INSPECTION AFTER REMOVAL
Visual Inspection
Check the following:
Upper link and bushing for deformation, cracks or damage. Replace it if a malfunction is detected.
Ball joint boot for cracks or other damage, and also for grease leakage. Replace it if a malfunction is
detected.
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE:
Before measurement, move ball stud at least ten times by hand to check for smooth movement.
Hook a spring balance at cutout on ball stud. Confirm spring bal-
ance measurement value is within specifications when ball stud
begins moving.
If it is outside the specified range, replace upper link assembly.
Rotating Torque Inspection
Attach mounting nut to ball stud. Make sure that rotating torque
is within specifications with a preload gauge [SST].
If it is outside the specified range, replace upper link assembly.
Axial End Play Inspection
Move tip of ball stud in axial direction to check for looseness.
If it is outside the specified range, replace upper link assembly.
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to FSU-8, "Components" .
Perform final tightening of bolts and nuts at the vehicle installation position (rubber bushing) under
unladen conditions with tires on level ground. Check wheel alignment. Refer to FSU-6, "
Wheel Alignment
Inspection" . Swing torque

FRONT SUSPENSION ASSEMBLYPFP:54010
On-Vehicle Inspection and ServiceNES000IQ
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 InspectionNES000IR
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-31, "
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
Schedule.Axial end play : 0 mm (0 in)

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) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) 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
required.
