She's a 2009 AWD, and I smacked a deer with her right before this all started. It was the driver's side front, and we had to replace the radiator support arm, headlight, fender, hood, headlight, and valance. So it was a fairly bad hit. (I still have to pry the fuse box up from where it wedged itself).
The noise, however, seems to be coming from the passenger side rear. It's a steady thumping dependent on tire speed (I'd say once per rotation) and it's audible up to about 25 mph. After 55 mph, I start feeling a vibration, and the car sounds louder. The noise stops immediately when I brake, and d̶o̶e̶s̶ n̶o̶t̶ c̶h̶a̶n̶g̶e̶ w̶h̶e̶n̶ I̶ t̶u̶r̶n̶ gets louder when I turn left. It doesn't sound louder when I put down the windows. It started a week ago, and has gotten steadily worse.
The tires are in good condition; the lug nuts are tight; there's nothing hitting the drive shaft (that I can see); and the wheel wells are clear. The balance might be off, but I hear the "thump" below 5 mph, which seems pretty slow for a weight to be affecting things.
Any ideas?
