PRECAUTIONS
< PRECAUTION >
PRECAUTION A
PRECAUTIONS
Precautions for Suspension INFOID:0000000004582063
B
• When installing rubber bushings, the final tightening must be carried out under unladen conditions with tires
on ground. Spilled 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 C
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, D
tighten as they are.
RSU
PBIC0190E
MOUNTING INSPECTION
Make sure the mounting conditions (looseness, backlash) of each component and component conditions C
(wear, damage) are normal.
BALL JOINT AXIAL END PLAY
1. Set rear wheels in a straight-ahead position. D
2. Measure axial end play by prying it up/down with iron bar or equivalent between transverse link and steer-
ing knuckle.
NOTE: RSU
About TYPE A and TYPE B, refer to RSU-20, "APPLICATION NOTICE : How to Check Vehicle Type".
Standard F
Axial end play : Refer to RSU-21, "TYPE A : Ball Joint", RSU-22, "TYPE B : Ball
Joint".
CAUTION: G
• Never depress brake pedal when measuring.
• Never perform with tires on level ground.
• Be careful not to damage ball joint boot. Never damage the installation position by applying H
excessive force.
SHOCK ABSORBER ASSEMBLY
Check for oil leakage, damage, and replace if necessary. I
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-104, "Inspection".
• Wheel bearing axial end play. Refer to RAX-4, "Inspection" (2WD), RAX-11, "Inspection" (AWD).
• 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). Never 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.
Adjustment INFOID:0000000003757281
CAMBER
• If camber is exceeds the standard value, adjust with adjusting bolt
(1) in front lower link (2).
NOTE:
About TYPE A and TYPE B, refer to RSU-20, "APPLICATION
NOTICE : How to Check Vehicle Type".
Standard
Camber: Refer to RSU-20, "TYPE A : Wheel Align-
ment", RSU-22, "TYPE B : Wheel Alignment".

• Be sure to adjust equally on right and left side with adjust- RSU
ing bolt.
• When tightening the nut firmly and checking the torque, use a wrench to prevent the turning of the
bolt.
- If toe-in is not still within the specification, inspect and replace any damaged or worn suspension parts. F
