I think from my searches it could be a the differential but, wanted some opinions. My 98 SVT has had a chattering/grinding sound from 1k to 2k rps with clutch fully engaged and it goes away once I pass 2k rps for a little while now sounds kinda like an old farm trucl is the best I can describe it hehe. Recently it has been accompanied by a squeal if the car has sat for even 5 mins the squeal happens once and is gone almost sounds like a belt or a tire rubbing but I know it's neither. Had another thought it also sounds kinda like a power steering pump so maybe the clutch cylinder? I always attributed it to the clutch the previous owner said it was a heavy duty clutch. It grabs hard and there is no slippage.
