Always use the support point specified for lifting.
Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for
unavoidable reasons, support at the rear axle jacking point with transmission jack or similar tool
before starting work, in preparation for the backward shift of center of gravity.
For supporting points for lifting and jacking point at rear axle, refer to GI-42, "Garage Jack and
Safety Stand and 2-Pole Lift" .
REMOVAL
Outline
At first, remove engine, transmission assembly with front suspension member from vehicle downward. Then
separate engine from transmission.
Preparation
1. Release fuel pressure. Refer to EC-809, "FUEL PRESSURE RELEASE" .
2. Drain engine coolant from radiator. Refer to CO-40, "
Changing Engine Coolant" .
CAUTION:
Perform this step when engine is cold.
Do not spill engine coolant on drive belts.
3. Disconnect both battery cables. Refer to SC-4, "
BATTERY" .
4. Remove crankshaft position sensor (POS) from transmission.
CAUTION:
Handle carefully to avoid dropping and shocks.
Do not disassemble.
Do not allow metal powder to adhere to magnetic part at sensor tip.
Do not place sensors in a location where they are exposed to magnetism.
5. Remove the following parts:
Front and rear engine undercover (power tool)
Air duct (inlet), air duct and air cleaner case assembly; Refer to EM-177, "AIR CLEANER AND AIR
DUCT" .
Front road wheels and tires (power tool)
Engine Room LH
1. Disconnect heater hoses, and install plugs to avoid leakage of engine coolant.
2. Disconnect wire bonding from exhaust manifold cover to vehicle.
3. Disconnect vacuum hose between vehicle and engine and set it aside.
4. Discharge refrigerant from A/C circuit. Refer to ATC-151, "
REFRIGERANT LINES" .
5. Remove A/C piping from A/C compressor, and temporarily fasten it on vehicle with a rope. Refer to AT C -
151, "REFRIGERANT LINES" .
Engine Room RH
1. Disconnect fuel feed hose and EVAP hose. Refer to EM-193, "FUEL INJECTOR AND FUEL TUBE" .
CAUTION:
Fit plugs onto disconnected hose to prevent fuel leak.
2. Disconnect ground cable (between vehicle and right bank cylinder head).
3. Disconnect vacuum hose between vehicle and engine and set it aside.
4. Disconnect reservoir tank of power steering oil pump from engine, and move it aside for easier work.
CAUTION:
When temporarily securing, keep reservoir tank upright to avoid a fluid leak.
Ve h i c le i n s i d e
Follow procedure below to disconnect engine room harness connectors at passenger room side, and tempo-
rarily secure them on engine.
1. Remove passenger-side kicking plate, dash side finisher, and glove box. Refer to EI-37, "
BODY SIDE
TRIM" and IP-10, "INSTRUMENT PANEL ASSEMBLY" .
2. Disconnect engine room harness connectors at unit sides TCM, ECM and other.

FRONT SUSPENSION ASSEMBLY
Revision: 2006 January2006 M35/M45
FRONT SUSPENSION ASSEMBLYPFP:54010
On-Vehicle Inspection and ServiceNES000IA
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION OF LOWER BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Place an iron bar or similar tool between transverse link and steering knuckle.
3. Measure axial end play by prying it up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
SHOCK ABSORBER INSPECTION
Check for oil leakage, damage and breakage of installation positions.
Wheel Alignment InspectionNES000IB
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-6, "
ROAD WHEEL" .
3. Wheel bearing axial end play. Refer to FAX-5, "
WHEEL BEARING INSPECTION" .
4. Transverse link ball joint axial end play. Refer to FSU-14, "
INSPECTION AFTER REMOVAL" .
5. Shock absorber operation.
6. Each mounting part of axle and suspension for looseness and deformation.
7. Each of suspension member, shock absorber, upper link and transverse link for cracks, deformation and
other damage.
8. Vehicle height (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

PERIODIC MAINTENANCE
Revision: 2006 January2006 M35/M45
NOTE:
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) fluid (A/T, trans-
fer)/oil at every 30,000 miles (48,000 km) or 24 months. Using automatic transmission fluid other than Genuine NISSAN Matic J
ATF will cause deterioration in driveability and automatic transmission durability, and may damage the automatic transmis-
sion, which is not covered by the INFINITI new vehicle limited warranty.
(2) Refer to “Tire rotation” under the “GENERAL MAINTENANCE” heading earlier in this section.
Schedule 2NLS0007D
EMISSION CONTROL SYSTEM MAINTENANCE
Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary. [ ]: At the mileage intervals only
NOTE:
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found
damaged or if the auto belt tensioner reading (only for VK45DE engine) reaches the maximum limit.
(2) Maintenance-free item. For service procedures, refer to FL section.
(3) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(4) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are
