If the seal or bearing is bad in the tailshaft I think that would be a result of the problem and not the cause but maybe some tranny guys might know otherwise. Was the 2 part driveshaft separated recently? If so it has to be put back exactly the way it was or it will be out of phase and you will get vibration. Usually a paint mark is put on both shafts so you can line them both back up again.

Yes...I ( just yesterday ) took the drive shaft apart and replaced the carrier bearing...and like a dumb A$* didn't even check the alingment. I will say that there is no new vibration ( or lack thereof ) after installing it. I will check tomorrow...otherwise I am screwed I suppose and will need to have it balanced?
Is it possible, that the rear brakes are dragging a little...and when they get warm start to drag and chatter??? Tonight I drove the truck again...and just like every other time, when cold it is fine...after a couple miles the shimmy starts...then the vibration and noise....tonight I pegged the brakes hard a couple times...slowed down and sped back up....and it was gone. I drove the truck another 35 miles and it did not return..... ??????????

sounds like a stuck rear brake. A couple of threads about e-brakes being stuck on this site, you probably can find one. Yours was a mild case from what I've read. Some guys said their wipers were shaking off their windshield.
