Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951705
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
General PrecautionsINFOID:0000000009460620
• When installing rubber bushings, the final tightening mu st 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.
Precaution for Procedure without Cowl Top CoverINFOID:0000000009460621
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.
Precautions for SuspensionINFOID:0000000009460622
• When installing rubber bushings, the final tightening mu st be carried out under unladen conditions with tires
on ground. Spilled 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.

FRONT SUSPENSION ASSEMBLY
Inspection and AdjustmentINFOID:0000000009460626
INSPECTION
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
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 upper link and steering knuckle.
3. Measure axial end play by prying it up and down.Refer to FSU-26, "Ball Joint"
.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
SHOCK ABSORBER
Check for oil leakage, damage and repl ace if malfunction is detected.
WHEEL ALIGNMENT
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.
General Information and Recommendations
• A four-wheel thrust alignment should be performed.
- This type of alignment is re commended for any NISSAN vehicle.
- The four-wheel "thrust" process helps ensure that t he vehicle is properly aligned and the steering wheel is
centered.
- The alignment rack itself should be capable of accepting any NISSAN 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 ca librated in order to give correct information.
- Check with the manufacturer of your specific equi pment for their recommended Service/Calibration Sched-
ule.
Preliminary Check
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-60, "Road Wheel"
.
3. Wheel bearing axial end play. Refer to FAX-27, "Wheel Bearing"
.
4. Transverse link ball joint axial end play. Refer to FSU-11, "Removal and Installation"
.
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).
Alignment Process
IMPORTANT:
Use only the alignment specificati ons listed in this Service Manual.
• When displaying the alignment settings, m any alignment machines use "indicators" Do not use these indi-
cators. : (Green/red, plus or minus, Go/No Go).
- The alignment specifications programmed into your machine that operate these indicators may not be cor-
rect.

FSU-8
< PERIODIC MAINTENANCE >
FRONT SUSPENSION ASSEMBLY
- This may result in an ERROR.
• Most camera-type alignment machines are equipped with both "Rolling Compensation" method and optional
"Jacking Compensation" method to "compensate" the alignment targets or head units. "Rolling Compensa-
tion" is the preferred method.
- If using the "Rolling Compensation" method, after installing the alignment targets or head units, push or pull on the rear wheel to move the vehicle. Do not push or pull the vehicle body.
- If using the "Jacking Compensation" method, after inst alling the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
NOTE:
Do not use the "Rolling Compensation" method if you are using sensor-type alignment equipment.
- Follow all instructions for the alignment machine you are using for more information.
ADJUSTMENT
Camber, Caster and Kingpin Inclination Angles
CAUTION:
Camber, caster, kingpin inclinat ion angles cannot be adjusted.

• Do not depress brake pedal while brake caliper is removed.
• Do not twist or stretch the brake hose.
3. Put alignment marks on disc rotor and rear wheel hub and bearing assembly, then remove disc rotor.
4. Remove wheel sensor and wheel sensor harness from strut. Refer to BRC-124, "Exploded View - Front
Wheel Sensor".
5. Remove the stabilizer connecting rod (1). Refer to FSU-14,
"Removal and Installation".

10. Remove the steering knuckle and hub.
11. Remove transverse link bolts (A) and the transverse link from suspension member.
INSPECTION AFTER REMOVAL
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
1. Move ball stud at least ten times by hand to check for smooth movement.
2. Hook a spring balance (A) at pinch bolt location. Confirm spring balance measurement value is within specifications when ball
stud begins moving.
- If swing torque exceeds standard range, replace transverse link.
Axial End Play Inspection
1. Move ball stud at least ten times by hand to check for smooth movement.
2. Move tip of ball stud in axial direction to check for looseness.
