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)

ALTERNATOR PULLEY INSPECTION
Perform the following.

Make sure that alternator pulley does not rattle.

Make sure that alternator pulley nut is tight.
INSTALLATION
Installation is the reverse order of removal.

Install alternator, and check tension of belt. Refer to EM-15, "Checking Drive Belts" .
CAUTION:
Be sure to tighten “B” terminal nut carefully.
