REAR SUSPENSION ASSEMBLY
Inspection and Adjustment
WARNING:
If the vehicle is equipped with the ICC cruise control system and the rear toe has been adjusted during a wheel alignment, the millimeter wave sensor must be adjusted. Refer to "Millimeter Wave Sensor Adjustment" Millimeter Wave Sensor Adjustment.
Before checking the rear wheel alignment, make a preliminary inspection.
- Measure the wheel alignment under unladen conditions.
NOTE:
Unladen conditions mean that fuel, engine coolant, and lubricants are full and that the spare tire, jack, hand tools and mats are in their designated positions.
PRELIMINARY INSPECTION
- Check the tires for wear and for improper inflation.
- Check the wheels for deformation, cracks, and other damage. Remove the wheel and check the wheel runout. Refer to "Adjustment" Service and Repair.
- Check the rear wheel bearings for looseness.
- Check the rear suspension for looseness.
- Check that the rear shock absorbers work properly.
- Check the wheel arch height in the unladen condition. Refer to "Wheel Arch Height" Wheel Arch Height.
GENERAL INFORMATION AND RECOMMENDATIONS
1.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 machine itself should be capable 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 alignment machine for their recommended Service/Calibration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to "Wheel Arch Height" Wheel Arch Height.
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.
2.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 Compensation" 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.

CAMBER
- Measure the camber of both the right and left wheels using a suitable alignment gauge and adjust using the following procedure.
- If the camber is not within specification, adjust the camber by turning the adjusting bolts in the same direction.
1.Turn the adjusting bolts in the same direction to calibrate.
NOTE:
Camber changes about 0� 5 (0.08�) with each graduation of the adjusting bolt.
2.Tighten the adjusting bolt nuts to the specified torque.
TOE-IN
- Measure the toe-in of the rear wheels. If out of specification, inspect and replace any damaged or worn rear suspension parts before adjusting.
- Adjust toe-in by turning adjusting bolt on rear lower link.
NOTE:
Toe changes about 1.5 mm (0.059 in) [one side] with each graduation of the adjusting bolt.
- After adjusting, tighten the adjusting bolt nut to the specified torque.
