Angry Unknown Clunk

Recently, within the past 2 weeks, I've started to hear this thump or clunk underneath the front passenger compartment, specifically under the driver side to middle. I can also feel it in the floor. At first it was occasional, but now it happens each time a make a moderate to hard turn, left or right. I'm thinking it is the steering linkage.

If anyone has any thoughts please help, my truck only has 2700 miles on it.

Still working on it. Dealer said everything looked good, but started getting the sound again.

Ya man, my 06 Duramax's body mounts were so bad, when I removed them they were almost deteriorated, I put Energy suspension mounts in and honestly that was the best upgrade to improve the ride quality I could do. They were only 3 to 4 years old also.

It was fairly cheap too..

Might look into those for this truck, but I currently have no noises. My 250 is solid as a rock.

Sounds like a loose track bar to me because it just happened to me and I felt the same noise and clunk you have described.
