On-Vehicle Inspection and ServiceEES002CX
Make sure the mounting conditions (looseness, backlash) of each component and component conditions
(wear, damage) are within specifications.
SHOCK ABSORBER INSPECTION
Check shock absorber for oil leakage, damage and replace it if necessary.
Wheel Alignment InspectionEES002CY
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.
PRELIMINARY
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-5, "
ROAD WHEEL" .
3. Wheel bearing axial end play. Refer to RAX-4, "
REAR WHEEL BEARING INSPECTION" .
4. Shock absorber operation.
5. Each mounting part of suspension for looseness and deformation.
6. Rear suspension beam for cracks, deformation, and other damage.
7. Vehicle height (posture).
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/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to RSU-13, "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.
2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” 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 INSPECTION

Measure camber of both right and left wheels with a suitable
alignment gauge.

If it is out of the specification value, inspect and replace any
damaged or worn rear suspension parts.Camber : Refer to RSU-13, "

TOE-IN INSPECTION
Measure toe-in using following procedure. If it is out of the specification, inspect and replace any damaged or
worn rear suspension parts.
WA RN ING:

Always perform the following procedure on a flat surface.

Make sure that no person is in front of vehicle before pushing it.
1. Bounce the rear of vehicle up and down to stabilize the vehicle height (posture).
2. Push vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires at
the same height of hub center. These are measuring points.
4. Measure distance “A” (rear side).
5. Push vehicle slowly ahead to rotate wheels 180 degrees (1/2
turn). If wheels have rotated more than 180 degrees (1/2 turn),
try the above procedure again from the beginning. Never push
vehicle backward.
6. Measure distance “B” (front side).
