Actually it sounds like the pilot bearing to me, not the throw out. Usually the throw out bearing will make noise when you push the pedal down. When the pedal is depressed, the throw out bearing contacts the fingers of the pressure plate and if it is bad, that is usually when it will make noise.alright i sent a thread on here before bout this but n-e way when i crank my stang it makes this whining/roaring no vibration or nothing but when i push the clutch in it goes away an when im going down the road it makes this racket noise but when i push in the clutch or put it in neatrual it stops..guy at a local parts store said its the ''THROW OUT BEARING'' which i would be better off to go ahead an replace the clutch etc... so im buying a clutch kit for 115.00 ..so do yall think that is my problem please let me know your thoughts THANKS!
The pilot on the other hand, turns with the crank until you push the pedal down, then the needle bearings inside, stop with the input shaft. Therefore, if it is bad, it'll usually make noise because the casing is still turning with the crank while the inside bearings are not moving and are stopped with the input.
