Whirring/dry bearing type noise

Alright guys, I noticed that right about the firewall hump area I have this sound that kind of sounds like a dry bearing/whirring type noise. I think it goes away when I clutch in, but in neutral it makes said noise. Is this indicative of a pilot bearing?

Mine does it also, did it when I first got the truck but then stopped, started again a few days ago but mine sounds like the through out bearing is slipping on the pressure plate and if I push the clutch in a little it stops, I've looked for any type of adjustment but can't seem to find anything, so good luck maybe somebody can answer both of our problem, sorry to jack if yours is a different sounds or problem.

throw out bearing. That's exactly what mind sounded like, Thought it was the pilot bearing since it stopped when I pressed the clutch but it ended up being the throwout

So how did you fix it? New bearing or did you adjust something?

You need a new throwout bearing.

Think about it this way. When your clutch is engaged the input shaft is moving at the same speed as you flywheel meaning that the pilot bearing is not spinning. When you disengage the clutch the input shaft stops to allow you to shift the transmission while the flywheel keeps spinning meaning that the pilot bearing is spinning. Plus I know that the gas motors use a bushing instead of a bearing. But I've never had a clutch out of a diesel so I'd be lying if I told you that I knew whether it is a bearing or a bushing.

The input shaft doesn't stop moving when you push in the clutch, only at a stop, when your in motion the input shaft is still moving because the output shaft is still spinning, and they move together, the input shaft speed slows down between gear changes but dosnt stop.

So what can happen with this going bad? When I do this job I am doing clutch etc. so I'm hoping to string it out for a bit.

I was hoping it wasn't the pilot bearing/bushing because I've heard if that goes one can bust their input shaft on the trans...

Mine does it too. In neutral, in gear moving, but it stops if you just slightly push the clutch in. Mines been doing it since I sat in traffic for 12 hours and had the clutch in most of the time (we were constantly creeping along). I'm not worried about it.

If it locks up it will chew the fingers off of the clutch and you will not be able to disengage the clutch.

you might get lucky and be able to run it a while. When mine went it just started making a horrible squealing noise when I clutched but still was workable. Shop found the being literally in pieces when I finally got it there. It blew in nc on my way back home to pa.
