Hit a curb pretty bad at about 30mph(somewhere around that speed maybe less). Anyway, afterwards I started getting a low volume thudding/grinding near my front driver's side. It was not dependent on which way the car turned, however the car had to at least be at 40mph along with a very slight vibration in the floorboards, but nothing serious. The noise popped up every few seconds but sometimes wouldn't hear it for awhile. Went to the Ford Dealership with hopes that a simple alignment, balance, and rotation would stop the noise but after driving it down the street it still made the noise. Had one of the techs ride with me to hear it but the only thing he could think of was possibly an unbalanced or dented driveshaft. We went back to the dealership and the Ford tech lifted the car and checked the wheel bearings but they all checked fine. Now, three days later, it seems to have gotten a bit worse. Now I can hear it half the time I'm driving to work, ESPECIALLY if I go around a right bend fast. The noise at least doubles in volume going 55mph around a bend (almost exclusively a right turn/bend)
