help please?

I was in an accident not to long ago and i just go my car back. but when i drive now i here a loud noise comin from my rear wheel on the side of the accident . i took the wheel off to see if n-e-thing was bent and rubbin but it’s seems to be ok. please help i have to drive with my system way up to block out the noise. thanx

what type of noise is it? cause if its just a squeeling noise it could just mean you need new pads.
