REAR FINAL DRIVE ASSEMBLY
Revision: November 20092006 QX56
ASSEMBLY INSPECTION AND ADJUSTMENT

Drain the differential gear oil before inspection and adjustment. Refer to RFD-8, "DIFFERENTIAL GEAR
OIL" .

Remove and install the carrier cover as necessary for inspection and adjustment. Refer to RFD-12, "CAR-
RIER COVER" .
Total Preload Torque
1. Remove the side flanges if necessary. Refer to RFD-19, "Side Flange" .
CAUTION:
The side flanges shaft must removed in order to measure total preload torque.
2. Rotate the drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
3. Rotate the drive pinion at least 20 times to check for smooth operation of the bearings.
4. Measure the total preload torque using Tool.
NOTE:
Total preload torque = Drive pinion bearing preload torque +
Side bearing preload torque

If the measured value is out of the specification, check and adjust each part. Adjust the drive pinion
bearing preload torque first, then adjust the side bearing preload torque.
CAUTION:
Select a side bearing adjusting washer for right and left individually.

If the total preload torque is greater than specificationOn drive pinion bearings: Replace the collapsible spacer.
On side bearings: Use thinner side bearing adjusting washers by the same amount on each side. Refer to RFD-33, "
Side Bearing Adjusting
Washer" .
If the total preload torque is less than specification On drive pinion bearings: Tighten the drive pinion lock nut.
On side bearings: Use thicker side bearing adjusting washers by the same amount on each side. Refer to RFD-33, "
Side Bearing Adjust-
ing Washer" .

REAR SUSPENSION ASSEMBLY
Revision: November 20092006 QX56
Wheel Alignment InspectionEES001HH
Rear Wheel Alignment Adjusting Bolts
PRELIMINARY INSPECTION
WARNING:
Always adjust the alignment with the vehicle on a flat surface. Use CONSULT-II “EXHAUST SOLE-
NOID” active test to release the air pressure from the rear load leveling air suspension system.
NOTE:
If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before
making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for runout and damage. Refer to WT-5, "
Inspection" .
4. Check the wheel bearing axial end play.
5. Check the shock absorbers. Refer to RSU-27, "
SHOCK ABSORBER INSPECTION" .
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the rear suspension member for any damage.
8. Check the vehicle height. Refer to RSU-49, "
Wheelarch Height (Unladen*1 )" .

If vehicle height is not within ± 10 mm (0.39 in) of the specification, perform the control unit initialization
procedure. Refer to RSU-47, "
Initialization Procedure" .
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed.

This type of alignment is recommended for any NISSAN vehicle.

The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel
is centered.

The alignment machine itself should be capable of accepting any NISSAN vehicle.

The alignment machine should be checked to ensure that it is level.
2. Make sure the alignment machine is properly calibrated.

Your alignment machine should be regularly calibrated in order to give correct information.
