OK...my friend came over this morning so i could show my friend my new exhaust system (GT takeoffs with 40 series flows). anyway, when i went to start the car. i pushed the clutch in and there was this loud squeak comin from the car. i was like WTF. so i let the clutch out and push it in again. same sound. so i had my bro come out and push the clutch in while i listened and there was the same sound. is my throwout bearing starting to go or something, cuz it jsut started doin this this morning, or at least i never noticed it before. also, wut exactly does the throwout bearing do. is this something i should get looked at right away or can i leave it for a little while?
