CautionNES000I6

When installing rubber bushings, the final tightening must be carried out under unladen conditions with
tires on ground. Oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
–Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.

After servicing suspension parts, be sure to check wheel alignment.

Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-
oiled, tighten as they are.

FRONT SUSPENSION ASSEMBLY
Revision: 2007 April2007 M35/M45
FRONT SUSPENSION ASSEMBLYPFP:54010
On-Vehicle Inspection NES000IA
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION OF UPPER LINK 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. Do not damage the installation position by applying
excessive force.
SHOCK ABSORBER INSPECTION
Check for oil leakage, damage and breakage of installation positions.
Wheel Alignment InspectionNES000IB
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 tires for improper air pressure and wear.

Check road wheels for runout. Refer to WT-6, "ROAD WHEEL" .

Check wheel bearing axial end play. Refer to FAX-5, "WHEEL BEARING INSPECTION" .

Check transverse link ball joint axial end play. Refer to FSU-14, "INSPECTION AFTER REMOVAL" .

Check shock absorber operation.

Check each mounting part of axle and suspension for looseness and deformation.

Check each of suspension member, shock absorber, upper link and transverse link for cracks, deforma-
tion and other damage.

Check 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.Axial end play : 0 mm (0 in)

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 the CCK gauge attachment [SST: KV991040S0 ( – )] with the following procedure on wheel, then
measure wheel alignment.
1. Remove three wheel nuts, and install the guide bolts to hub bolt.
2. Screw the adapter into the plate until it contacts the plate tightly.
3. Screw the center plate into the plate.
4. Insert the plate assembly on the guide bolt. Put the spring in,
and then evenly screw the three guide bolt nuts. When fastening
the guide nuts, do not completely compress the spring.
5. Place the dent of alignment gauge onto the projection of the
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. Replace suspect parts if a malfunction is
detected.

Kingpin inclination angle is reference value, no inspec-
tion is required.
