What about the driveshaft was causing the wobble? I feel like I'm experiencing the same thing based on the location and type of vibration - also only at highway speed. I assume the root cause were the u-joints? Thanks for posting this, I've been meaning to take a similar video to try to find my issue.
Question does it feel like a propeller when accelerating? Mind comes and goes and notice a burning smell.

It was the u-joints. One of them visibly failed after a while.
Your 4x4 is engaged at highspeed? 🤔
Nope. 4wd is not engaged. It's disengaged at the transfercase. The driveshaft is rotating from the diff/pinion gear.
