PRECAUTIONS
Revision: 2006 December 2006 FX35/FX45
PRECAUTIONSPFP:00001
CautionsNES000G0

When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on level ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.

Unladen conditions means that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.

After servicing suspension parts, be sure to check wheel alignment.

Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre-
oiled, tighten as they are.

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)

DIAGNOSTIC PROCEDURE 1
Check “B” Terminal Circuit
1. CHECK POWER SUPPLY FOR STARTER MOTOR “B” TERMINAL
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
3. Turn ignition switch OFF.
4. Make sure that the starter motor “B” terminal E313 terminal 2 connection is clean and tight.
5. Check voltage between starter motor “B” terminal E313 terminal 2 and ground.
OK or NG
OK >> GO TO 2.
NG >> Check harness between battery and starter motor for open circuit.
2. CHECK BATTERY CABLE CONNECTION (VOLTAGE DROP TEST)
Check voltage between starter motor “B” terminal E313 terminal 2
and battery positive terminal.
OK or NG
OK >> GO TO 3.
NG >> Check harness between battery and starter motor for poor continuity.
3. CHECK STARTER MOTOR GROUND CIRCUIT (VOLTAGE DROP TEST)
1. Turn ignition switch OFF.
2. Check voltage between starter motor case and battery negative terminal.
OK or NG
OK >> “B” terminal circuit is OK. Further inspection necessary. Refer to SC-11, "
Trouble Diagnosis with Starting/Charg-
ing System Tester (Starting)" .
NG >> Check starter motor case and ground for poor continuity.
*1 For battery testing, use Battery Ser-
vice Center (J-48087). For details
