FRONT SUSPENSION ASSEMBLY
Revision: 2006 January2006 M35/M45
FRONT SUSPENSION ASSEMBLYPFP:54010
On-Vehicle Inspection and ServiceNES000IA
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION OF 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. 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 the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-6, "
ROAD WHEEL" .
3. Wheel bearing axial end play. Refer to FAX-5, "
WHEEL BEARING INSPECTION" .
4. Transverse link ball joint axial end play. Refer to FSU-14, "
INSPECTION AFTER REMOVAL" .
5. Shock absorber operation.
6. Each mounting part of axle and suspension for looseness and deformation.
7. Each of suspension member, shock absorber, upper link and transverse link for cracks, deformation and
other damage.
8. 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.

COIL SPRING AND SHOCK ABSORBER
Revision: 2006 January2006 M35/M45
2. Using a spring compressor (commercial service tool), compress
coil spring between rubber seat and spring lower seat (on shock
absorber) until coil spring with a spring compressor is free.
CAUTION:
Be sure a spring compressor is securely attached coil
spring. Compress coil spring
3. Make sure coil spring with a spring compressor between rubber
seat and spring lower seat (shock absorber) is free and then
remove piston rod lock nut while securing the piston rod tip so
that piston rod does not turn.
4. Remove shock absorber mounting bracket, rubber seat, bound
bumper from shock absorber.
5. Remove coil spring with a spring compressor, and then gradually release a spring compressor.
CAUTION:
Loosen while making sure coil spring attachment position does not move.
6. Remove the strut attachment from shock absorber.
INSPECTION AFTER DISASSEMBLY
Shock Absorber Inspection
Check the following:
Shock absorber for deformation, cracks or damage, and replace it if a malfunction is detected.
Piston rod for damage, uneven wear or distortion, and replace it if a malfunction is detected.
For oil leakage, and replace it if a malfunction is detected.
Shock Absorber Mounting Bracket and Rubber Parts Inspection
Check shock absorber mounting bracket for cracks and rubber parts for wear. Replace it if a malfunction is
detected.
Coil Spring Inspection
Check coil spring for cracks, wear or damage, and replace it if a malfunction is detected.
ASSEMBLY
CAUTION:
Do not damage shock absorber piston rod when installing components to shock absorber.
1. Install strut attachment [SST] to shock absorber and secure it in
a vise.
CAUTION:
When installing the strut attachment to shock absorber,
wrap a shop cloth around strut to protect it from damage.
2. Compress coil spring using a spring compressor (commercial
service tool), and install it onto shock absorber.
