Wheel Alignment InspectionNES00006
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
Unladen conditions mean that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are designated positions.
PRELIMINARY CHECK
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 compression rod, upper link, and steering knuckle
Check shock absorber operation.
Check each mounting part of axle and suspension for looseness and deformation.
Check each link, rod 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 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.
