please help me identify/diagnose this sound

[leegf]

i am getting the following sound from underneath the car after i've driven it pretty hard and i'm idling in neutral with the clutch out. as soon as i clutch-in the sound goes away. i also don't get the sound when the car is cold or after i've only driven it lightly without really pushing it. any idea as to what it might be?

thanks in advance.

Have you tride to change the clutch it might be that its scrachig your presshur plate??

That noise is probably from wear in the transmission input shaft bearings since it only occurs with the car stationary, the transmission in neutral, and the clutch engaged.

A change of transmission fluid to RedLine MTL may reduce the noise. Unless it gets a lot worse it isn't anything to be concerned about.

Sounds like a throw out bearing taking a dump...change it when you do your next clutch job.

Hmm only if he were driving a POS Bronco 2. I say front bearing as noted above. Could also be the lay shaft bearings.

im thinking clutch or pressure plate

funny

Im having the same noise. I'm thinking throw out bearing or at least hoping. I pulled my trans last night and should have a new one in a day or so. But I will changing the clutch and press plate, as well as get the fly resurfaced. I will let you now if it goes away.

Quick question tho, Does it make that sound when rolling or stopped in neutral?

Mine makes it when driving and gets faster the more speed I pick up. By the time I get to 45-50mph its just a loud hum. But if I'm stopped it depends where it lands if its loud or not, but if it's loud when I'm siting in neutral I literally roll forward about a foot then it goes away or if I push the clutch in it always goes away.

thanks everyone for chiming in. based on the first couple of responses here (as well as discussion offline with others), it doesn't sound too serious and may even be fairly common in the transmissions for these cars?

Quick question tho, Does it make that sound when rolling or stopped in neutral?

i'm not able to hear anything when the car is in motion, even when it's coasting to a stop. that doesn't necessarily mean the sound isn't there; it very well could be, it's just that the sound of tire noise, engine noise, and other ambient sounds is greater, and thus, masks this particular sound. even at idle it's not an especially loud noise.

could it really be the throw out bearing? it's not moving when your foot isn't on the clutch. I think it's the input shaft bearing as Jim said. TOB would probably lead to engagement issues as well.

i have to 100% agree.
clutch in, noise goes away = transmission input shaft bearing.
clutch out, noise goes away = bad throw out bearing.
