 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.
