PRECAUTIONS

Caution

NES000IM

●

When installing rubber bushings, the final tightening must be carried out under unladen conditions with
tires on ground. Oil might 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.

●

Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-
oiled, tighten as they are.

FRONT SUSPENSION ASSEMBLY

FRONT SUSPENSION ASSEMBLY

PFP:54010

On-Vehicle Inspection 

NES000IQ

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

INSPECTION OF UPPER LINK BALL JOINT END PLAY

1.

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

2.

Place an iron bar or similar tool between transverse link and steering knuckle.

3.

Measure axial end play by prying it up and down.

CAUTION:

Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.

SHOCK ABSORBER INSPECTION

Check for oil leakage, damage and breakage of installation positions.

Wheel Alignment Inspection

NES000IR

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

Check the following:

1.

Check tires for improper air pressure and wear.

2.

Check road wheels for runout. Refer to 

WT-6, "ROAD WHEEL"

 .

3.

Check wheel bearing axial end play. Refer to 

FAX-5, "WHEEL BEARING INSPECTION"

 .

4.

Check transverse link ball joint axial end play. Refer to 

FSU-32, "INSPECTION AFTER REMOVAL"

 .

5.

Check shock absorber operation.

6.

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

7.

Check each of suspension member, shock absorber, upper link and transverse link for cracks, deforma-
tion and other damage.

8.

Check 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
Schedule.
