Truck has bouncy shake like out of round steer tire

So a month ago I hit a blind water covered pot hole at a shippers lot. Ever since that night, it's got this bouncy feeling which seems like front area. The fender mirrors shakes up and down.

What my shop has done so far, new tie rod, alignment, mounted 2 brand new tires to test, didn't solve the issue, checked the bare wheel to see if it's bent. Wheel is fine, they checked the king pin, it's fine.

I don't know what else it is, they suggested that it's probably shock. Or drive tires. Drives are less than 6,000 miles old. So I doubt it's the drives.

What else could cause this. It is very noticeable at between 50 to 57 mph. From 60 to 65 it isn't too bad just comes and goes. It then is noticeable at 70+ just like 50-57 just not so constant like low speed.

 

I have a appointment at different shop tomorrow at 8am. I'll have them check the drive tires. No one has equimpent to balance super singles. So i don't know how they will do it but I will let them know to check the drive tires.

The steering wheel does not move or shimmy around, the shifter stick bounces when this bouncing happens too.

 

They checked the drives for out round, found one out of center, centered it and took for drive, no change...

Checked motor and Trans mount, looks good.

Checked driveline all look good including yoke.

Next right now they are removing the centeramics and take it for test drive.

 

Well after so many hours into it, we couldn't find anything, when I got it aligned 2 weeks ago, it was fine, no bent axles.

With the centeramics off, still no difference.

I then thought of this, why not make a magentic mount for my GoPro, so I did and put it in several places, looks like its coming from the drives. So I put it on the frame to view the shock movement. Looks like the rear rear right tire is out of round.

The video starts with a view of the transmission to show you what the bouncy feeling is like. Then it shows rear rear left, then rear front left (that part is long just move up the video a little to get to next shock), next is rear front right, rear rear right, front left, and front right.

The road I tested on is very smooth, it was just recently paved a year or so ago.
