2006 Chevy Cobalt Noise heard on bumps

Lately I have heard a noise like something is loose in the front driver side of the car. When I go over any bump or bumopy raod sounds like something is loose. I have checks the lugnuts and they are on tight. I have noticed in the past day that when I pass over a bump or bumpy road almost a scraping scapping sounds that is periodic to ther rotation of the tire. About a year and a half a go I sldie down a street with ice and hit the curb with the passaenger side wheel. I took it to a mechanic and her said he moved something foward half and inch and recommended I get struts but due to money issues did not. And it only seems to happen on the driver side not the passenger side. Once on a falt service or on a highway I do not heard it except for a sqeecking sound I hear from the sterring wheel.
