ADJUSTMENT AND SELECTION OF ADJUSTING WASHERS
Differential Side Gear Clearance

Assemble the differential parts if they are disassembled. Refer to FFD-17, "Differential Assembly" .
1. Place differential case straight up so that side gear to be mea-
sured comes upward.
2. Using feeler gauge, measure the clearance between side gear
back and differential case at 3 different points, while rotating
side gear. Average the 3 readings, and then measure the clear-
ance of the other side as well.
CAUTION:
To prevent side gear from tilting, insert feeler gauges with
the same thickness from both sides.
3. If the back clearance is outside the specification, use a thicker/
thinner side gear thrust washer to adjust. Refer to FFD-23, "
Dif-
ferential Side Gear Clearance" .
CAUTION:
Select a side gear thrust washer for right and left individually.
Pinion Gear Height

Drive gear and pinions are supplied in matched sets only.Match-
ing numbers on both pinion and drive gear are etched for verifi-
cation. If a new gear set is being used, verify the numbers of
each pinion gear and drive gear before proceeding with assem-
bly.

The mounting distance from the centerline of the drive gear to the back face of the pinion gear for the
M205 final drive is 103.5 mm (4.0748 inches).
On the button end of each pinion, there is etched a plus (+) number, a minus (-) number, or a zero (0),
which indicates the best running position for each particular gear set. This dimension is controlled by a
selective shim between the inner pinion bearing race and pinion gear.
For example: If a pinion is etched m+8 (+3), it would require 0.08 mm (0.003 inch) less shim than a pinion
etched “0”. This means decreasing shim thickness; increases the mounting distance of the pinion to 103.6
mm (4.0778 inches). If a pinion is etched m+8 (-3), it would require adding 0.08mm (0.003 inch) more to
the shim than would be required if the pinion were etched “0”. By adding 0.08 mm (0.003 inch), the mount-

When the back clearance is large:
Use a thicker thrust washer.
When the back clearance is small:

ON-VEHICLE SERVICEPFP:00000
Front Suspension PartsEES001GI
Check front suspension parts for excessive play, cracks, wear and
other damage.

Shake each front wheel to check for excessive play.
If looseness is noted, inspect wheel bearing end play, then
check ball joint end play. Refer to FAX-5, "
WHEEL BEARING
INSPECTION" and FSU-15, "Inspection" .

Make sure that the cotter pin is inserted (4x4 only).

Retighten all nuts and bolts to the specified torque.

Check shock absorber for oil leakage and other damage.

Check suspension ball joint for grease leakage and ball joint
dust cover for cracks and other damage.
Front Wheel AlignmentEES001GJ
PRELIMINARY INSPECTION
WAR NIN G:
Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, inspect and replace any damaged or worn 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 run out and damage. Refer to WT-5, "
Inspection" .
4. Check the wheel bearing axial end play. Refer to FAX-5, "
WHEEL BEARING INSPECTION" .
5. Check the shock absorbers for leaks or damage.
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 FSU-21, "
Wheelarch Height (Unladen*1 )" .

Verify the level using Consult-II memory register 1103 and set to 0 ± 10 mm (0 ± 0.39 in) as necessary.
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.Suspension component torques : Refer to FSU-5,

FRONT FOG LAMP
Revision: October 20052005 QX56
Aiming AdjustmentEKS00B9M
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.

Keep all tires inflated to correct pressure.

Place vehicle on level ground.

See that vehicle is unloaded (except for full levels of coolant,
engine oil and fuel, and spare tire, jack, and tools). Have the
driver or equivalent weight placed in driver seat.
Adjust aiming in the vertical direction by turning the adjustment
screw.
NOTE:
Access adjustment screw from underneath front bumper. Turn screw
clockwise to raise pattern and counterclockwise to lower pattern.
1. Set the distance between the screen and the center of the fog
lamp lens as shown.
2. Turn front fog lamps ON.
3. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is 200 mm (7.9 in) below the height of
the fog lamp centers as shown.

When performing adjustment, if necessary, cover the headlamps
and opposite fog lamp.

GAP ADJUSTMENT
NOTE:
If any gap or height difference between glass lid and roof panel is found, check glass lid fit and adjust as fol-
lows:
1. Open sunshade assembly.
2. Loosen glass lid securing screws (2 each on left and right sides), then tilt glass lid down.
3. Manually adjust glass lid from outside of vehicle so it resembles "A-A" as shown in the figure.
4. After adjusting glass lid tilt glass lid up and tighten screws.
5. Tilt glass lid up and down several times to check that it moves smoothly.
HEIGHT DIFFERENCE ADJUSTMENT
1. Remove headlining. Refer to EI-38, "HEADLINING" .
2. Loosen sunroof frame assembly nuts and sunroof bracket bolts.
3. Add shims until gap is within specification "A-A" as shown.
NOTE:
Temporarily snug nuts and bolts to prevent movement between each adjustment.
4. Tilt glass lid assembly up and down several times to check that it moves and seals properly.
5. Tighten sunroof frame assembly nuts and sunroof bracket bolts.
NOTE:
First tighten left front then right rear sunroof frame assembly nuts to prevent uneven torque while tighten-
ing sunroof bracket bolts.
6. Install headlining. Refer to EI-38, "
HEADLINING" .
Removal and InstallationEIS008ZM

After any adjustment, check sunroof operation and glass lid alignment.

Handle glass lid with care so not to cause damage.

For easier installation, mark each point before removal.
