CHASSIS MAINTENANCE

MA-39

< PERIODIC MAINTENANCE >

*3: When the oil does not drop

• Visually check transmission assembly surrounding area (oil seal, drain plug, filler plug, transmission case,

etc.) for smears and leakage of transmission oil. Refer to

MA-32, "TRANSMISSION OIL : Inspection"

OIL LEVEL

CAUTION:

Oil volume cannot be checked by oil level height.

Remove filler plug (1) and gasket.

CAUTION:

Never start engine while checking oil level.

Insert wire (A) etc. from filler plug mounting hole to confirm if the
oil attaches.
• If oil does not attach at the end of the wire, confirm that there

is not leakage, then refill the oil. (This work is recommended to
be performed by GT-R certified NISSAN dealer.)

CAUTION:

Prevent foreign matter from getting into final drive.

Set a gasket on filler plug and install it on final drive, and then
tighten to the specified torque.

CAUTION:

Never reuse gasket.

BRAKE LINES AND CABLES

BRAKE LINES AND CABLES : Inspection

INFOID:0000000009161789

• Check brake fluid lines and parking brake cables for improper

attachment, leaks, chafing, abrasions, deterioration, etc.

BRAKE FLUID

BRAKE FLUID : Inspection

INFOID:0000000009161790

BRAKE FLUID LEVEL

• Check that the fluid level in the reservoir tank is within the specified

range (MAX – MIN lines).

• Visually check for any brake fluid leakage around the reservoir

tank.

• Check the brake system for any leakage if the fluid level is

extremely low (lower than MIN).

• Check the brake system for fluid leakage if the warning lamp

remains illuminated even after the parking brake lever is released.

• Check the reservoir tank for the mixing of foreign matter (e.g. dust)

and oils other than brake fluid.

CHASSIS MAINTENANCE

Check the brake line (tube and hose) for any cracks or damage.

CAUTION:

Replace with new ones if necessary.

Depress the brake pedal with a force of 785 N (80 kg, 176 lb) and hold down the pedal for approximately
5 seconds with the engine running. Check for any fluid leakage.

CAUTION:

Retighten each part to the specified torque and repair any abnormal (damaged, worn, or deformed)
part if any fluid leakage is present.

BRAKE FLUID : Draining

INFOID:0000000009161791

CAUTION:

• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it

out immediately and wash with water if it gets on a painted surface.

• Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) con-

nector or the battery negative terminal before performing work.

• Wrap the flare nut wrench with waste cloth to protect the caliper from damage.
• If the brake fluid adheres to the caliper or disc rotor, quickly wipe it out.

Remove tires. Refer to

WT-11, "Exploded View"

Connect a vinyl tube to the bleeder valve.

Depress the brake pedal and loosen the bleeder valve to gradually discharge brake fluid.

BRAKE FLUID : Refilling

INFOID:0000000009161792

CAUTION:

• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it

out immediately and wash with water if it gets on a painted surface.

• Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) con-

nector or the battery negative terminal before performing work.

• Wrap the flare nut wrench with waste cloth to protect the caliper from damage.
• If the brake fluid adheres to the caliper or disc rotor, quickly wipe it out.
• Never allow foreign matter (e.g. dust) and oils other than brake fluid to enter the reservoir tank.
• Since brake fluid is susceptible to deterioration from moisture, discard brake fluid remaining in the

container.

Check that there is no foreign material in the reservoir tank, and refill the brake fluid with new one.

CAUTION:

Never reuse drained brake fluid.

Loosen the bleeder valve, slowly depress the brake pedal to the full stroke, and then release the pedal.
Repeat this operation at intervals of 2 or 3 seconds until all of the brake fluid is discharged. Then close the
bleeder valve with the brake pedal depressed. Repeat the same work on each wheel.

Perform the air bleeding. Refer to

BR-10, "Bleeding Brake System"

STEERING GEAR

• Check gear housing and boots for looseness, damage and grease

leakage.

• Check connection with steering column for looseness.

STEERING LINKAGE

Check ball joint, dust cover and other component parts for looseness, wear, damage and grease leakage.

CHASSIS MAINTENANCE

Adjust the fluid level to the R level (B) rather than the fluid
level (A) in sports driving mode or in high road driving
mode.

Fluid levels at HOT and COLD are different. Do not confuse
them.

CAUTION:

• The fluid level must not exceed the MAX line. Excessive fluid causes fluid leakage from the cap.
• Never reuse drained power steering fluid.

FLUID LEAKAGE

Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.
1.

Run the engine until the fluid temperature reaches 50 to 80

(122 to 176

F) in reservoir tank, and keep engine speed idle.

Turn steering wheel several times from full left stop to full right
stop.

Hold steering wheel at each lock position for five seconds and
carefully check for fluid leakage.

CAUTION:

Never hold the steering wheel in a locked position for more
than 10 seconds. (There is the possibility that power steer-
ing oil pump assembly may be damaged.)

If fluid leakage at connections occurs, loosen flare nut and then retighten. Do not overtighten connector as
this can damage O-ring, washer and connector.

If fluid leakage from oil pump occurs, check oil pump.

Check steering gear boots for accumulation of fluid leakage from steering gear.

AXLE AND SUSPENSION PARTS

AXLE AND SUSPENSION PARTS : Inspection

INFOID:0000000009161798

Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.
• Shake each wheel to check for excessive play.
• Check wheel bearings for smooth operation.
• Check axle and suspension nuts and bolts for looseness.
• Check strut (shock absorber) for oil leakage or other damage.
• Check suspension ball joint for grease leakage and ball joint dust

cover for cracks or other damage.

CAUTION:

• After any collision, inspect all seat belt assemblies, including retractors and other attached hard-

wares (I.e. anchor bolt, guide rail set). Nissan recommends to replace all seat belt assemblies in use
during a collision, unless not damaged and properly operating after minor collision.
Also inspect seat belt assemblies not in use during a collision, and replace if damaged or improperly
operating.
Seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal colli-
sion where the driver and passenger air bags are deployed.

• If any component of seat belt assembly is questionable, do not repair.

Replace as seat belt assembly.

• If webbing is cut, frayed, or damaged, replace belt assembly.
• Never oil tongue and buckle.
• Use a genuine NISSAN seat belt assembly.
For details, refer to

SB-4, "SEAT BELT RETRACTOR : Inspection"

SB-9, "SEAT BELT RETRACTOR : Inspec-

tion"

in SB section.

• Check anchors for loose mounting
• Check belts for damage
• Check retractor for smooth operation
• Check function of buckles and tongues when buckled and released
