FRONT PROPELLER SHAFT
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
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 snap rings that will provide the specified play in an axial
direction of the journal, and install them. Refer toPR-12, "
Snap
Ring".
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.

APPEARANCE AND NOISE INSPECTION
lCheck the propeller shaft tube surface for dents or cracks. If damaged, replace the propeller shaft assem-
bly.
lCheck 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.
For measuring point, refer toPR-7, "
Propeller Shaft Runout
Measuring Point".
2. If the runout exceeds specifications, 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 runout still exceeds specifications, replace the propeller shaft assembly.
4. After installation, check for vibration by driving vehicle.

REMOVAL
1. Move the A/T select lever to the N position or set M/T shift lever to neutral position.
2. Release the parking brake.
3. Put matching marks on the rear propeller shaft flange yoke and
the rear final drive companion flange as shown.
CAUTION:
For matching marks, use paint. Never damage the rear pro-
peller shaft flange yoke or the companion flange.
4. Remove the bolts and nuts, then remove the propeller shaft from
the rear final drive and A/T, M/T or transfer.
INSPECTION
lInspect the propeller shaft runout. If runout exceeds the limit, replace the propeller shaft assembly.
For measuring point, refer toPR-7, "
Propeller Shaft Runout Measuring Point".
lWhile 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.
lCheck the propeller shaft tube for dents or cracks. If damage is
detected, replace the propeller shaft assembly.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EGS001M0
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
lTo 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.
lImproper 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.
lDo 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 SystemEGS001L9
lIn case of removing steering gear assembly, make the final tightening with grounded and unloaded vehi-
cle condition, and then check wheel alignment.
lObserve the following precautions when disassembling.
–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.
–Do not reuse non-reusable parts.
–Before assembling, apply the specified grease to the directed parts.
