Naaa.... not too crazy about 60mph on jack stands honestlyHave you tried it on jack stands???
You need to find out if it is driveline or suspension related.
So i only have 4 weights on the rear shaft currently... Two on each end...I just went through this on my 08 with the aluminum shaft. Balance means nothing. I had mine throw 3 of the 4 weights off the one end and it balanced with in spec. Still vibrated bad. I ended up knocking the last weight off and the vibration is gone. Inspect the shaft and see if the weights have fallen off. Also make sure the new joints move freely. A tight joint can cause a vibration as well
Soo... it's the same in 5th gear, steady vibration, thought we were onto something but negativeIs it doing it running a steady 55mph or whatever the speed was, in 6th gear? What would it do if you ran it out the same speed and held it in 5th.

you said it through 3 out of 4 on "one" end correct?

I will try the go pro idea i like that...Nothing wrong with this if you have good solid jack stands. We do this after rebuilding an automatic transmission. Run it through the gears to verify all is good.
I'd be checking all sorts of rotating parts with a dial indicator in your situation. Do you have a GoPro to video under the truck while driving?
Fairly certain mine is steel...Yes my aluminum driveshaft had 4 on each end
It's a g56 so no dice on converter lol... and yes short bed no carrier bearing, but i suppose ill have to try the jack stand ideashort bed, so no carrier bearing correct?
id agree with above... jack stands and chock the fronts. you can even put the front bumper up against a building or a concrete pole just to be safe. even if it falls off the jacks at 60 with no load the converter will just stall the motor out most likely.
x2 on pulling the rear drive shaft and going for a drive in FWD.
