STEERING COLUMN
• 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 mount-
ing 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.

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 necessary.
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.

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-30, "
Removal and Installation" .
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-44, "
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-42, "
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.

• 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 FSU-19, "
Wheel Alignment (Unladen*1) *6" .
