APPEARANCE AND NOISE INSPECTION
Check the propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.
PROPELLER SHAFT VIBRATION
If vibration is present at high speed, inspect propeller shaft runout first.
1. Measure propeller shaft runout at runout measuring point by
rotating final drive companion flange with hands. For measuring
point, refer to PR-4, "
Propeller Shaft Runout Measuring Point" .
2. If runout still exceeds specifications, separate propeller shaft at
final drive companion flange; then rotate companion flange 90,
180, 270 degrees and install propeller shaft.
3. Check runout again. If runout still exceeds specifications,
replace propeller shaft assembly.
4. Check the vibration by driving vehicle.

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,

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.
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 Necessary for Steering Wheel Rotation After Battery DisconnectNGS000D0
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.

INSTALLATION OF UPPER JOINT, COLLAR, HOLE COVER SEAL, HOLE COVER, LOWER
SHAFT AND LOWER JOINT
Installation is the reverse order of removal. For tightening torque, refer to PS-13, "COMPONENTS" .
When installing upper joint, the angle which upper joint yoke (1)
forms with shaft center groove (A) should be at 90°.
When installing lower joint to steering gear assembly, follow the
procedure listed below.
–Set rack of steering gear in the neutral position.
NOTE:
To get the neutral position of rack, turn gear-sub assembly and
measure the distance of inner socket, and then measure the
intermediate position of the distance.
