REMOVAL
1. Remove tires from vehicle with a power tool.
2. Remove shock absorber. Refer to FSU-11, "
COIL SPRING AND SHOCK ABSORBER" .
3. Remove mounting nut and bolt with a power tool, and then remove upper link from steering knuckle.
4. Remove mounting nuts and bolts, and then remove upper link and stopper rubber from vehicle.
INSPECTION AFTER REMOVAL
Visual Inspection
Check the following:

Upper link and bushing for deformation, cracks or damage. Replace it if a malfunction is detected.

Ball joint boot for cracks or other damage, and also for grease leakage. Replace it if a malfunction is
detected.
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE:
Before measurement, move ball stud at least ten times by hand to check for smooth movement.

Hook a spring balance at cutout on ball stud. Confirm spring bal-
ance measurement value is within specifications when ball stud
begins moving.

If it is outside the specified range, replace upper link assembly.
Rotating Torque Inspection

Attach mounting nut to ball stud. Make sure that rotating torque
is within specifications with a preload gauge [SST].

If it is outside the specified range, replace upper link assembly.
Axial End Play Inspection

Move tip of ball stud in axial direction to check for looseness.

If it is outside the specified range, replace upper link assembly.
INSTALLATION

Installation is the reverse order of removal. For tightening torque, refer to FSU-8, "Components" .

Perform final tightening of bolts and nuts at the vehicle installation position (rubber bushing) under
unladen conditions with tires on level ground. Check wheel alignment. Refer to FSU-6, "
Wheel Alignment
Inspection" . Swing torque

THE 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). Do NOT 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). 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're using for more information on this.
INSPECTION OF CAMBER, CASTER AND KINGPIN INCLINATION ANGLES

Camber, caster, kingpin inclination angles cannot be adjusted.

Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so vehicle will remain horizontal.
Using a CCK Gauge
Install the CCK gauge attachment [SST: KV991040S0 ( – )] with the following procedure on wheel, then
measure wheel alignment.
1. Remove three wheel nuts, and install the guide bolts to hub bolt.
2. Screw the adapter into the plate until it contacts the plate tightly.
3. Screw the center plate into the plate.
4. Insert the plate assembly on the guide bolt. Put the spring in,
and then evenly screw the three guide bolt nuts. When fastening
the guide nuts, do not completely compress the spring.
5. Place the dent of alignment gauge onto the projection of the
center plate and tightly contact them to measure.
CAUTION:

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 inspec-
tion is required.

Checking Power Steering Fluid and LinesNLS0008E
Check fluid level in reservoir tank with engine off.
Use “HOT” range at fluid temperatures of 50 to 80°C (122 to 176°F)
or “COLD” range at fluid temperatures of 0 to 30°C (32 to 86°F).
CAUTION:

Do not overfill.

Recommended fluid is genuine NISSAN PSF or equivalent.
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .


Check lines for improper attachment, leaks, cracks, dam-
age, loose connections, chafing and deterioration.

Check rack boots for accumulation of power steering fluid.
Axle and Suspension PartsNLS0008F
Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.

Shake each wheel to check for excessive play.

Check wheel bearings for smooth operation.

Check axle and suspension nuts and bolts for looseness.

Check strut (shock absorber) for oil leakage or other damage.

Check suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.
