3. Screw the drive shaft puller (suitable tool) 30 mm (1.18 in) or
more onto the thread on joint sub-assembly, and pull joint sub-
assembly out of shaft.
CAUTION:

INSPECTION AFTER DISASSEMBLY
Shaft
Check shaft for runout, cracks, or other damage. Replace if there are.
Joint Sub-Assembly (Wheel Side)
Check the following:

Joint sub-assembly for rough rotation and excessive axial looseness.

The inside of the joint sub-assembly for entry of foreign material.

Joint sub-assembly for compression scars, cracks, and fractures inside of joint sub-assembly.
Replace joint sub-assembly if there are any non-standard conditions of components.
Housing and Spider assembly (Front Final Drive side)
Replace housing and spider assembly if there is scratching or wear of housing roller contact surface or spider
roller contact surface.
NOTE:

PRECAUTIONS
Revision: 2007 April2007 M35/M45
PRECAUTIONSPFP:00001
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectNDS000EK
NOTE:

This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).

Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.

Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-III.
Service Notice or PrecautionsNDS000EL

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.

Changing Differential Gear OilNDS000EQ
DRAINING
1. Stop engine.
2. Remove drain plug (1) and drain gear oil.
3. Set a gasket on drain plug (1) and install it to final drive assem-
bly and tighten to the specified torque. Refer to FFD-15, "
COM-
PONENTS" .
CAUTION:
Do not reuse gasket.
FILLING
1. Remove filler plug (1). Fill with new gear oil until oil level reaches
the specified level near filler plug mounting hole.
2. After refilling oil, check oil level. Set a gasket to filler plug (1),
then install it to final drive assembly. Refer to FFD-15, "
COMPO-
NENTS" .
CAUTION:
Do not reuse gasket.
Checking Differential Gear OilNDS000ER
OIL LEAKAGE AND OIL LEVEL

Make sure that oil is not leaking from final drive assembly or around it.

Remove filler plug (1) and check oil level from filler plug mount-
ing hole as shown in the figure.
CAUTION:
Do not start engine while checking oil level.

Set a gasket on filler plug (1) and install it on final drive assem-
bly. Refer to FFD-15, "
COMPONENTS" .
CAUTION:
Do not reuse gasket.

lation.

When installing breather hoses (1) and tube (2), refer to the fig-
ure.
CAUTION:

ASSEMBLY INSPECTION AND ADJUSTMENT

Before inspection and adjustment, drain gear oil.
Total Preload Torque
1. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
2. Rotate drive pinion at least 20 times to check for smooth opera-
tion of the bearing.
3. Measure total preload with preload gauge.
NOTE:
Total preload torque = Pinion bearing preload torque + Side
bearing preload torque

If measured value is out of the specification, disassemble it to
check and adjust each part. Adjust the pinion bearing preload and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.
