Wheel Alignment InspectionRear Wheel Alignment Adjusting Bolts:
PRELIMINARY INSPECTION
WARNING: Always adjust the alignment with the vehicle on a flat surface. Use CONSULT-III "EXHAUST SOLENOID" active test to release the air pressure from the rear load leveling air suspension system.
NOTE: If alignment is out of specification, 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, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in their designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for runout and damage.
4. Check the wheel bearing axial end play.
Axial end play: 0 mm (0 in)
5. Check the shock absorbers. Refer to RSU-8, "Inspection". Testing and Inspection
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the rear suspension member for any damage.
8. Check the vehicle height. Refer to "Wheelarch Height (Unladen*1)". [1][2]Ride Height (Unladen)
^ If vehicle height is not within ± 10 mm (0.39 in) of the specification, perform the control unit initialization procedure. Refer to SCS-7, "CONSULT-III Function". Scan Tool Testing and Procedures
GENERAL INFORMATION AND RECOMMENDATIONS
1. 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 machine itself should be capable of accepting any NISSAN 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 RSU-28, "Wheel Alignment (Unladen*1)". Rear Suspension
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. Some newer alignment machines are equipped with an optional "Rolling Compensation" method to "compensate" the sensors (alignment targets or head units). Do NOT use this "Rolling Compensation" method.
^ Use the "Jacking Compensation" method. After installing the alignment targets or head units, raise the vehicle and rotate the wheels 1/2 turn both ways.
^ See Instructions in the alignment machine you are using for more information.
CAMBER
1. Measure camber of both the right and left wheels with a suitable alignment gauge and adjust as necessary to specification.
Camber: Refer to RSU-28, "Wheel Alignment (Unladen*1)". Rear Suspension
2. If outside of the specified value, adjust the camber using the adjusting bolt in the front lower link.
CAUTION: After adjusting the camber then check the toe-in.
NOTE: Camber changes about 0°5' with each graduation of the adjusting bolt.
3. Tighten the adjusting bolt nuts to specification.
TOE-IN
1. Bounce the rear of the vehicle up and down two to three times to stabilize the vehicle height. Refer to "Wheelarch Height (Unladen*1)". [1][2]Ride Height (Unladen)
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on the base line of the tread (rear side) of both of the tires at the same height as the center of the hub. This will be the measuring points.
4. Measure the distance "A" (rear side) across from tire to tire.
5. Push the vehicle slowly ahead to rotate the wheels 180° (a half turn).
If the wheels are rotated more than 180° (a half turn), then repeat the above steps. Never push the vehicle backward.
6. Measure the distance "B" (front side) across from tire to tire.
Total toe-in: Refer to RSU-28, "Wheel Alignment (Unladen*1)". Rear Suspension
7. If the toe-in is outside the specified value, adjust the toe-in using the adjusting bolt in the rear lower link.
CAUTION: Be sure to adjust equally on RH and LH sides using the adjusting bolt.
NOTE: Toe changes about 1.5 mm (0.059 in) [one side] with each graduation of the adjusting bolt.
8. Tighten the adjusting bolt nuts to specification.
