On-Vehicle Inspection and Service
NES00065
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION LOWER BALL JOINT END PLAY
1.
Set front wheels in a straight-ahead position. Do not depress brake pedal.
2.
Place an iron bar or similar tool between transverse link and steering knuckle.
3.
Measure axial end play by prying it up and down.
CAUTION:
Be careful not to damage ball joint boot.
STRUT INSPECTION
●
Check strut for oil leakage, damage and replace if there are. Refer to
Wheel Alignment Inspection
NES000HL
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.

THE 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 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). DO NOT use this “Rolling Compensation”
method.
–
Use the “Jacking Compensation Method”. After installing the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
–
See Instructions in the alignment machine you're using for more information on this.
INSPECTION OF CAMBER, CASTER AND KINGPIN INCLINATION ANGLES
●
Camber, caster, kingpin inclination angles cannot be adjusted.
●
Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so vehicle will remain horizontal.
Using a CCK Gauge
Install CCK gauge attachment [SST: KV991040S0 ( – )] as following procedure in wheel, then measure
wheel alignment.
1.
Remove wheel nuts (2), and install a guide bolts to hub bolts.
2.
Screw adapter into plate body until it contacts plate tightly.
3.
Screw center plate into plate.
4.
Insert plate on guide bolts. Put spring in, and then evenly screw
both guide bolt nuts. When fastening guide nuts, do not com-
pletely compress springs.
5.
Place the dent of alignment gauge onto the projection of center
plate and tightly contact them to measure.
CAUTION:
●
If camber, caster, or kingpin inclination angle is outside
the standard, check front suspension parts for wear and
damage, and replace suspect parts if necessary.
●
King pin inclination angle is reference value, no inspection is required. (Due to the type of sus-
pension, the kingpin inclination angle cannot be measured correctly using a normal alignment
tester.)
