When hitting boost in 2nd,3rd gear , there is quite a loud hiss/chatter it sounds like a Bering/metal component .. I've been told a throwout/spigot bearing is this a likely case .. No sound in first gear at all (not that ive really tried to make the sound , babied it after sound occurred)

I just replaced the tailshaft bearing in my manual xr6t , it took alot of noise away but taking of uphill and at lock causes a knocking sound from the back only gently and quiet , nothing compared to what it was like with a f*cked tailshaft bearing .. Would this be caused by diff play ?
