2005 Chevy Equinox Noise when I go over bumps in road

Hi.

For about a few months I have been hearing a noise sort of like a sweek/clanging sound near the front end of my SUV. I did take it to my dealership and they said that all it was was the Hood of the SUV and they tightned it. It was a month or so ago, now the same noise is back and it is louder and sounds like it is in the front end. When I go over big bumps in the road it sounds like something is loose near the radiator or perhaps by the wheels or something. I did have a front end repair last year sometime due to a fender bender, but dearler said all was ok. I was going to go ahead and take it back for them to look at it again this week. Can you give me an Idea of what it COULD be?

Thank You
