ENGINE MAINTENANCE (VK45DE ENGINE)PFP:10001
Checking Drive BeltsNLS0006C
WARNING:
Be sure to perform when the engine is stopped.
Remove air duct (inlet) when inspecting drive belt for alternator, water pump and A/C compressor.
Remove front engine undercover with power tool when inspecting power steering oil pump belt.
Make sure that indicator (single line notch) of each auto tensioner is within the allowable working range
(between three line notches).
NOTE:
Check auto tensioner indication when engine is cold.
When new drive belt is installed, the range should be “A”.
The indicator notch is located on the moving side of the tensioner for alternator, water pump and A/C
compressor belt, while it is found on the fixed side for power steering oil pump belt.
Visually check entire belt for wear, damage or cracks.
If the indicator is out of allowable working range or belt is damaged, replace belt.
Tension AdjustmentNLS0006D
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.
Changing Engine CoolantNLS0006E
WARNING:
To avoid being scalded, do not change engine coolant when engine is hot.
Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressure. Then turn radiator cap all the way.
Be careful not to allow engine coolant to contact drive belts.

Tire RotationNLS0006U
After rotation the tires, adjust the tire pressure.
Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tire, etc.).
CAUTION:
Do not include the T-type spare tire when rotating the tires.
When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
Be careful not to tighten wheel nut at torque exceeding the
criteria for preventing strain of disc rotor.
Checking Brake Fluid Level and LeaksNLS0006V
If fluid level is extremely low, check brake system for leaks.
Checking Brake Lines and CablesNLS0006W
Check brake fluid lines and parking brake cables for improper
attachment, leaks, chafing, abrasions, deterioration, etc.
Changing Brake FluidNLS0006X
1. Drain brake fluid from each bleed valve.
2. Refill until new brake fluid comes out from each bleed valve. Use same procedure as in bleeding hydraulic system to refill
brake fluid.
Refer to BR-10, "
Bleeding Brake System" .
Refill with recommended Genuine Nissan Super Heavy Duty
Brake Fluid or equivalent DOT 3 (US FMVSS No. 116).
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
Never reuse drained brake fluid.
Be careful not to splash brake fluid on painted areas. Tightening torque of wheel nut
: 108 N·m (11 kg, 83 ft-lb)

STEERING WHEEL
Revision: 2006 July 2007 FX35/FX45
STEERING WHEELPFP:48430
On-Vehicle Inspection and ServiceNGS000BW
CHECKING CONDITION OF INSTALLATION
Check installation condition of steering gear assembly, front suspension, axle and steering column.
Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
Check if the mounting bolts for steering gear assembly are loose
or not. Refer to PS-18, "
POWER STEERING GEAR AND LINK-
AGE" .
CHECKING STEERING WHEEL PLAY
1. Set tires to the straight ahead, start engine, then turn steering wheel to the left and right lightly, and mea-
sure steering wheel movement on the outer circumference when steering wheel is turned up to the point
where tires start moving.
CHECKING NEUTRAL POSITION ON STEERING WHEEL
Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-
6, "Wheel Alignment Inspection" .
1. Set vehicle to the straight direction, check if steering wheel is in the neutral position.
2. If it is not in the neutral position, remove steering wheel and reinstall it correctly.
3. If the neutral position cannot adjust in the two teeth of steering gear assembly, loosen outer socket lock nuts of steering outer sockets, then adjust outer socket by the same amount in the opposite direction.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating temperature. [Make sure temperature of fluid is approximately 50 to 80 °C (122 to 176 °F).]
NOTE:
Tires need to be inflated normal pressure.
4. Check steering wheel turning force when steering wheel has been turned 360 ° from neutral position.
NOTE:
Multiply the distance L from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
5. If steering wheel turning force is out of the specification, check rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer to PS-30,
"On-Vehicle Inspection and Service" .
a. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to PS-13, "
COMPO-
NENTS" , FAX-4, "COMPONENTS" , FA X - 1 0 , "COMPONENTS" .

REAR SUSPENSION ASSEMBLYPFP:55020
On-Vehicle Inspection and ServiceNES000HU
Make sure the mounting conditions (looseness, back lash) of each component and component status (wear,
damage) are normal.
INSPECTION OF BALL JOINT END PLAY
Measure axial end play by installing and moving up/down with an
iron pry bar or something similar between suspension arm and axle.
CAUTION:
Be careful not to damage ball joint boot.
SHOCK ABSORBER INSPECTION
Check shock absorber for oil leakage, damage and replace if necessary.
Wheel Alignment InspectionNES000HV
DESCRIPTION
Measure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, engine cool-
ant, and lubricant are full. Spare tire, jack, hand tools and mats in designated positions.
PRELIMINARY INSPECTION
Check tires for improper air pressure and wear.
Check road wheels for runout.
Check wheel bearing axial end play.
Check ball joint axial end play of suspension arm.
Check shock absorber operation.
Check each mounting point of axle and suspension for looseness and deformation.
Check each link, arm and member for cracks, deformation, and other damage.
Check vehicle posture.
GENERAL INFORMATION AND RECOMMENDATIONS
A four-wheel thrust alignment should be performed.
–This type of alignment is recommended for any NISSAN/INFINITI vehicle.
–The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel is
centered.
–The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle.
–The rack should be checked to ensure that it is level.
Make sure the machine is properly calibrated.
–Your alignment equipment should be regularly calibrated in order to give correct information.
–Check with the manufacturer of your specific equipment for their recommended Service/Calibration
Schedule. Standard value
Axial end play : 0 mm (0 in)

3. SYMPTOM CHECK
Check again.
OK or NG
OK >> INSPECTION END
NG >> Replace electric controlled coupling for mechanical malfunction (mechanical engagement of
clutch is not possible.). Refer to TF-45, "
Disassembly and Assembly" .
While Driving, AWD Warning Lamp Flashes Rapidly (When Flashing in Approx.
1 Minute and Then Turning OFF)
NDS000AH
NOTE:
Rapid flashing: 2 times/second
This symptom protects drivetrain parts when a heavy load is applied to the electric controlled coupling and
multiple disc clutch temperature increases. Also, optional distribution of torque sometimes becomes rigid
before lamp flashes rapidly. Both cases are not malfunction.
When this symptom occurs, stop vehicle and allow it to idle for some times. Flashing will stop and system will
be restored.
While Driving, AWD Warning Lamp Flashes Slowly (When Continuing to Flash
until Turning Ignition Switch OFF)
NDS000AI
NOTE:
Slow flashing: 1 time/2 seconds
DIAGNOSTIC PROCEDURE
1. CHECK TIRE
Check the following.
Tire pressure
Wear condition
Longitudinal tire size (There is no difference between longitudinal tires.)
OK or NG
OK >> GO TO 2.
NG >> Drive at vehicle speed of 20 km/h (12 MPH) or more for 5 seconds or more after repairing or
replacing damaged parts. (Initialize improper size tire information.)
2. CHECK INPUT SIGNAL OF TIRE DIAMETER
With CONSULT-II
1. Start engine.
2. Drive at 20 km/h (12 MPH) or more for approx. 200 seconds.
3. Select “DATA MONITOR” mode for “ALL MODE AWD/4WD” with CONSULT-II.
4. Check monitor “DIS-TIRE MONI”.
Display of
“DIS-TIRE MONI”
