Um, you bent something and now it is broken loose or is vibrating loose. Have you taken the car to a qualified BMW mechanic that will check all of the suspension?
There cold be multiple problems, and driving the car could be making it worse.
My indy charges 49.90 to put the car on a rack and check it out, that's refundable if I use them for the repair.
