mine was doing the same thing, hard turn while hitting a dip or pot hole, changed the hub that was loose. p/s had lots of play in it. no more light.

and then 2 weeks after changing it the light came on again, same deal turn car off it goes a way. so im thinking the other side is bad, or i got a bad new hub.

im going to have it scanned soon. and see where it leads me, i have a 3 year warranty on the new hub. so thats, that much off my mind.
