about a month ago i hit a curb with my rear wheel pretty hard trying to avoid a crash and it destroyed my wheel and my alignment so i got new wheels and tires and an alignment but i still get alot of road noise it sounds like i have big mud tires and i get a bit of viberation do you think i bent some thig like a hub or bearing ? i dont really know how the rear is put together any help would be great i dont know what else to do. the tires are falken zx 912 265 35 18 and the wheels are rota grids18x 9.5 + 20

 

Does it only make the noise/vibration when you turn one direction? Sounds very much like a wheel bearing to me. You can try and jack up the car so the tire is off the ground and shake the wheel in question up and down, side to side and in and out. If you feel any play, it's almost certainly the wheel bearing. If I were you I would go to the dealer, tell them your car sounds like it has big mud tires on it, and have them deal with it (assuming its still under warranty)

 

why did you go with a 35 profile on the tires? less rubber = more road noise and vibration. The type of tire matters too. I've never owned a set of falkens, but they might be louder and absorb less of the shock than the stock advans. In fact, I'd be surprised if they didn't!

 

i went with 265/35/18 because the wheel is wider so it makes the same size side wall . i dont want to take it to the dealer because i have tein springs and my wheels are wider than stock so i think they will blame it on that

 

Maybe the wheel bearing is toast.

It really could be a million things since you did hit hard enough to destroy a wheel.
