Removal and InstallationADS000C7
REMOVAL
1. Remove tire with power tool.
2. Remove cotter pin. Then remove lock nut from drive shaft.
3. Remove fixing nuts and bolts between side flange and drive shaft with power tool.
4. Separate drive shaft from wheel hub and bearing assembly by lightly tapping the end with a suitable ham-
mer and wood block. If it is hard to separate, use a suitable puller.
5. Remove drive shaft from axle.
CAUTION:
When removing drive shaft, do not apply an excessive angle to drive shaft joint. Also be careful
not to excessively extend slide joint.
INSPECTION AFTER REMOVAL

Move joint up/down, left/right, and in the axial direction. Check
for any rough movement or significant looseness.

Check boot for cracks or other damage, and also for grease
leakage.

If a trouble is found, disassemble drive shaft, and then replace
with new one.
INSTALLATION
Refer to RAX-9, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AIS003AR
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions AIS003AS

Disconnect both battery cables in advance.

Do not tamper with or force air bag lid open, as this may adversely affect air bag performance.

Be careful not to scratch pad and other parts.

When removing or disassembling any part, be careful not to damage or deform it. Protect parts, which
may get in the way with cloth.

When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.

Keep removed parts protected with cloth.

If a clip is deformed or damaged, replace it.

If an unreusable part is removed, replace it with a new one.

Tighten bolts and nuts firmly to the specified torque.

After re-assembly has been completed, make sure each part functions correctly.

Remove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Then wipe the area with a soft dry cloth.

Do not use any organic solvent, such as thinner or benzine.

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.

5. Adjust clearance between rear face of side gear and thrust
washer by selecting side gear thrust washer. Refer to RFD-31,
"AVAILABLE PINION HEIGHT ADJUSTING WASHERS" .
Use two feeler gauges to prevent leaning of side gear as show-
ing figure.
SIDE BEARING PRELOAD
A selection of 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 carrier.
4. Install the side bearing caps in their correct locations and torque
the bearing cap retaining bolts.
5. Turn the carrier several times to seat the bearings.Clearance between side gear thrust washer and dif-
ferential case

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

Installation of J34309-9 and J34309-16; place a suitable 2.5 mm (0.098 in) thick plain washer between
J34309-9 and J34309-16. Both surfaces of J34309-9 and J34309-16 must be parallel with a clearance of
2.5 mm (0.098 in).
3. Install the pinion rear bearing inner race into the final drive hous-
ing. Then place the pinion preload shim selector tool, J34309-1,
gauge screw assembly.
4. Assemble the pinion front bearing inner race and the J34309-2
gauge anvil. Assemble them together with the J34309-1 gauge
screw in the final drive housing. Make sure that the pinion height
gauge plate, J34309-16, will turn a full 360 degrees. Tighten the
two sections together by hand.
5. Turn the assembly several times to seat the bearings.
6. Measure the turning torque at the end of the J34309-2 gauge
anvil using torque wrench J-25765A.
