2022 Frame Replacement - What is this noise?

Hi All,

Have a'22 TRD ORP lifted 2.5 inches with an Icon lift. Looooooong story, but the truck has almost 7k miles but is on its second frame. The frame replacement was done by the Toyota dealer I bought it from, who also did the Icon lift/wheels/tires (bought new with lift/tires already done).

The dealer did a great job with the frame replacement, but there is some sort of pop/bang still lingering after a few attempts to remedy. Video attached. It only occurs at low speeds, not when going over bumps, usually in reverse or coming to a slow stop, sometimes when the wheel is turned. I feel like it is correlating with the steering somehow.

I know this is very little info, and virtually impossible to diagnose over the internet. Just hoping for some constructive feedback as the truck has been at the dealer a few times now trying to narrow it down.
