REAR SUSPENSION ASSEMBLY
On-Vehicle Inspection and ServiceINFOID:0000000001327552
Make sure the mounting conditions (looseness, ba ck 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 AlignmentInspectionINFOID:0000000001327553
DESCRIPTION
 Measure wheel alignment under unladen conditions. “U nladen conditions” means that fuel, engine coolant,
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 recomm ended for any NISSAN/INFINITI vehicle.
- The four-wheel “thrust” process helps ensure that t he 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 ca librated in order to give correct information.
- Check with the manufacturer of your specific equi pment for their recommended Service/Calibration Sched-
ule.
THE ALIGNMENT PROCESS
IMPORTANT:
Use only the alignment specificati ons listed in this Service Manual.
 When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
- The alignment specifications programmed into your machine that operate these indicators may not be cor-
rect.
- This may result in an ERROR.
 Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). DO NOT use this “Rolling Compensation”
method. Standard value
Axial end play : 0 mm (0 in)
