Revision: 2007 April2007 M35/M45
ASSEMBLY INSPECTION AND ADJUSTMENT

Before inspection and adjustment, drain gear oil.
Total Preload Torque
1. Secure final drive assembly onto an attachment.
2. Remove side flanges.
3. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
4. Rotate drive pinion at least 20 times to check for smooth opera-
tion of the bearing.
5. Measure total preload with the preload gauge.
NOTE:
Total preload torque = Pinion bearing preload torque + Side
bearing preload torque

If measured value is out of the specification, disassemble it to
check and adjust each part. Adjust the pinion bearing preload and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.
Drive Gear Runout
1. Remove rear cover. Refer to RFD-22, "Differential Assembly" .
2. Fit a dial indicator to the drive gear back face.
3. Rotate the drive gear to measure runout.

If the runout is outside of the repair limit, check drive gear
assembly condition; foreign material may be caught between
drive gear and differential case, or differential case or drive gear
may be deformed, etc.
CAUTION:
Replace drive gear and drive pinion gear as a set.Tool number A: KV38100800 (J-25604-01)
Tool number A: ST3127S000 (J-25765-A)
Total preload torque:
2.84 - 3.75 N·m (0.29 - 0.38 kg-m, 26 - 33 in-lb)
PDIA0766J
When the preload torque is large
On pinion bearings: Replace the collapsible spacer.
On side bearings: Use thinner side bearing adjusting washers by the same amount to
each side. Refer to RFD-38, "
Side Bearing Adjusting Washer" .
When the preload is small
On pinion bearings: Tighten the drive pinion lock nut.
On side bearings: Use thicker side bearing adjusting washers by the same amount to
each side. Refer to RFD-38, "
Side Bearing Adjusting Washer" .
Runout limit: 0.05 mm (0.0020 in)

On-Vehicle Inspection NES000J6
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION SUSPENSION ARM BALL JOINT AXIAL END PLAY
Measure axial end play by placing and moving up/down with an iron pry bar or something similar between sus-
pension arm and axle assembly.
CAUTION:
Be careful not to damage ball joint boot.
SHOCK ABSORBER INSPECTION
Check shock absorber for oil leakage, damage and replace if malfunction is detected.
Wheel Alignment InspectionNES000J7
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats in designated positions.
PRELIMINARY INSPECTION
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-6, "
ROAD WHEEL" .
3. Wheel bearing axial end play. Refer to RAX-5, "
WHEEL BEARING INSPECTION" .
4. Ball joint axial end play of suspension arm. Refer to RSU-5, "
INSPECTION SUSPENSION ARM BALL
JOINT AXIAL END PLAY" .
5. Shock absorber operation.
6. Each mounting point of axle and suspension for looseness and deformation.
7. Each of front lower link, rear lower link, radius rod, rear suspension member, suspension arm and shock
absorber for cracks, deformation, and other damage.
8. Vehicle height (posture).
GENERAL INFORMATION AND RECOMMENDATIONS

A four-wheel thrust alignment should be performed.
–This type of alignment is recommended for any NISSAN/INFINITI vehicle.
–The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel is
centered.
–The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle.
–The rack should be checked to ensure that it is level.

Make sure the machine is properly calibrated.
–Your alignment equipment should be regularly calibrated in order to give correct information.
–Check with the manufacturer of your specific equipment for their recommended Service/Calibration
Schedule.Standard value

PRE-CRASH SEAT BELT
Revision: 2007 April2007 M35/M45
FUNCTION DESCRIPTION
Operation condition
Pre-crash seat belt operates under the following conditions.
Operation prohibition condition
If operation condition is satisfied, pre-crash seat belt does not operate under the following conditions.
*1 : When pre-crash seat belt doesn't operate after it continuously operates 3 times or more, operation can be performed again by stop-
ping operation for approximately 7 minutes.
*
2 : Refer to SB-4, "FAIL-SAFE MODE" for details of fail-safe mode.
FAIL-SAFE MODE
When a malfunction occurs in the following system, the pre-crash seat belt function is controlled according to
the malfunctioning parts.
Also, seat belt warning lamp blinks with fastening driver seat belt when the following malfunction occurs.
Seat Belt Warning Lamp Illumination Pattern
NOTE:
The seat belt warning lamp illumination system shown above operates only when the air bag system does not
turn on the seat belt warning lamp. The air bag system turns on the seat belt warning lamp, depending on the
conditions of passenger being on and the passenger seat belt fastening.
Condition
When the brake pedal is depressed more than a certain extent

When operation prohibition condition is not satisfied
Condition

When seat belt is not fastened (Only the seat belt that is not fastened does not operate.)

When vehicle is moving backwards

When the vehicle speed is 15 km/h (9 MPH) or less

When pre-crash seat belt continuously operates 3 times or more *1

At fail-safe condition *2
Malfunctioning parts Control contents
