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,

HEADLAMP (FOR USA)
Revision: October 20052005 QX56
Aiming AdjustmentEKS00B89
For details, refer to the regulations in your state.
Before performing aiming adjustment, check the following.
1. Ensure all tires are inflated to correct pressure.
2. Place vehicle and screen on level surface.
3. Ensure there is no load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant and engine oil filled to correct level, and fuel tank full.
4. Confirm spare tire, jack and tools are properly stowed.
5. If equipped, confirm headlamp aiming switch is set to "0" (zero) position.
LOW BEAM AND HIGH BEAM
NOTE:
Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
1. Turn headlamp low beam on.
2. Use adjusting screw to perform aiming adjustment.

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.

OIL LEVEL

Before starting the engine make sure the vehicle is parked on a
flat and level surface, then check the oil level. If the engine is
already running, turn it off and allow 10 minutes before check-
ing.

Check that the oil level is within the low (L) and high (H) range
as indicated on the dipstick.

If the engine oil level is out of range, add oil as necessary. Refer
to GI-45, "
Recommended Chemical Products and Sealants" .
OIL APPEARANCE

Check the engine oil for a white milky appearance or excessive contamination.

If the engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken
parts.
OIL LEAKAGE
Check for oil leakage around the following areas:

Oil pan

Oil pan drain plug

Oil pressure sensor

Oil filter

Oil cooler

Intake valve timing control cover

Intake valve timing control solenoid valve

Front cover

Mating surface between cylinder block and cylinder head

Mating surface between cylinder head and rocker cover

Crankshaft oil seal (front and rear)
OIL PRESSURE CHECK
WA RN ING:

Be careful not to burn yourself, as engine oil may be hot.

Put the selector lever in the Park “P” position.
1. Check the engine oil level. Refer to LU-7, "
OIL LEVEL" .
2. Remove engine front undercover using power tool.
3. Disconnect the oil pressure sensor harness connector.
4. Remove the oil pressure sensor.

2005 QX56
INSTALLATION
Installation is in the reverse order of removal, paying attention to the following:

Confirm that no foreign objects are adhering to the sealing sur-
faces of the oil cooler or oil pan.

Tighten the connecting bolt after aligning the stopper on the oil
pan side with protrusion of the oil cooler.
INSPECTION AFTER INSTALLATION
1. Check levels and add engine oil and engine coolant. Refer to LU-7, "OIL LEVEL" and CO-10, "LEVEL
CHECK" .
2. Start the engine, and check for leaks of engine oil and engine coolant.
3. Stop engine and wait for 10 minutes.
4. Check engine oil level and engine coolant level again.
