Confirm there is no interference with vehicle.
13. Remove fuel filler tube protector and fuel filler tube, if necessary.
INSTALLATION
Note the following, and install in the reverse order of removal.

Surely clamp fuel hoses and insert hose to the length below.

Be sure hose clamp is not placed on swelled area of fuel tube.

Tighten fuel hose clamp so that the distance between its lugs becomes to the following.

To connect quick connector, refer to FL-7, "Quick Connector" .
INSPECTION AFTER INSTALLATION
Use the following procedure to check for fuel leaks.
1. Turn ignition switch “ON” (with engine stopped), and check connections for leakage by applying fuel pres- sure to fuel piping.
2. Start engine and rev it up and make sure there are no fuel leaks at the fuel system tube and hose connec- tions.

After removing/installing rear suspension assembly, make sure to adjust wheel alignment and then, adjust
neutral position of steering angle sensor. Refer to RSU-5, "
Wheel Alignment Inspection" and BRC-6,
"Adjustment of Steering Angle Sensor Neutral Position" .

FRONT SUSPENSION ASSEMBLY
Revision: 2006 December 2006 FX35/FX45
FRONT SUSPENSION ASSEMBLYPFP:54010
On-Vehicle Inspection and ServiceNES000I3
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION 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.
STRUT INSPECTION

Check strut for oil leakage, damage and replace if there are. Refer to FSU-11, "COIL SPRING AND
STRUT" .
Wheel Alignment InspectionNES000I4
DESCRIPTION

Measure wheel alignment under unladen conditions.
NOTE:
Unladen conditions mean that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are designated positions.
PRELIMINARY CHECK

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 compression rod, upper link, and steering knuckle

Check shock absorber operation.

Check each mounting part of axle and suspension for looseness and deformation.

Check each link, rod 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. Axial end play : 0 mm (0 in)
