5. Loosen mounting nuts of center bearing mounting brackets.
CAUTION:
Tighten mounting nuts temporarily.
6. Remove propeller shaft fixing bolts and nuts.
7. Remove center bearing mounting bracket fixing nuts.
8. Remove propeller shaft.
CAUTION:
If constant velocity joint was bent during propeller shaft
assembly removal, installation, or transportation, its boot
may be damaged. Wrap boot interference area to metal part
with shop cloth or rubber to protect boot from breakage.
INSPECTION
Inspect propeller shaft runout at measuring points. If runout
exceeds specifications, replace propeller shaft assembly. For
measuring point, refer to PR-6, "
Propeller Shaft Runout Measur-
ing Point" .
As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace relevant propeller
shaft.
Check propeller shaft for bend and damage. If damage is
detected, replace relevant propeller shaft assembly.
CAUTION:
Do not disassemble joints.
Check center bearing for noise and damage. If noise or damage
is detected, replace center bearing. Refer to PR-11, "
Disassem-
bly and Assembly of Center Bearing (For 3S80A-1VL107 and
3F80A-1VL107 Type)" .

INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Avoid damaging the rebro joint boot, protect it with a shop towel or equivalent.
Align matching marks to install propeller shaft to final drive and transfer (AWD models only) companion
flanges, and then tighten to specified torque. Refer to PR-7, "
Components" .
Install center bearing mounting bracket (Upper) with its arrow
mark facing forward.
Adjust position of mounting bracket sliding back and forth to pre-
vent play in thrust direction of center bearing insulator. Install
bracket to vehicle.
After assembly, perform a driving test to check propeller shaft
vibration. If vibration occurred, separate propeller shaft from
final drive. Reinstall companion flange after rotating it by 60,
120, 180, 240, 300 degrees. Then perform driving test and
check propeller shaft vibration again at each point.
If propeller shaft or final drive has been replaced, connect them
as follows:
1. Install the propeller shaft while aligning its matching mark A with
the matching mark B on the joint as close as possible.
2. Tighten the joint bolts to the specified torque. Refer to PR-7,
"Components" .
CAUTION:
Do not reuse the bolts, nuts and washers.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NGS000CZ
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.
WAR NING :
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 Necessary for Steering Wheel Rotation after Battery DisconnectNGS000D0
NOTE:
Before removing and installing any control units, first turn the push-button ignition switch to the LOCK
position, then disconnect both battery cables.
After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, 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. Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-II.
