On-Vehicle Inspection
ADS000E7
PROPELLER SHAFT VIBRATION
If vibration is present at high speed, inspect propeller shaft runout first.
1.
Measure propeller shaft runout at several points by rotating final
drive companion flange with hands.
2.
If runout still exceeds specifications, disconnect propeller shaft
at final drive companion flange; then rotate companion flange
90, 180, 270 degrees and reconnect propeller shaft.
3.
Check runout again. If runout still exceeds specifications,
replace propeller shaft assembly.
4.
Perform driving test to check.
APPEARANCE AND NOISE INSPECTION
●
Inspect propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.
●
If center bearing is noisy or damage, replace propeller shaft assembly.
Removal and Installation
ADS000E8
REMOVAL
1.
Put mating marks onto propeller shaft flange yoke and final drive and transfer companion flanges.
CAUTION:
Use paint to avoid scratching the surface.
2.
Loosen mounting nuts of center bearing mount brackets with power tool.
CAUTION:
Tighten nuts temporarily.
3.
Remove mounting nuts and bolts from propeller shaft companion flanges, transfer, and final drive.
4.
Remove mounting nuts securing center bearing brackets onto vehicle. Then remove propeller shaft from-
vehicle.
CAUTION:
If constant velocity joint was bent during propeller shaft assembly removal, installation, or trans-
portation, its boot may be damaged. Wrap boot interference area to metal part with shop cloth or
rubber to protect boot from breakage.
Runout limit
: 0.6 mm (0.024 in) or less

INSPECTION AFTER REMOVAL
1.
As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace propeller shaft
assembly.
2.
Check propeller shaft for bend and damage. If damage is
detected, replace propeller shaft assembly.
3.
Check center bearing for noise and damage. If noise or damage
is detected, replace propeller shaft assembly.
CAUTION:
●
Center bearings cannot be disassembled.
●
Joints cannot be disassembled.
Axial play repair limit
: 0 mm (0 in)

INSTALLATION
Paying attention to following items, install in the reverse order of removal.
●
Align mating marks to install propeller shaft, and tighten to specified torque.
●
Adjust location of mounting bracket back and forth to prevent
longitudinal give of insulator as shown. Install bracket to vehicle.
●
After assembly, perform a driving test to check propeller shaft for
runout. If a runout is detected, separate propeller shaft from final
drive. Reinstall companion flange after rotating it by 90
°
, 180
°
,
and 270
°
. Then perform driving test and check propeller shaft
runout again at each point.

PRECAUTIONS
Revision; 2004 April

PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AGS000FW
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 for Steering System
AGS000CD
●
Before disassembly, thoroughly clean the outside of the unit.
●
Disassembly should be done in a clean work area. It is important to prevent the internal parts from becom-
ing contaminated by dirt or other foreign matter.
●
For easier and proper assembly, place disassembled parts in order on a parts rack.
●
Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere
with their operation.
●
Before inspection or reassembly, carefully clean all parts with a general purpose, non-flammable solvent.
●
Before assembly, apply a coat of recommended Genuine NISSAN PSF II or equivalent to hydraulic parts.
Petroleum jelly may be applied to O-rings and seals. Do not use any grease.
●
Replace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during installation.
Perform functional tests whenever designated.
