pinion mate
gear

If any cracks or damage on the surface of the tooth is found, replace.

If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
Side gear thrust washer and
pinion mate thrust washer

If it is chipped (by friction), damaged, or unusually worn, replace.
Oil seal

Whenever disassembled, replace.

If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace
them.
Differential case

If any wear or crack on the contact sides of the differential case is found, replace.
Companion flange

If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the
companion flange is found, replace.

2. Using feeler gauge, measure the clearance between side gear
back and differential case at 3 different points, while rotating
side gear. Average the 3 readings, and then measure the clear-
ance of the other side as well.
CAUTION:
To prevent side gear from tilting, insert feeler gauges with
the same thickness from both sides.
3. If the back clearance is outside the specification, use a thicker/
thinner side gear thrust washer to adjust. Refer to RFD-38,
"Side Gear Thrust Washer" .
CAUTION:
Select a side gear thrust washer for right and left individu-
ally.
Side Bearing Preload

Selecting carrier side bearing adjusting washers is required for successful completion of this procedure.
1. Make sure all parts are clean. Also, make sure the bearings are
well lubricated with gear oil.
2. Place the differential case, with side bearings and bearing races
installed, into gear carrier.
3. Insert left and right original side bearing adjusting washers in
place between side bearings and gear carrier.Side gear back clearance specification:
0.2 mm (0.008 in) or less.
(Each gear should rotate smoothly without excessive
resistance during differential motion.)
When the back clearance is large:
Use a thicker thrust washer.
When the back clearance is small:
Use a thinner thrust washer.
