Thumping noise while steering.

Sorry for the crude video it's hard to get this noise on camera. Has anyone had an issue with a noticable mechanical thumping noise that happens when you turn the steering wheel? It usually happens when backing up and only happens once each individual trip. One time it happened when I turned from a stop and accelerated. You'll see it happens towards the end of the clip. I feel like when you turn up the volume and watch it in a loop it becomes more and more apparent.

I am assuming it is still under warranty. What does the dealer say? It sounds like could be something like a rack mount or trans mount? Does it only happen at the steering lock point?
