WHEEL ALIGNMENT
Inspection
INFOID:0000000005514318
DESCRIPTION
CAUTION:
• Camber, caster, kingpin inclination angles cannot be adjusted.
• If camber, caster, or kingpin inclination angle is outside the standard, check front suspension parts
for wear and damage. Replace suspect parts if a malfunction is detected.
• Kingpin inclination angle is reference value, no inspection is required.
• 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
Check the following:
• Tires for improper air pressure and wear.
• Road wheels for runout. Refer to
• Wheel bearing axial end play. Refer to
(2WD),
(AWD).
• Transverse link ball joint axial end play. Refer to
.
• Strut operation.
• Each mounting part of axle and suspension for looseness and deformation.
• Each of suspension member, shock absorber, upper link and transverse link for cracks, deformation and
other damage.
• Vehicle height (posture).
GENERAL INFORMATION AND RECOMMENDATIONS
• 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 rack itself should be capable of accepting any NISSAN/INFINITI vehicle.
- The rack should be checked to ensure that it is level.
• Make sure the machine is properly calibrated.
- Your alignment equipment should be regularly calibrated in order to give correct information.
- Check with the manufacturer of your specific equipment for their recommended Service/Calibration Sched-
ule.
ALIGNMENT PROCESS
IMPORTANT:
Use only the alignment specifications listed in this Service Manual.
• When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Never use these indicators.
- The alignment specifications programmed into your machine that operate these indicators may not be cor-
rect.
- This may result in an ERROR.
• Some newer alignment machines are equipped with an “optional Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). Never use this “Rolling Compensation” method.
- Use the “Jacking Compensation Method”. After installing the alignment targets or head units, raise the vehi-
cle and rotate the wheels 1/2 turn both ways.
- See Instructions in the alignment machine you're using for more information on this.

Disassembly and Assembly
INFOID:0000000005514321
DISASSEMBLY
CAUTION:
Never damage strut assembly piston rod when removing components from strut assembly.
1.
Install strut attachment (A) [SST: ST35652000 (
—
)] to strut
assembly and secure it in a vise.
CAUTION:
When installing the strut attachment to strut assembly,
wrap a shop cloth around strut to protect from damage.
2.
Using a spring compressor (A) (commercial service tool), com-
press coil spring between strut mounting bearing and lower rub-
ber seat (on strut assembly) until coil spring with a spring
compressor is free.
CAUTION:
Be sure a spring compressor is securely attached to coil
spring. Compress coil spring.
3.
Make sure coil spring with a spring compressor between strut
mounting bearing and lower rubber seat (strut assembly) is free.
And then remove piston rod lock nut while securing the piston
rod tip so that piston rod does not turn.
4.
Remove strut mounting insulator and strut mounting bearing,
and bound bumper from strut.
5.
After removing coil spring with a spring compressor, then gradually release a spring compressor.
CAUTION:
Loosen while making sure coil spring attachment position does not move.
6.
Remove lower rubber seat from strut.
7.
Remove the strut attachment [SST: ST35652000 (
—
)] from strut.
ASSEMBLY
1.
Install strut attachment [SST: ST35652000 (
—
)] to strut and secure it in a vise.
CAUTION:
When installing the strut attachment to strut assembly, wrap a shop cloth around strut to protect
from damage.
2.
Install lower rubber seat.
3.
Install bound bumper onto strut mounting insulator.
4.
Compress coil spring using a spring compressor (commercial service tool), and install it onto strut assem-
bly.
CAUTION:
• Face tube side of coil spring (1) downward. Align the
lower end (A) to lower rubber seat (2).
• Be sure a compressor is securely attached to coil spring.
Compress coil spring.
• Set coil spring so that its paint marks are aligned with the
positions of 1.25 turns and 2.25 turns from the bottom end
of the coil spring.

INSPECTION AFTER INSTALLATION
1.
Check wheel sensor harness for proper connector. Refer to
BRC-110, "FRONT WHEEL SENSOR :
.
2.
Check wheel alignment. Refer to
3.
Adjust neutral position of steering angle sensor. Refer to
BRC-9, "ADJUSTMENT OF STEERING ANGLE
SENSOR NEUTRAL POSITION : Special Repair Requirement"
.
Disposal
INFOID:0000000005514323
1.
Set strut assembly horizontally with the piston rod fully extended.
2.
Drill 2 – 3 mm (0.08 – 0.12 in) hole at the position (
) from top
as shown in the figure to release gas gradually.
CAUTION:
• Wear eye protection (safety glasses).
• Wear gloves.
• Be careful with metal chips or oil blown out by the com-
pressed gas.
NOTE:
• Drill vertically in this direction (
).
• Directly to the outer tube avoiding brackets.
• The gas is clear, colorless, odorless, and harmless.
3.
Position the drilled hole downward and drain oil by moving the piston rod several times.
