DESCRIPTION

Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Jack, hand tools and mats are in designated positions.
 
 PRELIMINARY CHECK

Check the following:
  • Tires for improper pressure and wear.
  • Wheel bearing axial end play. Refer to Inspection.
  • Ball joint axial end play of suspension arm. Refer to Inspection (GT-R certified NISSAN dealer).
  • Shock absorber operation.
  • Each mounting point of axle and suspension for looseness and deformation.
  • Each of front lower link, rear lower link, radius rod, rear suspension member, suspension arm and shock absorber for cracks, deformation, and other damage.
  • Vehicle height (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.
 
 ALIGNMENT PROCESS

IMPORTANT:
Use only the alignment specifications 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 correct.
    • This may result in an ERROR.
  • See instructions in the alignment machine.
