Thank you for the response.

I'm at 94,000mi, but all my vibration issues came about after hitting a massive pothole (blew a tire, bent a wheel, and tore up my undercarriage shield). The tranny/engine mounts seem to be mentioned a lot, sounds like it could very well be that.

Is that the Giubo or Flex Disc?

So far from all the threads I've read on vibration, the most common culprits seem to be:
  • Wheelbearing
  • Driveshaft unbalanced, BMW Giubo / Flex Disc
  • Bent Hub
  • Worn bearing
  • Front axle shaft CV joint
  • Control arm or Control arm bushings

Since I had TWO mechanics look at the car, one just re-balanced all four wheels and said it should be fine. The other said he didn't see anything broken, and that my front two wheels weren't straight, and that could cause the vibration (I switched to my winter wheels/tires, and vibration was still there; thus eliminating the non-straight wheel theory).
