INSPECTION
●
Inspect the propeller shaft runout. If runout exceeds the limit,
replace the propeller shaft assembly.
●
While holding the flange yoke on one side, check axial play of
the joint as shown. If the journal axial play exceeds the specifi-
cation, 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
PR-3, "NVH Troubleshooting Chart"
.
CAUTION:
Do not reuse the bolts and nuts. Always install new ones.

DISASSEMBLY
Journal
1.
Put matching marks on the rear propeller shaft and flange yoke
as shown.
CAUTION:
For matching marks use paint. Never damage the rear pro-
peller shaft or flange yoke.
2.
Remove the snap rings.
3.
Push out and remove the journal bearings by lightly tapping the
flange yoke with a hammer, taking care not to damage the jour-
nal or flange yoke hole.
NOTE:
Put marks on the disassembled parts so that they can be rein-
stalled in their original positions from which they were removed.
4.
Push out and remove the remaining journal bearings at the
opposite side by lightly tapping the flange yoke with a hammer,
taking care not to damage the journal or flange yoke hole.
NOTE:
Put marks on the disassembled parts so that they can be rein-
stalled in their original positions from which they were removed.

ASSEMBLY
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.

PRECAUTIONS

PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EGS00118
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
EGS00119
●
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 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.
