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.

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

shock absorber from transverse link.
6. Remove cotter pin of transverse link and steering knuckle, and then loosen nut.
7. Remove transverse link from steering knuckle so as not to damage ball joint boot using the ball joint
remover (suitable tool).
CAUTION:
Temporarily tighten the nut to prevent damage to threads and to prevent ball joint remover (suit-
able tool) from suddenly coming off.
8. Remove the mounting nuts of shock absorber mounting bracket, then remove shock absorber from vehi-
cle.
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to FSU-8, "Components" .
Perform final tightening of bolt and nut at the shock absorber lower side (rubber bushing), under unladen
conditions with tires on level ground. Check wheel alignment. Refer to FSU-6, "
Wheel Alignment Inspec-
tion" .
Adjust neutral position of steering angle sensor after checking wheel alignment. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .
Check wheel sensor harness for proper connection. Refer to BRC-57, "WHEEL SENSOR" .

CAUTION:
Do not damage shock absorber piston rod when removing components from 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. 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.

Before measurement, move ball stud at least ten times by hand to check for smooth movement.
Hook a spring balance at cutout on ball stud. Confirm spring bal-
ance measurement value is within specifications when ball stud
begins moving.

Rotating Torque Inspection
Attach mounting nut to ball stud. Make sure that rotating torque
is within specifications with a preload gauge [SST].
If it is outside the specified range, replace upper link assembly.
