INSPECTION AFTER REMOVAL
Check the following items, and replace the part if necessary.
• Check components for deformation, cracks, and other damage.
• Check boots of transverse link and steering outer so cket ball joint for breakage, axial end play, and swing
torque. Refer to FSU-10, "
Inspection" and FSU-20, "Ball Joint".
INSPECTION AFTER DISASSEMBLY
Wheel Hub
• Check wheel hub for cracks (with magnetic exploration or dye testing). Replace if necessary.
Steering Knuckle
• Check steering knuckle for deformation, cracks, and other damage. Replace if any non-standard conditions
are found.
Snap Rings
• Check snap ring for wear or cracks. Replace if necessary.
INSPECTION AFTER ASSEMBLY
Check wheel bearing rotating torque as per the following instructions.
NOTE:
The adequacy of turning torque can be judged from a measurement value by a spring balancer.
1. For a proper fit of the bearing, turn the wheel hub clockwise and counterclockwise, respectively, 10 times
or more with a press-fit load applied.
2. Set a suitable tool on strut mounting hole (upper). Measure rotating torque at an rpm of 8 - 12 rpm.
• If the turning torque cannot be obtained by the above method, measure the torque, according to the instructions below.
- Install drive shaft and tighten the hub lock nut to the specified
torque. Rotate the wheel hub to fit properly.
- Set a suitable tool on a wheel nut and measure turning torque at turning speeds of 8 to 12 rpm.
INSPECTION BEFORE INSTALLATION
Check wheel sensor rotor for foreign matter. Clean the rotor, if necessary.
INSPECTION AFTER INSTALLATION
1. Check wheel sensor harness to be sure the connectors are fully seated. Refer to BRC-140, "FRONT
WHEEL SENSOR : Removal and Installation".
2. Check the wheel alignment. Refer to FSU-7, "
Inspection".

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.

< PERIODIC MAINTENANCE >
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.
