No rust, the U-joints look good actually. The car in general looks good as the previous owner restored a bunch of the major components. I'll bolt up the tire tonight and check for movement without the half shaft attached. No roughness at all the on the u-joing.
My parking brake stopped working before this issue started, so maybe it is a parking brake thing. My pads seems to be pretty close to the rotor, like right on the rotor, but not actually gripping as I can spin the rotor and there isn't any noise and/or it doesn't seem like the pads are holding the rotor from moving.

The only way to properly verify a u-joints condition is to disassemble it completely
Yes, I've read this a few times. My bad, but I figured it was the only way to see it in person and get video of it.
I had the wheels off, and the car running. The left side turned perfectly. The right side had this hiccup causing the rotor and the whole assembly to go up and down, making me thing the u-joint was binding.
While driving though, I could hear the whomp whomp whomp, which increased as speed increased. Watching the tire in my mirror, I could see the tire also moving up and down with the issue...so I'm thinking it has to be something inside of the right assembly, whether it be a bent half shaft (but looks straight), bad u-joints, bearing, or other.
