REAR SUSPENSION ASSEMBLY

PFP:55020

On-Vehicle Inspection 

NES000J6

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

INSPECTION SUSPENSION ARM BALL JOINT AXIAL END PLAY 

Measure axial end play by placing and moving up/down with an iron pry bar or something similar between sus-
pension arm and axle assembly.

CAUTION:

Be careful not to damage ball joint boot.

SHOCK ABSORBER INSPECTION

Check shock absorber for oil leakage, damage and replace if malfunction is detected. 

Wheel Alignment Inspection

NES000J7

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 in designated positions.

PRELIMINARY INSPECTION

Check the following:

1.

Tires for improper air pressure and wear.

2.

Road wheels for runout. Refer to 

WT-6, "ROAD WHEEL"

 .

3.

Wheel bearing axial end play. Refer to 

RAX-5, "WHEEL BEARING INSPECTION"

 .

4.

Ball joint axial end play of suspension arm. Refer to 

RSU-5, "INSPECTION SUSPENSION ARM BALL

JOINT AXIAL END PLAY"

 .

5.

Shock absorber operation.

6.

Each mounting point of axle and suspension for looseness and deformation.

7.

Each of front lower link, rear lower link, radius rod, rear suspension member, suspension arm and shock
absorber for cracks, deformation, and other damage.

8.

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.

Standard value

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.

CAMBER INSPECTION

Measure camber of both right and left wheels with a suitable alignment gauge. 

Adjust in accordance with the following procedures.

If outside the standard value, adjust with adjusting bolt in front
lower link.
NOTE:
After adjusting camber, be sure to check toe-in.

TOE-IN

If toe-in is not within the specification, adjust with adjusting bolt in
rear lower link.

CAUTION:

Be sure to adjust equally on RH and LH side with adjusting bolt.
If toe-in is not still within the specification, inspect and replace any
damaged or worn rear suspension parts.

Standard value
