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)

INSPECTION AFTER REMOVAL
Visual Inspection
Check suspension arm and bushing for deformation, cracks, or damage. If any non-standard condition is
found, replace it.
Check boot of ball joint for cracks, or damage, and also for grease leakage.
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE:
Before measuring, move ball joint at least ten times by hand to check for smooth movement.
Hook a spring balance at cotter pin mounting hole. Confirm
spring balance measurement value is within the specifications
when ball stud begins moving.
If it is outside the specified range, replace suspension arm
assembly.
Rotating Torque Inspection
Attach mounting nut to ball stud. Make sure rotating torque is
within the specifications with a preload gauge (SST).
If it is outside the specified range, replace suspension arm
assembly.
Axial End Play Inspection
Move tip of ball joint in axial direction to check for looseness.
If it is outside the specified range, replace suspension arm assembly. Swing torque:
0.5 − 3.4 N·m (0.06 − 0.34 kg-m, 5 − 30 in-lb)
Measured value of spring scale:
9.7 − 66.0 N (0.99 − 6.7 kg, 2.18 − 14.8 lb)
