WHEEL ALIGNMENT
InspectionINFOID:0000000012430301
PRELIMINARY INSPECTION
WARNING:
Always adjust the wheel alignment with the vehicle on a flat surface.
NOTE:
If the wheel alignment is out of s pecification, inspect and replace any damaged or worn rear suspension parts
before making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, engine coolant, and lubricants are full; the spare tire, jack, hand tools and mats are in
designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for run out and damage. Refer to WT-54, "
Wheel".
4. Check the wheel bearing axial end play. Refer to FAX-27, "
Wheel Bearing".
5. Check the shock absorbers for leaks or damage.
6. Check each mount point of the suspension co mponents for any excessive looseness or damage.
7. Check each link, arm, and the suspension member for any damage.
8. Check the vehicle height. Refer to FSU-21, "
Wheelarch Height (Unladen*)".
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed.
• This type of alignment is recomm ended 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 machine itself should be capabl e of accepting any NISSAN/INFINITI vehicle.
• The alignment machine should be checked to ensure that it is level.
2. Make sure the alignment machine is properly calibrated. • Your alignment machine should be regularly calibrated in order to give correct information.
• Check with the manufacturer of your specific a lignment machine for their recommended Service/Cali-
bration Schedule.
ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to FSU-20, "Wheel
Alignment (Unladen*1)".
• 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 alignment machine that operate these indicators may
not be correct.
- This may result in an ERROR.
• Most camera-type alignment machines are equipped with "Rolling Compensation" method and optional
"Jacking Compensation" method to "compensate" the alignment targets or head units.
"Rolling Compensation" is the preferred method.
- If using the "Rolling Compensation" method, after inst alling the alignment targets or head units, push or pull
on the rear wheel to move the vehicle. Do not push or pull on 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 in either direction.
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.
CAMBER, CASTER AND KINGPIN INCLINATION ANGLES INSPECTION
• Camber, caster, kingpin inclination angles cannot be adjusted.
• Before inspection, set the front wheels onto a turning radius gauge. Set the rear wheels onto a pad that has
the same height so the vehicle will remain horizontal.
TOTAL TOE-IN INSPECTION
Measure the total toe-in using the following procedure.

WHEEL ALIGNMENT
WARNING:
• Always perform the following procedure on a flat surface.
• Make sure that no person is in fr ont of vehicle before pushing it.
1. Bounce the front of vehicle up and down to stabilize the vehicle height (posture).
2. Push on the rear wheel to move the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of each tire at the same height of hub center. These are measuring points.
4. Measure the distance (A) from the rear side.
5. Push on the rear wheel to move the vehicle slowly ahead and to rotate the wheels 180 degrees (1/2 turn).
CAUTION:
If the wheels have rotated more than 180 degrees (1/2 turn),
try the above procedure again from the beginning. Do not
push vehicle backward.
6. Measure the distance (B) from the front side.
7. Use the formula below to calculate total toe-in.
• If the total toe-in is outside the specification, adjust the total toe-in. Refer to FSU-8, "
Adjustment".
AdjustmentINFOID:0000000012430302
TOTAL TOE-IN
Loosen the steering outer socket. Adjust the length using the steering inner socket.
CAUTION:
• Always evenly adjust toe-in alternately and adjust the difference be tween the left and right to the
standard.
• Always hold the steering inner socket wh en tightening the steering outer socket.

2. Hook the Tool (A) on the ball joint (B). Confirm the measurement value is within specifications when the ball stud begins moving.
If swing torque or rotating torque exceeds the specified range,
replace transverse link.
Axial End Play
1. Move the ball stud at least ten times by hand to check for smooth movement with no binding.
2. Move the tip of the ball joint in the axial direction to check for looseness.
If the axial end play exceeds the specified range, replace transverse link.
INSPECTION AFTER INSTALLATION
1. Check wheel alignment. Refer to FSU-20, "Wheel Alignment (Unladen*1)".
2. Perform the steering angle sensor neutral position adjustment. Refer to BRC-55, "

SPIRAL CABLE
• Set the spiral cable neutral position by carefully turning the spiralcable (1) clockwise to the stop position. Turn the spiral cable coun-
terclockwise 2.5 turns stopping when the locating pin (A) is at the
top most position, triangles (B) are aligned as shown and the win-
dow (C) appears white.
NOTE:
If a new service part is installed, the neutral position is already set
with a stopper clip in place and should not be adjusted after the
stopper clip is removed. Make sure the stopper clip is removed
before installing the steering wheel.
• During steering wheel (2) installation, make sure the locating pin hole (D) is aligned with the locating pin (A) of the spiral cable.
• Adjust the neutral position of the steering angle sensor. Refer to
BRC-55, "
ADJUSTMENT OF STEERI NG ANGLE SENSOR NEU-
TRAL POSITION : Description".
CAUTION:
• The spiral cable may snap during steering operation if the spiral cable is installed in an improper
position.
• Do not overturn the spiral cable or go beyond the maximum number of turns allowed. This will cause
the cable to snap.
• Do not apply lubricant to the spiral cable.
• Do not allow oil, grease, detergent or water to come in contact with the spiral cable.
• After the work is completed, perform diagnosis to check that no malfunction is detected. Refer to
SRC-14, "
Description".
