STEERING COLUMN
Revision: November 20092006 QX56
CAUTION:

When installing the steering column, finger-tighten all of the lower bracket and joint retaining
bolts; then tighten them to specification. Do not apply undue stress to the steering column.

The lower nut on the upper joint may not be reused.
NOTE:
Align slit of the coupling joint with projection on dust cover. Insert the
joint until surface "A" contacts surface "B".

After installation, turn steering wheel to make sure it moves
smoothly. Make sure the number of turns are the same from the
straight-forward position to left and right locks. Make sure that
the steering wheel is in a neutral position when driving straight
ahead.

When installing steering column to steering member, install
mounting nut from front side of vehicle.
INSPECTION AFTER INSTALLATION

After installing steering column to vehicle, check tilt device operation range is within specification.

Check if steering wheel operation can turn to the end of the left
and right stops smoothly.

4. Remove the cotter pin, then remove the nut from the drive shaft
using power tool.

Discard the cotter pin, use a new one for installation.
5. Remove the drive shaft. Refer to RAX-7, "
Removal and Installa-
tion" .
6. Remove the four wheel hub and bearing assembly bolts using power tool.

Discard the four wheel hub and bearing assembly bolts, use new ones for installation.
7. Pull out the wheel hub and bearing assembly for access to remove the rear ABS sensor from the wheel hub and bearing
assembly as shown.

Inspect the ABS sensor O-ring, replace the ABS sensor
assembly if damaged.

Clean the ABS sensor hole and mounting surface with a suit-
able brake cleaner and a clean lint-free shop rag. Be careful
that dirt and debris do not enter the axle bearing area.

Apply a coat of suitable grease to the ABS sensor O-ring and
mounting hole.
CAUTION:
Do not pull on the ABS harness.
8. Remove the wheel hub and bearing assembly.
INSTALLATION
Installation is in the reverse order of removal.

Apply grease 44003 7S000 to contact surface between wheel
hub and drive shaft. Use sufficient grease to completely coat
contact area.

Inspect the ABS sensor O-ring, replace the ABS sensor assem-
bly if damaged.

Clean the ABS sensor hole and mounting surface with a suitable
brake cleaner and a clean lint-free shop rag. Be careful that dirt
and debris do not enter the axle bearing area.

Apply a coat of suitable grease to the ABS sensor O-ring and
mounting hole.

Use a new cotter pin for installation.

Use new wheel hub and bearing assembly bolts for installation.

REAR DRIVE SHAFT
Revision: November 20092006 QX56
5. Separate the drive shaft from the wheel hub and bearing assembly by lightly tapping the end with a suit-
able hammer and wood block. If it is difficult to separate, use a suitable puller.
6. Remove the drive shaft. CAUTION:
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.
INSTALLATION
Installation is in the reverse order of removal.

Do not reuse the drive shaft inside flange bolts, discard after removal and use new bolts for installation.

Do not reuse the cotter pin, discard after removal and use a new cotter pin for installation.

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.
