WHEEL ALIGNMENT
InspectionINFOID:0000000006225640
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
Check the following:
Tires for improper air pressure and wear
Road wheels for runout: Refer to WT-64, "
Inspection".
Wheel bearing axial end play: Refer to FA X - 7 , "
Inspection" (2WD), FAX-16, "Inspection" (4WD).
Lower link and upper link ball joint axial end play: Refer to FSU-15, "
Inspection" and FSU-18, "Inspection".
Shock absorber operation.
Each mounting part of axle and suspension for looseness and deformation
Lower link 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 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.
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). 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.
