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:
• Tires for improper air pressure and wear.
• Road wheels for runout. Refer to 

WT-97, "Inspection"

.

• Wheel bearing axial end play. Refer to 

RAX-5, "Inspection"

.

• Ball joint axial end play of suspension arm. Refer to 

RSU-19, "Ball Joint"

.

• Shock absorber operation.
• Each mounting point of axle and suspension for looseness and deformation.
• Each of front lower link, rear lower link, radius rod, rear suspension member, suspension arm and shock

absorber for cracks, deformation, and other damage.

• 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 Sched-

ule.

 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). Never use this “Rolling Compensation” method.

- Use the “Jacking Compensation Method”. After installing the alignment targets or head units, raise the vehi-

cle and rotate the wheels 1/2 turn both ways.

- See Instructions in the alignment machine you're using for more information on this.

REMOVAL

1.

Remove tires with power tool.

2.

Set suitable jack under rear lower link to relieve the coil spring tension.

3.

Loosen rear lower link mounting nuts (rear suspension member side), and remove rear lower link mount-
ing bolts and nuts (axle housing side) with power tool.

4.

Slowly lower jack, then remove upper seat, coil spring and rubber sheet from rear lower link.

5.

Remove rear lower link mounting nuts and adjusting bolts (rear suspension member side), and remove
rear lower link.

INSTALLATION

Note the following, and install in the reverse order of removal.
• Match up rubber seat indentions and rear lower link grooves and attach.
• Install coil spring by aligning the lower end of the large diameter

side to the step (A) between the rubber seat (1) and the rear lower
link (2).

CAUTION:

Make sure spring is not up side down.

• Perform the final tightening of rear suspension member and axle

installation position (rubber bushing) under unladen condition with
