Front end rattle

Hello all. I have a 2011 dc that has developed a rattle in the front end over bumps. Seems to go away when I hit the brakes. I checked the clips on the calibers and they seem to be installed correctly. I am going to bring it back to the dealer, only had it for about a month, but I usually like to diagnose the problem before I go there so there is no bs with the service guys saying they don't hear it or can't find it. Any ideas?

 

I had a front end rattle that happened every so often and after poking around a bit, I discovered it was the tire balancing weight. I jammed some thin foam behind it and the rattle was gone. It's something easy to check and don't forget to look on both sides of the tires.

 

I'll check that. Thanks
