Just as the title says my truck has a bad driveline vibration that I can feel though the wheels when accelerating And it progressively gets worse from 30 miles an hour and up

Sounds like your rear drive shaft may be out of balance? See if the balancing weight has come off recently.

first thing to do is check the u-joints in the driveshaft. a weight coming off is rare unless you hit something.
to check the ujoint. raise the rear tires off the ground and support with jack stands.
grab each side of the flange and twist it for play. also push up and down to check for play. look for rust spitting out around the ujoint caps.

My first instinct was driveshaft or u joints so I will check both those after work tomorrow

Tires need balancing?

I had the same thing.

I had a good tech go through mine.

And YES, it was the rear drive shaft U Joint. After taking it off, there was just a handful of rusty dust pouring out.

After a new U Joint, it was solid box platform up to 80.

Sounds like a U Joint.

The alignments still good and I haven't lost any wheels weights

I tried to powerbrake it but not spin the wheels and the vibration wasn't there but came back when I starting accelerating so I knew it was rotational. I left this morning however, and nothing. No hum/vibration at any speeds. I know it wasn't engine related so I have idea how it has gone away

Clicking noise in reverse? Definitely u joint?

I had bad you joints but as fate would tempt my vibration came back from 45 to 65. I put on brand-new tires with the same tread pattern and everything is now better than a Rolls-Royce.
Nothing more frustrating than going on a long trip and feeling your internal organs shuttering up-and-down north to south and east or west.
But this is all after a lot of professional technicians that have gone through every single spark plug everything else.
The reason why I failed to do the most simple thing was because I had tires from the original owner that had a 11/32 tread. Cooper H/S Discoverer. The Cooper's were almost 200 bucks a tire. Nevertheless, the reputable name, high price Tire did not perform as well as my Walnart General Grabber STX.
PART OF MY POINT IS THAT YOU DO NOT GET WHAT YOU PAY FOR.
Don't give up on your vibration because you will eventually find it!!
