PRECAUTION

PRECAUTIONS

Precaution for Working Range at a Regular Dealership

INFOID:0000000009180202

CAUTION:

The service items unmentioned on this manual 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.

Spray penetrant fluid on the checking surface and wait until the penetrant fluid soaks into any cracks.

Wipe off excessive penetrant fluid, and then also lightly wipe off penetrant fluid using a wet cloth.

Spray developer fluid on the checking surface.

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.

Inspection

INFOID:0000000009163930

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.

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

RAX-4, "Inspection"

• 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 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.
• 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

, 36 psi). After adjusting wheel

alignment, adjust tire pressure to the specified value. Refer to

WT-13, "Tire"

TOE-IN

Remove rear diffuser. Refer to

EXT-41, "REAR DIFFUSER : Exploded View"

< PERIODIC MAINTENANCE >

WHEEL ALIGNMENT

Adjust using the adjust bolt (2) of rear lower link (1).

CAUTION:

• Always evenly adjust both toe-in alternately and adjust

the difference between the left and right to the standard.

• Always hold the adjust bolt firmly when tightening nut.
• Always adjust to toe-in. The toe changes, depending on an attitude change or a permanent set of

bush. Accordingly, the state of the front wheels change to toe-out and the rear wheels, toe-in. If
the wheels change to toe-out, tire partial wear is accelerated and local heating may be acceler-
ated in the inner side of tires.

• Engaging in performance driving on a racetrack and ultra-high-speed driving, be sure to adjust

toe-in to 2.0 mm (0.079 in) or less. If used beyond this range, it is not covered by the warranty.

CAMBER

Remove rear diffuser. Refer to

EXT-41, "REAR DIFFUSER : Exploded View"

Adjust using the adjust bolt (2) of front lower link (1).

CAUTION:

• Always hold the adjust bolt firmly when tightening nut.
• Always check toe-in after adjusting camber.

Setting guide depending on the customer’s driving

• Adjust wheel alignment to the customer’s driving style.
• Never set to toe-out.
- Always adjust to toe-in. If the wheels change to toe-out, tire partial wear is accelerated and local heating may

be accelerated in the inner side of tires.

- For the above reasons, always adjust to toe-in for the vehicle of a customer who drives on a racetrack.
- Engaging in performance driving on a racetrack and ultra-high-speed driving, be sure to adjust toe-in to 2.0

mm (0.079 in) or less. If used beyond this range, it is not covered by the warranty.

• When driving on a racetrack, recommend to adjust the alignment to the “Performance driving on a racetrack”

setting. If the negative camber angle is insufficient driving on a technical course including many tight turns
may result in wear on the outside of the tire and this can cause an accident. [To avoid uneven wear, servicing
the vehicle after performance driving (at the customer's expense) is recommended to result the alignment to
the original setting.]

• Wheel alignment can be changed in process of time and mileage, as suspension parts do not adjust to each

other up to the mileage of about 1,000 miles or 2,000 km.

• Remarks for up to the mileage of 1,000 miles or 2,000 km
