The throw out bearing will only make noise when you press the clutch pedal. If the clutch is new, the throw out bearing is a required replacement in a clutch job. Sounds like a bad pilot bearing. Not enough info in the question.
I had the same problm and it was input shaft bering, AND the counter shaft bering. Replace them and sloved the problm.
sounds like you need to bleed the clutch.or the throw out bearing was not installed correctly.or a bad slave cylinder.check the clutch fluid.to see if you lost any fluid if not all.
your throwout bearing is going replace it
A throwout bearing can make a whistling sound- really more of a chirp than a whistle. Unfortunately, it sounds like you are in for a new clutch assy.
I'm not a mechanic / technician , but it sounds like your clutch disc isn't disengaging completely when you push your clutch pedal in , so it sounds like a slave cylinder / throwout bearing problem. ( you could try starting it in neutral until the problem is repaired , at least the vehicle won't jump )
sounds like maybe a clutch release bearing. what vehicle
AnswerMine had the same problem at 98,000 and 181,000 miles. I suspect the pilot bushing could be some of your problem.-----------------------------------------------------------------------------------------------------------yes, most likely dry pilot bushing. This should always be replaced with clutch job and I put a little antiseize in it. I am assuming you had flywheel turned as well. It is not the throwout bearing. Why, because it is a bearing that is loaded the same way every time you push in clutch pedal, so would make noise every time you used clutch, whereas the bushing has no moving parts, the input shaft just turns inside it.
check the cat shield it may be rotten and rattling If the sound is coming from the engine compartment (or sounds like it might be)and rattles mostly without the clutch pedal being used, but seems to rattles less or even stops with the clutch pedal depressed, it could be the throwout bearing going bad on the clutch assembly.
sounds like air in the system, to properly bleed the slave cylinder you must remove the mount screws and hold it so the bleed port is up
this sounds like a bad torque converter (automatic) or a bad throwout bearing (manual)
From your description it sounds like it MIGHT be a bad throwout bearing.
If you have put it into gear and the car is not moving either your clutch is slipping or your clutch realese bearing is gone
sounds like you need greese on the throw out bearing
