Vibes from CV?

I've been dealing with these vibrations that no one seems to be able to diagnose..

I've went thru many things to try and get to the bottom of it.. Replacing Ujoints, straighten and balancing driveshafts, new carrier bearing, wheels tires balanced etc etc..

Now thing seem to go like this, I can drive it for a while, and I feel some vibes, but as the truck gets hot it will get to the point it feels like somethings about to break via vibrations, maybe even a little grinding feeling.. Also has felt much like at times, like a out of balance tire, bouncy...

Kinda hard to accurately describe it..

What this guy described is VERY similar...
THOUGHTS feedback??

 

Do you have slop or play in your CV? Also, grab a front tire and shake the $#@! out of it. Fore/aft, side to side, etc. If you feel slop there, could be a wheel bearing, too.
