Throwout bearing

Throw up bearing LOL. New are prepacked with grease ( not easy to grease ) so they will be tight. Used goes away and gets noisy after the grease is gone. Old school diagnosis... If you hear a noise with clutch pedal depressed, thats the throw up bearing. If the noise reduces with clutch pedal depressed, thats the front bearing in the trans.
Thanks for your response.. I knew the noise diagnosis when pedal is depressed thing..but wasn't sure if there was a way of checking when it's in my hand.. Throw up bearing...lol
