Strange sounds in r32 GTS-T

[Pekatu]

Only had the car about one month and there are afew strange sounds that maybe someone here has encountered before.

NO:1, at idle, sounds sort of like a thrust bearing, but not as loud and high pitched, when the clutch is pushed in it goes away!

NO:2 when breaking just before the car stops (last 5 meters or so) the front left brake is making a "grating" sound and "feels" rough thru the pedal.

any help would be much apreciated!

Hey...

For NO:1 i couldn't tell u for sure with out hearing the car

For NO:2 may be a worn disc/rotor get it checked out and machined

[Pekatu]

that's the thing the disk look's fine and to the touch feels ok as well.

with the clutch noise could it be the clutch is not adjusted properly and is (when released) staying on a little bit?

[AeroGrace]

a friend of mine had problem #1 you described....sound goes away when clutched-in.

a mechanic told him it was his gear bearings...

[Duncan]

#1 is quite common, do a search for "thrust bearing"

[Guest RedLineGTR]

yep sounds about right.

[unwritten law]

i have the same noise with #2. Just when pulling up at lights for the last 10m there is a bit of a scraping noise, its not too bad, but i am gonna get it sused. When I bought it the guy said its had the discs machined and new pads. The discs feel pretty smooth, must be the pads...

[Pekatu]

yeah it might be gear bearings, cause the gearbox is quite noisey when driving I thought that may have been a skyline trait, what are they worth to repair?

[Duncan]

I've had a noisy thrust bearing in the gearbox for 3 years now, no problems yet!

[Jetdat]

problem no :1 sounds like the gearbox input shaft bearing...unless it is very loud it is ok and will last for a long time dont worry....it is common with skylines.

[Pekatu]

I don't understand how it can be a gearbox bearing cause it makes the noise in neutral, if it is what do they cost to replace?

[Jetdat]

yes it will make the noise in neutral, if you press the clutch it will disappear.....

i am afraid it is rather costly, so as i said if it isnt too loud dont worry, but if you insist get your gearbox rebuilt, i guess it will cost $2000 or more.

[Kinks]

If it's the input bearing it will make a noise in neutral with the clutch out because you have:

engine -> clutch -> gearbox -> diff/road

gearbox has an input and output shaft, normally these are engaged in a gear but they're not connected in neutral - but with the clutch out the engine's still connected to the input side of things so the input shaft will spin with the engine.

Have a look at howstuffworks.com, pics will help.

most likely your bearing... mine does it too its a $5 nissan part but a bitch to drop your whole box.
