FRONT FOG LAMP
Revision: August 20072004 QX56
Aiming AdjustmentEKS007BF
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.

2. Measure the inner diameter of oil pump body to brazed portion
(position 6) using suitable tool.
3. Calculate the clearance using the following formula.

(Clearance) = (Inner diameter of oil pump body) - (Outer diameter of inner rotor)
Regulator Valve Clearance
Check regulator valve to oil pump cover clearance as follows:

(Clearance) = D1 (Valve hole diameter) - D2 (Outer Diameter
of valve)
CAUTION:

Coat regulator valve with engine oil.

Check that it falls smoothly into the regulator valve hole
by its own weight.
ASSEMBLY
Installation is in the reverse order of removal.
NOTE:
Install the inner rotor and outer rotor with the punched marks on the
oil pump cover side.

Balancing WheelsELS0010O
REMOVAL
1. Using a releasing agent, remove the double-faced adhesive taped wheel weight(s) from the wheel.
CAUTION:

Be careful not to scratch the wheel during removal.

After removing double-faced adhesive taped wheel weights, wipe clean any traces of the releas-
ing agent from the wheel.
WHEEL BALANCE ADJUSTMENT
NOTE:
If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting, select
and adjust a drive-in weight mode suitable for wheels.
1. Set the wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.
2. When the inner and outer imbalance values are shown on the wheel balancer indicator, multiply the outer
imbalance value by 1.6 to determine balance weight that should be used. Select the outer balance weight
with a value closest to the calculated value and install it to the designated outer position of, or at the des-
ignated angle in relation to the road wheel.
CAUTION:

Do not install the inner balance weight before installing the outer balance weight.

Before installing the balance weight, be sure to clean the mating surface of the wheel.Oil capacity and grade : Refer to RFD-11, "

Indicated imbalance value × 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance
weight (closer to calculated balance weight value)
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 g = 35 g (1.23 oz)
37.5 g = 40 g (1.41 oz)
a. Install balance weight in the position shown.
b. When installing balance weight to wheels, set it into the grooved
area on the inner wall of the wheel as shown so that the balance
weight center is aligned with the wheel balancer indication posi-
tion (angle).
CAUTION:

Always use Genuine NISSAN adhesion balance weights.

Balance weights are not reusable; always replace with
new ones.

Do not install more than three sheets of balance weights.
c. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other as shown.
CAUTION:
Do not install one balance weight sheet on top of another.
3. Start wheel balancer again.
4. Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start wheel balancer. Make sure that inner and outer residual
imbalance values are 5 g (0.18 oz) each or below.

If either residual imbalance value exceeds 5 g (0.18 oz), repeat installation procedures.

Service NoticeEDS0017L
1. Before proceeding with disassembly, thoroughly clean the outside of the all-mode 4WD transfer. It is
important to prevent the internal parts from becoming contaminated by dirt or other foreign matter.
2. Disassembly should be done in a clean work area.
3. Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the all-mode 4WD transfer.
4. Place disassembled parts in order for easier and proper assembly.
5. All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
6. Gaskets, seals and O-rings should be replaced any time the all-mode 4WD transfer is disassembled.
7. It is very important to perform functional tests whenever they are indicated.
8. The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place removed parts in a parts rack in order to replace them in correct positions and sequences. Care will
also prevent springs and small parts from becoming scattered or lost.
9. Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
10. Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, and to hold bearings and washers in place during assembly. Do not use grease.
11. Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
12. After overhaul, refill the transfer with new ATF.
13. When the all-mode 4WD transfer drain plug is removed, only some of the fluid is drained. Old all-mode
4WD transfer fluid will remain in torque converter and ATF cooling system. Always follow the proper pro-
cedure. Refer to MA-24, "
Changing Transfer Fluid" .
Wiring Diagrams and Trouble DiagnosisEDS001CE
When you read wiring diagrams, refer to the following:

GI-15, "How to Read Wiring Diagrams" .

PG-4, "POWER SUPPLY ROUTING CIRCUIT" for power distribution circuit.
When you perform trouble diagnosis, refer to the following:

GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES".

CAUTION:

Be careful not to scratch the wheel during removal.

After removing double-faced adhesive tape, wipe clean traces of releasing agent from the

WHEEL BALANCE ADJUSTMENT

If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for wheels.
1. Set wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.
2. When inner and outer imbalance values are shown on the wheel balancer indicator, multiply outer imbal-
ance value by 1.6 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value and install it to the designated outer position of, or at the desig-
nated angle in relation to the road wheel.
CAUTION:

Do not install the inner balance weight before installing the outer balance weight.

Before installing the balance weight, be sure to clean the mating surface of the wheel.
