Just did the passenger side lower control arm, bushing and ball joint, upper control arm, bushing and ball joint, and swar bar link. Now I'm on the drivers side. I have already done the sway bar link and pressed a new bushing in the upper control arm, but I can't get the ball joint out for the upper control arm. Some has obviously been down there before because the inner torx nut thingy is stripped. I went out and bought the T55 socket but now I can't even use it.

Should I just drill this out? The ball joints came with new screws, but there huge. I just used the old ones instead on the passenger side.
