PRECAUTIONS

PFP:00001

Caution

NES00085

●

When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.

●

Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.

●

After servicing suspension parts, be sure to check wheel alignment.

●

Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre-
oiled, tighten as they are.

Check road wheels for runout.

●

Check wheel bearing axial end play.

●

Check transverse link ball joint axial end play.

●

Check strut operation.

●

Check each mounting point of axle and suspension for looseness and deformation.

●

Check each link, rod, and member for cracks, deformation and other damage.

●

Check vehicle 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
Schedule.

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 wheel nuts (3), and install a guide bolt to hub bolt.

2.

Screw adapter into plate body until it contacts body tightly.

3.

Screw center plate into plate body.

4.

Insert plate on guide bolt. Put spring in, and then evenly screw in
guide bolt nut. When fastening guide bolt nut, do not completely
compress spring.

5.

Place the dent of alignment gauge onto the projection of 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, and replace suspect parts if necessary.

●

Kingpin inclination angle is reference value, no inspec-
tion is required. (Due to the type of suspension, the king-
pin inclination angle cannot be measured correctly using a normal alignment tester.)
