7. Use a ball joint remover (SST) to remove steering outer socket
from steering knuckle. Be careful not to damage ball joint boot.
CAUTION:
To prevent damage to threads and to prevent ball joint
remover (SST) from coming off suddenly, temporarily
tighten mounting nut.
8. Using a puller (suitable tool), remove wheel hub and bearing assembly from drive shaft. NOTE:

When removing wheel hub and bearing assembly, do not apply an excessive angle to drive shaft joint.
Also be careful not to excessively extend slide joint.

Do not hang over drive shaft with out support.
9. Remove wheel hub and bearing assembly fixing bolt.
10. Remove splash guard and wheel hub and bearing assembly from steering knuckle.
11. Remove strut assembly and steering knuckle fixing bolts and nuts.
12. Remove transverse link and steering knuckle fixing bolt and nut.
13. Remove steering knuckle from vehicle.
INSPECTION AFTER REMOVAL
Check for deformity, cracks and damage on each parts, replace if necessary.
Ball Joint Inspection
Check for boot breakage, axial looseness, and torque of transverse link and steering outer socket ball joint.
Refer to FSU-14, "
TRANSVERSE LINK" , PS-18, "POWER STEERING GEAR AND LINKAGE" .
INSTALLATION
CAUTION:
Be sure to replace the new differential side oil seal every removal of drive shaft. Refer to FFD-11,
"SIDE OIL SEAL" .

Refer to FAX-10, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

To assemble disc rotor and wheel hub and bearing assembly,
align the marks.
(When not using the alignment mark, refer to BR-20, "
Removal
and Installation of Brake Caliper Assembly" .)

PRECAUTIONS
Revision: 2006 July 2007 FX35/FX45
PRECAUTIONSPFP:00001
CautionNES000FK

When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on ground. Oil will 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.

Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre-
oiled, tighten as they are.

Avoid burden to front cross bar.

FRONT SUSPENSION ASSEMBLYPFP:54010
On-Vehicle Inspection and ServiceNES000I3
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 FSU-11, "COIL SPRING AND
STRUT" .
Wheel Alignment InspectionNES000I4
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. 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 CCK gauge attachment [SST: KV991040S0 ( – )] as following procedure in wheel, then measure
wheel alignment.
1. Remove wheel nuts (3), 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.)

16. Remove stabilizer connecting rod upper nut with power tool,
separate stabilizer connecting rod and strut assembly.
17. Remove mounting nuts between engine mounting insulator and front suspension member.
18. Remove mounting bolts which are at the back of transverse link (mounting part with body) with power tool, separate transverse
link.
19. Remove mounting nuts between front suspension member and body with power tool.
20. Move jack down slowly to remove front suspension member, transverse link, stabilizer bar, drive shaft (For AWD models) and
steering knuckle from vehicle as a unit.
21. Remove transverse link from steering knuckle. Refer to FSU-14,
"TRANSVERSE LINK" .
INSTALLATION

Refer to FSU-8, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

After removing/installing or replacing suspension components and steering components, check wheel
alignment. Refer to FSU-6, "
Wheel Alignment Inspection" .

After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .

Check the following item after service.
–Installation condition of wheel sensor harness.
