DRIVE SHAFT
Revision: August 20072004 QX56
4. Attach the circlip to the drive shaft. The circlip must fit securely
into the drive shaft groove. Attach the nut to the joint sub-assem-
bly.
Use a soft hammer to press-fit the circlip.
NOTE:
Discard the old circlip and use a new one for assembly.
5. Insert the specified quantity of Genuine NISSAN Grease or
equivalent, into the joint sub-assembly and the large end of the
boot. Refer to MA-10, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
6. Install the boot securely into the grooves (indicated by the *
marks) as shown.
CAUTION:
If there is grease on the boot mounting surfaces (indicated
by the * marks) of the drive shaft and joint sub-assembly,
the boot may come off. Remove all grease from the drive
shaft surfaces.
7. Check that the boot installation length “L” is the specified length.
Insert a flat-tip screwdriver or similar tool into the big end of the
boot. Bleed the air from the boot to prevent boot deformation.
CAUTION:

The boot may break if the boot installation length is less than the specified length.

Do not contact inside surface of boot with the tip of the screwdriver.
8. Secure the big and small ends of the boot using new boot bands
as shown.
NOTE:
Discard the old boot bands and use new ones for assembly.
9. After installing the joint sub-assembly to the drive shaft, rotate the boot to check that it is positioned cor-
rectly. If the boot is not positioned correctly, reposition the boot and secure the boot using a new boot
band.Grease capacity : 145 − 165 g (5.11 − 5.82 oz)

ON-VEHICLE SERVICE
Revision: August 20072004 QX56
TOE-IN
WAR NIN G:

Always perform the following procedure on a flat surface.

Make sure that no person is in front of the vehicle before pushing it.
1. Bounce the front of vehicle up and down to stabilize the vehicle height (posture).
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both front tires
at the same height as hub center as shown. These marks are
measuring points.
4. Measure the distance “A” on the rear side of the front tires as
shown.
5. Push the vehicle slowly ahead to rotate the wheels 180°
degrees (1/2 a turn).
CAUTION:
If the wheels have rotated more than 180° degrees (1/2
turn), start this procedure again from the beginning. Never
push the vehicle backward.
6. Measure the distance “B” on the front side of the front tires at the
same marks as shown. Total toe-in is calculated as “A” – “B”.
7. Adjust the toe-in by varying the length of the steering outer tie-
rods.
a. Loosen the outer tie-rod lock nuts.
b. Adjust the toe-in by screwing the outer tie-rods in or out.
c. Tighten the outer tie-rod lock nuts to specification.
FRONT WHEEL TURNING ANGLE
1. Start engine and run at idle.
2. Set wheels in straight-ahead position. Then move vehicle for-
ward until front wheels rest on turning radius gauge properly.

Make sure vehicle is level.
3. Rotate steering wheel all the way right and left; measure turning
angle.

If front wheel turning angles are out of the specification, check
if the following parts are worn or damaged.

PRECAUTIONS
Revision: August 20072004 QX56
(i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect
the emission control devices and systems, and could also affect the warranty coverage validity.
Precautions for Multiport Fuel Injection System or Engine Control SystemEAS0014B

Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.

Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.

Be careful not to jar components such as ECM and mass air
flow sensor.
Precautions for HosesEAS0014C
HOSE REMOVAL AND INSTALLATION

To prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.

To reinstall the rubber hose securely, make sure of hose inser-
tion length and clamp orientation. (If tube is equipped with hose
stopper, insert rubber hose into tube until it butts up against
hose stopper.)
HOSE CLAMPING

If old rubber hose is re-used, install hose clamp in its original
position (at the indentation where the old clamp was). If there is
a trace of tube bulging left on the old rubber hose, align rubber
hose at that position.

Discard old clamps; replace with new ones.

HEADLAMP (FOR USA)
Revision: August 20072004 QX56

The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.

Light output is nearly double that of halogen headlamps, affording increased area of illumination.

The light features a high relative spectral distribution at wavelengths to which the human eye is most sen-
sitive. This means that even in the rain, more light is reflected back from the road surface toward the vehi-
cle, for added visibility.

Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, unless the combination switch (lighting
switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlamps
are turned off.
AUTO LIGHT OPERATION
Refer to LT- 4 8 , "System Description" for auto light operation.
VEHICLE SECURITY SYSTEM (PANIC ALARM)
The vehicle security system (panic alarm) will flash the high beams if the system is triggered. Refer to BL-48,
"Panic Alarm Operation" .
CAN Communication System DescriptionEKS0079R
Refer to LAN-5, "CAN COMMUNICATION" .

INSPECTION AFTER REMOVAL

Check for damage to steering column jacket tube. If damage is found, replace steering column with new
one.

If vehicle has been in a collision, check column length “L1” and
“L2” as shown. If out of specification, replace steering column
with new one.

Check for proper lubrication, apply grease as necessary.

ASSEMBLY

Assembly is in the reverse order of disassembly.

Install new tamper resistant self-shear screws.
INSPECTION AFTER ASSEMBLY
When the steering wheel does not turn smoothly, check the steering column as follows:
1. Check the column bearings for damage or unevenness. Lubricate with recommended multi-purpose
grease. Replace the steering column as an assembly, if necessary.
2. Check the column tube for deformation or breakage. Replace the steering column as an assembly, if nec-
essary.
3. If the vehicle has been involved in a collision, or if noise and rat-
tles are heard during a turn, check the length "L" of the column.
If out of specification, replace the steering column as an assem-
bly.
4. Check for proper lubrication, apply grease as necessary.
5. Check for wear around the seal edges, replace the steering col-
umn as an assembly as necessary.
6. Check for corrosion or pitting around the seal sliding area.
7. After installing the steering column, check the tilt mechanism for
proper operation.
CAUTION:

Replace the column if it is depleted of grease, worn, dam-
aged, or if any scratches or coating separation is present
on the shaft seal area.

During lower joint detachment, insert a tool into the yoke
groove to prevent gouging damage.
