So I just got my M5 a couple weeks ago and when I'm going around corners at around anything over maybe 40mph I get this slight feeling that something's dragging it almost feels like it's the stability control dragging the front outside wheel slightly. I'm not sure exactly what it is. Anyone ever feel anything like that? I was wondering maybe it's the diff what are the signs that you need to service the diff? I have 78k miles it feels like it's something in the front though. I've already checked to make sure that nothing is physically dragging so it's not that.

Thanks for the help ahead of time!
