My friend had the impact bit, the screws still didnt budge. Thats why we drilled the hell out of them. I figured I'd just buy new screws once i get the new ones on. I didnt want to use a real hammer because if I damaged them and they still didnt come off it wouldnt even be drivable, I was also scared of damaging the spindell. Tommorrow i'm gonna give it all I got and beat it with a real hammer. Today the high pitched squeal has gotten to noticable. I hope the liquid wrench and claw hammer work.
