APPEARANCE AND NOISE INSPECTION
 Check the propeller shaft tube surface for dents or crac ks. 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.
2. If the runout exceeds specif ications, 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 r unout still exceeds specifications,
replace the propeller shaft assembly.
4. After installation, check for vibration by driving vehicle. Limit

 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.
 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-194, "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-196, "Removal and Installation"
.
CAUTION:
Do not reuse the bolts and nuts. Always install new ones.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005875034
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 Wh eel Rotation After Battery Disconnect
INFOID:0000000005875035
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 disconnecti ng 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 pow er 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.

< PRECAUTION >[FRONT FINAL DRIVE: M205]
PRECAUTIONS
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 a ll control units using CONSULT-III.
Precaution for Servicing Front Final DriveINFOID:0000000004193536
 Before starting diagnosis of the vehicle, understand the symptoms well. Perform correct and systematic
operations.
 Check for the correct installation status prior to re moval or disassembly. When matching marks are required,
be certain they do not interfere with the f unction 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 dam age, 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 severa l 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.
