Inspection and Adjustment
INFOID:0000000009267399
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
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 replace 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 recommended for any NISSAN 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 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 Sched-
ule.
Preliminary Check
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to
3. Wheel bearing axial end play. Refer to
4. Transverse link ball joint axial end play. Refer to
FSU-12, "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 specifications listed in this Service Manual.
• When displaying the alignment settings, many 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.

- 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 installing 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're using for more information.
ADJUSTMENT
Camber, Caster and Kingpin Inclination Angles
CAUTION:
Camber, caster, kingpin inclination angles cannot be adjusted.
