Steering wheel rattle

I have a very aggressive steering wheel raddle when I drive 50mph+ or go downhill.

I did some research and replaced the upper intermediate steering shaft thinking it would solve the problem, but it did not.

The only other issue I can think of is the bottom steering shaft (u-joint) or the steering rack itself could be out.
(Pic attached with some fluid on it)

Please check out this video and give me your thoughts:

Here is a video of what the upper steering shaft looked like BEFORE I replaced it:

Have you rotated your tires to see if it went away?

 

yeah, thats a tire balance / rim issue for sure.
