PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
PRECAUTIONSPFP:00001
PrecautionsADS000K2
CAUTION:

Before starting diagnosis of the vehicle, understand symptoms well. Perform correct and system-
atic operations.

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

Carry out an overhaul in a clean work place, Using a dust proof room is recommended.

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

Check appearance of the disassembled parts for damage, deformation, and abnormal wear. If a
malfunction is detected, replace it with a new one.

Normally replace lock pins, oil seals, and bearings with new ones every times they are removed.

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

Clean and flush the parts sufficiently and blow them dry.

Be careful not to damage the sliding surfaces and mating surface.

When applying sealant, remove the old sealant from the mounting surface; then remove any mois-
ture, 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 a shop cloth to prevent entering of lint.

During assembly, observe the specified tightening torque, and new differential gear oil, Vaseline,
or multi-purpose grease, as specified for each vehicle, when necessary.

REMOVAL
1. Remove the rear propeller shaft. Refer to PR-8, "REMOVAL" .
2. Put a matching mark on the end of the drive pinion correspond-
ing to the C position matching mark on the final drive companion
flange.
CAUTION:

For matching mark, use paint. Never damage drive pin-
ion.

The matching mark C on the final drive companion flange
indicates the maximum vertical runout position.
3. Using the drive pinion flange wrench, remove drive pinion lock
nut.
4. Remove the companion flange using the puller.
5. Remove front oil seal using the side bearing outer race puller,
INSTALLATION
1. Apply multi-purpose grease to sealing lips of oil seal. Press front
oil seal into carrier with tool.
NOTE:

When installing the oil seal, be careful not to get it inclined.

Discard the old oil seal. Always replace with new one.

6. Measure the turning torque of the carrier at the drive gear retain-
ing bolts with a spring gauge, J-8129.
7. If the turning torque is not within the specifications, correct the
torque as follows:

If the turning torque is less than the specified range, install
washers of greater thickness.

If the turning torque is greater than the specification, install
thinner washers.

See the SDS section for washer dimensions and part num-
bers.
8. Record the total amount of washer thickness required for the
correct carrier side bearing preload.
9. Remove the carrier from the final drive housing. Save the
selected washers for later use during the assembly of the final
drive unit.
PINION GEAR HEIGHT
1. Make sure all parts are clean and that the bearings are well
lubricated.
2. Assemble the pinion gear bearings into the differential shim
selector tool, J34309.

Pinion front bearing; make sure the J34309-3 pinion front bear-
ing seat is secured tightly against the J34309-2 gauge anvil.
Then turn the pinion front bearing pilot, J34309-5, to secure the
bearing in its proper position.

Pinion rear bearing; the pinion rear bearing pilot, J34309-8, is
used to center the pinion rear bearing only. The pinion rear bear-
ing locking seat, J34309-4, is used to lock the bearing to the
assembly.Specification
