So I had done the simple lift test for the dif before and though it was open. After reading thiis I decided to just do a clutch dump with the steering wheel turned... and guess what... Two lines... The outside wasn't completely smooth... You could tell there was something in the tranny trying to get grip and then kind of sending it back a bit then re-engaging. I also compared to my brothers 2006 Focus ST... Did same thing clutch dump with the steering wheel turned and it was a huge difference... just burning rubber with one wheel like crazy... Dont know that it matters but I had Toyo RA1's in my car when i did this test and my brother had A/S
