PRECAUTIONS
Precaution for Working Range at a Regular Dealership
INFOID:0000000009180202
CAUTION:
The service items unmentioned on this instruction are recommended to be performed by a GT-R certified
NISSAN dealer. Because those service items require special equipment and a GT-R certified technical
staff who completed special training.
Aluminum Die-Casting Parts Handling
INFOID:0000000009163925
PROHIBITION OF WELDING OR BEATING REPAIR
• Material made of aluminum die-casting parts is heat-treated and looses strength when being exposed to
welding heat. Do not perform welding repair for cracks, damage or others.
• For aluminum die-casting parts deformation, do not perform repair by beating. Always repair by replacement
as an assembly.
CRACK CHECK
When the vehicle is damaged, always perform a visual deformation check and a crack check.
Crack Check Procedures
For a crack check, use dye penetrant inspection fluid (pre-cleaning fluid, penetrant fluid and developer fluid).
CAUTION:
Always perform a crack check in accordance with the procedures specified by the manufacturer of the
dye penetrant inspection fluid.
1.
Spray pre-cleaning fluid on the checking surface for cleaning.
2.
Spray penetrant fluid on the checking surface and wait until the penetrant fluid soaks into any cracks.
3.
Wipe off excessive penetrant fluid, and then also lightly wipe off penetrant fluid using a wet cloth.
4.
Spray developer fluid on the checking surface.
5.
Cracks, if any, are dyed red in color.
STRAY CURRENT CORROSION
• Corrosion occurs to aluminum die-casting parts by the stray current corrosion phenomenon, when directly
contacting other parts made of steel. Always apply anti-stray current corrosion paint (primer) on the mount-
ing surface.
• Clean mounting surface to prevent any foreign matter, steel powder or others from being mixed in. Always
apply the specified adhesive when installing.
• Corrosion by stray current corrosion may occur when installing with any other bolts than the specified bolt.
Always use the specified bolt that is surface treated.
• When loosening the specified bolt that is tightened, the treated surface may peel. Never reuse the specified
bolt that is tightened once.
TIGHTENING TORQUE CONTROL
Material made of aluminum die-casting parts is soft in term of hardness. Tightening torque must be controlled
exactly as specified. Always use a torque wrench to install any part to the specified tightening torque.
WARNING:
Never use a power tool to remove or tighten bolts for aluminum die-casting part to prevent damage to
aluminum die-casting parts.
General Precautions
INFOID:0000000009163926
CAUTION:
After finishing servicing, check that all the tools and waste are stored in a customary place.

MOUNTING INSPECTION
Check the mounting conditions (looseness, backlash) of each component and component conditions (wear,
damage) are normal.
Ball Joint Axial End Play
Move axle side of suspension arm in the axial direction by hand.
Check there is no end play.
CAUTION:
• 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 excessive force.
SHOCK ABSORBER
Check for oil leakage and damage. Replace it if necessary.

WHEEL ALIGNMENT
Inspection
INFOID:0000000009163931
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Jack, hand tools and mats are in
designated positions.
PRELIMINARY CHECK
Check the following:
• Tires for improper pressure and wear.
• Wheel bearing axial end play. Refer to
• Ball joint axial end play of suspension arm.
• 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 Instruction.
• 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.
• See instructions in the alignment machine.
Adjustment
INFOID:0000000009163932
CAUTION:
• This work is recommended to be performed by GT-R certified NISSAN dealer.
• Adjust wheel alignment with the vehicle in customer's regular use condition (e.g. normal stock
items), with the fuel in full-tank condition, and with no one in the vehicle.
• To adjust wheel alignment, set tire pressure at 250 kPa (2.5 kg/cm
2
, 36 psi). After adjusting wheel
alignment, adjust tire pressure to the specified value. Refer to
.
