Aiming AdjustmentINFOID:0000000001704409
The front fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing
aiming adjustment, make sure of the following.
• Keep all tires inflated to correct pressure.
• Place vehicle on level surface.
• Set that there is no-load in vehicle other than the driver (or equivalent weight placed in driver’s position).
Coolant, engine oil filled up to correct level and full fuel tank, spare tire, jack and tools are properly stowed.
Adjust aiming in the vertical direction by turning the adjusting screw (A).
1. Set the distance (C) between the screen and the center of front
fog lamp lens (E) as shown.
2. Turn front fog lamps (1) to ON.
3. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone (A) is as shown.
NOTE:
When performing adjustment, if necessary, cover the headlamps
and opposite front fog lamp.

On-Vehicle Inspection and ServiceINFOID:0000000001703712
• Check the axle and suspension parts for excessive play, wear, or damage.
• Shake each rear wheel to check for excessive play as shown.
REAR WHEEL BEARING INSPECTION
• Move wheel hub and bearing assembly in the axial direction by hand. Make sure the axial end play is within
specification.
• Check that the wheel hub bearing operates smoothly.
• Replace the wheel hub assembly if the axial end play exceeds specification, or if the wheel bearing does not
turn smoothly. Refer to RAX-4, "
Removal and Installation".
CAUTION:
The wheel hub assembly does not require maintenance. If any of the following symptoms are noted,
replace the wheel hub assembly.
• Growling noise is emitted from the wheel hub bearing during operation.
• Wheel hub bearing drags or turns roughly.

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 AlignmentInspectionINFOID:0000000001703737
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
.
3. Wheel bearing axial end play. Refer to RAX-4, "
On-Vehicle Inspection and Service" .
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-12, "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.
