FRONT SUSPENSION ASSEMBLY

PFP:54010

On-Vehicle Inspection

NES00089

Make sure the mounting conditions (looseness, back lash) of each component and component statues (wear,
damage) are normal.

INSPECTION OF TRANSVERSE LINK END PLAY

1.

Set front wheels in a straight-ahead position. Do not depress brake pedal.

2.

Measure axial end play of transverse link ball joint by prying between suspension arm and front axle with
a iron bar or something similar.

CAUTION:

Be careful not to damage ball joint boot.

STRUT INSPECTION

Check strut for oil leakage, damage and replace if necessary.

Wheel Alignment Inspection

NES0008A

DESCRIPTION

●

Measure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, engine cool-
ant, and lubricant are full. Spare tire, jack, hand tools and mats are in designated positions.

PRELIMINARY CHECK

●

Check tires for improper air pressure and wear.

●

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.

Revision: 2006 August

2006 Murano

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

1.

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

2.

Screw adapter (SST) into plate body (SST) until it contacts body
tightly.

3.

Screw center plate (SST) into plate body (SST).

4.

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

5.

Place the dent of alignment gauge onto the projection of center
plate (SST) 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.)

In order to assure your safety and the efficient functioning of the vehicle,

IMPORTANT SAFETY NOTICE

The proper performance of service is essential for both the safety of
the technician and the efficient functioning of the vehicle.
The service methods in this Service Manual are described in such a
manner that the service may be performed safely and accurately.
Service varies with the procedures used, the skills of the technician
and the tools and parts available. Accordingly, anyone using service
procedures, tools or parts which are not specifically recommended
by NISSAN must first be completely satisfied that neither personal
safety nor the vehicle’s safety will be jeopardized by the service
method selected.
