• 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 w hen installing. Since new caulking nuts are pre-oiled,
tighten as they are.

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)

How to Handle BatteryINFOID:0000000001328243
CAUTION:
 If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.
 After connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging
a battery.
 The battery surface (particularly its top) should always be kept clean and dry.
 The terminal connections should be clean and tight.
 At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as “low maintenance” and
“maintenance-free”.
 When the vehicle is not going to be used over a long period of time, disconnect the battery cable from the negative terminal.
 Check the charge condition of the battery. Periodically check the specific gr avity of the electrolyte. Keep a
close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, never touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush wit h water for 15 minutes and seek medical attention.

DIAGNOSTIC PROCEDURE 1
Check “B” Terminal Circuit
CAUTION:
Perform diagnosis under the cond ition that engine cannot start by the following procedure.
*1 For battery testing, use Battery Ser-
vice Center (J-480 87). For details
and operating instructions, refer to
Technical Service Bulletin and/or Bat-
tery Service Center User Guide. *2 Refer to "MINIMUM SPECIFICA-
TION OF CRANKING VOLTAGE
REFERENCING COOLANT TEM-
PERATURE". *3 Refer to "Check “B” Terminal Circuit".
*4 Refer to "Check “S” Connector Cir-
cuit".
