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 calib rated in order to give correct information.
- Check with the manufacturer of your specific equi pment for their recommended Service/Calibration Sched-
ule.
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). Never 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). Never use this “Rolling Compensation” method.
- Use the “Jacking Compensation Method”. After installi ng the alignment targets or head units, raise the vehi-
cle and rotate the wheels 1/2 turn both ways.
- See Instructions in the alignment machine you're using for more information on this.
