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.

Refer to

DLN-323, "General Specification"

2. If the runout exceeds specifications, disconnect the propeller shaft at the final drive companion flange;

then rotate the companion 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 the vehicle.

• Inspect the propeller shaft runout. If runout exceeds the limit,

replace the propeller shaft assembly. Refer to

DLN-323, "General

Specification"

• While holding the flange yoke on one side, check axial play of the

joint as shown. If the journal axial play exceeds the specification,

repair or replace the journal parts. Refer to

DLN-323, "General

Specification"

• Check the propeller shaft tube surface for dents or cracks. If dam-

age 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

DLN-338, "NVH Troubleshooting Chart"

CAUTION:

Do not reuse the bolts and nuts. Always install new ones.

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

DLN-323

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. Refer to

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000007357586

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 SR 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 performed by

an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag

Module, see the SR 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 har-

ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a

hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing

serious injury.

• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000007357587

NOTE:

• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

″

LOCK

″

position.

• Always use CONSULT 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 NATS, an electrically controlled steering lock mech-

anism 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.
