On-Vehicle Inspection

NDS00086

APPEARANCE AND NOISE INSPECTION

●

Check the propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.

●

If center bearing is noisy or 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 points by
rotating final drive companion flange with hands.

2.

If runout still exceeds specifications, separate propeller shaft at
final drive companion flange or transfer companion flange; then
rotate companion flange 90, 180, 270 degrees and install pro-
peller 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.

●

Align matching marks to install propeller shaft to final drive and transfer companion flanges, and then
tighten to specified torque. Refer to 

PR-5, "COMPONENTS"

 .

●

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 or transfer. Reinstall companion flange after rotating it
by 90, 180, 270 degrees. Then perform driving test and check
propeller shaft vibration again at each point.

●

If propeller shaft or final drive has been replaced, install them as follows;

1.

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

2.

Tighten fixing bolts and nuts to the specified torque. Refer to

PR-5, "COMPONENTS"

 .

PRECAUTIONS

Revision: 2006 July

2007 Murano

PRECAUTIONS

PFP:00001

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

NGS000FA

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 Disconnect

NGS000FB

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-II 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-II.

Precautions for Steering System

NGS0003B

●

In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehi-
cle condition, and then check wheel alignment.

●

Observe 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.
