b.

Adjust position of the bearing cushion so as not to apply thrust
play to the center bearing insulator.

c.

Position the bearing cushion overlap as shown in the figure.

d.

Install the center bearing bracket (upper) with its arrow mark fac-
ing forward.

e.

Tighten the center bearing mounting bracket (upper) fixing nuts
to specified torque.

CAUTION:

Do not reuse the nuts. Always replace the nuts with a new
one. 

2.

If companion flange has been removed, put new alignment
matching mark B on it. Then, reassemble using the following
procedure.
Perform these steps when either of final drive and shaft is
replaced with a new one. 

a.

Erase original mark B from companion flange with suitable sol-
vent.

b.

Measure companion flange vertical runout.

c.

Determine the position where maximum runout is read on dial
indicator. Put mark (shown by B in figure) on flange perimeter
corresponding to maximum runout position.

3.

If the propeller shaft or final drive has been replaced, connect
the propeller shaft and final drive as follows:

NOTE:
Avoid damaging the rebro joint boot, protect it with a shop towel
or equivalent.

●

Install the propeller shaft while aligning its matching mark A
with the mark C on the joint as close as possible.

●

Tighten the joint bolts/nuts to specified torque.

CAUTION:

Do not reuse the bolts, and washers. Always replace
them with new ones.

●

After installation, check the vibration by driving the vehicle. If the vibration is present, remove the pro-
peller shaft from the final drive companion flange.

●

Turn the propeller shaft 60, 120, 180, 240 or 300 degrees and reinstall the propeller shaft to the com-
panion flange, then measure the runout again by driving the vehicle on each angle position.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT 
BELT PRE-TENSIONER”

AGS000D2

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

AGS000BU

●

Be careful with the following items while at overhaul.

–

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.

–

Place disassembled parts in order, on a parts rack, for easier and proper assembly.

–

Use nylon cloths 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.
Vaseline 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.

–

Wash disassembled parts (except rubber parts) with kerosene, dry them by air blowing and paper towels.

●

Mark places that fluid is leaked by a white marker to repair.

●

Overhaul the oil pump, check damage (scratches, too) for cover assembly, side plates, shaft kit, rotor
vanes and flow control valve, replace new one with each part if necessary.
