Rattle under hood

So I have a rattle on the driver side of my truck that almost seems near the top of the wheel well, if your sitting in the truck it’s maybe even just to the right of it. I hear it going over bumps and sometimes it’s worse than others. Took it to my mechanic and he didn’t know what it was, I tightened up the wheel well itself and that wasn’t it and nothing under or in the truck seems loose. I’m at a loss so I’m seeing if anyone has any suggestions, thanks!

I had a very similar "noise" when going over small bumps, frost heaves etc with my 2010 z85 4x4. It ended up being sway bar related caused by a slight mismatch in front end height which applied constant torque upon the sway bar, the bushings and end links. Matching front end height left to right ceased a lot of the noise but the long term mismatch that was present before I bought the truck had worn out the bushings
