APPEARANCE AND NOISE INSPECTION
• Check the propeller shaft tube surface for dents or cracks. If damaged, replace the propeller shaft assembly.
• Check the bearings for noise and damage. Repair or replace the bearings as necessary.
PROPELLER SHAFT VIBRATION
If a vibration is present at high speed, inspect the propeller shaft runout first.
1. Measure the runout of the propeller shaft tube at several points
by rotating the final drive companion flange with your hands.
DLN-343, "General Specification"
.
2. If the runout exceeds specifications, disconnect the propeller
shaft at the final drive companion flange; then rotate the com-
panion flange 90
°
, 180
°
and 270
°
and reconnect the propeller
shaft.
3. Check the runout again. If the runout still exceeds specifications,
replace the propeller shaft assembly.
4. After installation, check for vibration by driving vehicle.

• Inspect the propeller shaft runout. If runout exceeds the limit,
replace the propeller shaft assembly. Refer to
• While holding the flange yoke on one side, check axial play of the
joint as shown. If the journal axial play exceeds the specification,
repair or replace the journal parts. Refer to
• Check the propeller shaft tube for dents or cracks. If damage is
detected, replace the propeller shaft assembly.
INSTALLATION
Installation is in the reverse order of removal.
• After installation, check for vibration by driving the vehicle. Refer to
DLN-337, "NVH Troubleshooting Chart"
.
• If propeller shaft assembly of final drive assembly has been
replaced, connect them as follows:
- Face companion flange mark (A) of the final drive (1) upward. With
the mark (A) faced upward, couple the propeller shaft and the final
drive so that the matching mark (B) of the propeller shaft (2) can be
positioned as close as possible with the matching mark (C) of the
final drive companion flange.
- Tighten propeller shaft and final drive bolts and nuts of the to spec-
ification. Refer to
DLN-339, "Removal and Installation"
CAUTION:
Do not reuse the bolts and nuts. Always install new ones.

Journal
1. Assemble the journal bearings. Apply multipurpose grease on
the bearing inner surface.
NOTE:
During assembly, use caution so that the needle bearings do not
fall down.
2. Select new snap rings that will provide the specified play in an
axial direction of the journal, and install them. Refer to
.
CAUTION:
Do not reuse snap rings
NOTE:
Select snap rings with a difference in thickness at both sides
within 0.02 mm (0.0008 in).
3. Adjust the thrust clearance between the bearing and snap ring
to zero by tapping the yoke.
4. Make sure that the journal moves smoothly and is below the
joint flex effort specification. Refer to
.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006245170
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 SR 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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR 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 har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
Precaution Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000006245171
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• 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 NATS, an electrically controlled steering lock mech-
anism 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.

6. Perform a self-diagnosis check of all control units using CONSULT-III.
Precaution for Servicing Front Final Drive
INFOID:0000000006245172
• Before starting diagnosis of the vehicle, understand the symptoms well. Perform correct and systematic
operations.
• Check for the correct installation status prior to removal or disassembly. When matching marks are required,
be certain they do not interfere with the function of the parts they are applied to.
• Overhaul should be done in a clean work area, a dust proof area is recommended.
• Before disassembly, completely remove sand and mud from the exterior of the unit, preventing them from
entering into the unit during disassembly or assembly.
• Always use shop paper for cleaning the inside of components.
• Avoid using cotton gloves or a shop cloth to prevent the entering of lint.
• Check appearance of the disassembled parts for damage, deformation, and abnormal wear. Replace them
with new ones if necessary.
• Gaskets, seals and O-rings should be replaced any time the unit is disassembled.
• Clean and flush the parts sufficiently and blow them dry.
• Be careful not to damage sliding surfaces and mating surfaces.
• When applying sealant, remove the old sealant from the mating surface; then remove any moisture, oil, and
foreign materials from the application and mating surfaces.
• In principle, tighten nuts or bolts gradually in several steps working diagonally from inside to outside. If a
tightening sequence is specified, observe it.
• During assembly, observe the specified tightening torque.
• Add new differential gear oil, petroleum jelly, or multi-purpose grease, as specified.
