Strange Vibration at 50Mph+

Recently noticed at 50mph and up there is a vibration and gets worse the faster I go. Shakes the passenger seat. I thought maybe bad carrier bearing so I check it and it has a little bit of play . So I replace it along with the middle u joint while I have it apart. Checked my other u joints and they don't have play. Drive the truck and still have the vibration. Lift the rear end of the truck up and take the wheels , rotors and calipers off and put it in drive and it does the same thing at 50mph and up. Filmed each axle hub and the shaft coming from the rear differential each place has some tiny wobble most noticeable at the shaft coming from differential connecting to driveshaft. Also listened to rear differential there is some noise coming from it , checked fluid and it looks clean no metallic flakes. Posted links to videos in comments.

Might just be wheels out of balance.

 

A warped rotor will cause vibration too.

 

Still does it when jacked up and with tire and rotor off of the truck.

 

I'm stumped
