When removing the drive shaft, do not bend at an excessive angle to the drive shaft joint. Do not
excessively extend the slide joint.
INSPECTION AFTER REMOVAL

Move the joint up and down, left and right, and in the axial direc-
tion. Check for any rough movement or significant looseness.

Check the boot for cracks or other damage, and for any grease
leakage.

If necessary, disassemble the drive shaft, and repair as neces-
sary.

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.

To disconnect the hoses, push in on the lock ring using a suit-
able tool and pull the hose out.
5. Remove both of the rear wheel and tire assemblies using power tool.
6. Remove the brake caliper without disconnecting the brake hoses, using power tool. Reposition the brake caliper out of the
way using a suitable wire. Refer to BR-28, "
Removal and Instal-
lation of Brake Caliper and Disc Rotor" .
CAUTION:

Do not crimp or stretch the brake hose when repositioning the brake caliper out of the way.

Do not press brake pedal while the brake caliper is removed.
7. Remove the spare tire.
8. Disconnect the two rear ABS sensor electrical connectors.

12. Disconnect the parking brake cables from the brackets on the rear suspension member.
13. Set a suitable jack to support each of the rear lower links and the coil spring tension.
14. Remove both of the rear lower link outer bolts and lower the jack to remove the rear coil springs.
15. Remove the two bolts to disconnect the seat belt latch anchor from the rear suspension member.
16. Disconnect both of the connecting rods from the rear stabilizer bar.
17. Set a suitable jack under the rear suspension member.
18. Remove the six rear suspension member bolts.
19. Slowly lower the jack to remove the rear suspension member, suspension arm, front and rear lower links and stabilizer bar as
an assembly.
20. If necessary, remove the suspension arm, spare tire bracket, height sensor, rear load leveling air suspension hoses, stabilizer
bar, knuckle, and front and rear lower links from the rear suspension member.

REAR SUSPENSION MEMBER
Revision: November 20092006 QX56
INSTALLATION
Installation is in the reverse order of removal.

When raising the rear suspension member assembly, use the
locating pins to align the rear suspension member to the vehicle
body.

When installing the upper and lower rubber seats for the rear
coil springs, the arrow embossed on the rubber seats must point
out toward the wheel and tire assembly.

To connect the rear load leveling air suspension hoses, the lock
ring must be fully seated in the fitting. Insert the hose “B” into the
lock ring “A” until the lock ring “A” is touching the hose “B” as
shown. Pull on the hose to check that it is securely inserted.

Perform the final tightening of the nuts and bolts for the links (rubber bushing) under unladen condition
(unladen condition means that the fuel tank, engine coolant and lubricants are at the full specification, and
the spare tire, jack, hand tools, and mats are in their designated positions) with the tires on level ground.

Check the wheel alignment. Refer to RSU-48, "Wheel Alignment" .
