Please do I love hearing how people experience, diagnose, and then fix issues like these. Keep in mind that's just a hypothesis not a definitive explanation. Jack the front up and grab the wheel at 12 & 6 and try to wiggle it, then again at 3 & 9 looking for any play at all. I know it's scary but replicating it can be helping in narrowing down the cause (ie. does it only do it turning left or right, only at or above a certain speed, what about turning from a stop at a light, etc..). I had this same issue and it damn near threw me off a left-sweeping overpass onto the interstate below. Ended up being loose bearings.
