Truck shutter at hi speed sometimes as I accelerate but mainly bad at hi speed 85 or more . Can be steady at 100 and whole truck will rumble .

I’d check anything that has to do with your suspension: steering wheel linkage, tie rods, ball joints, idler arms, sway bar links,shocks. jack the front up and see if you get any wobble up down left right. 

probably start from one wheel and work your way to the center. for the idler arms gonna have someone look at it same time someone turns the steering back and forth. 

if you find nothing in front look at back. if still nothing maybe get tires rotated and balanced and see if they can find anything.

Try driving faster, what's the worst thing that could happen with one of these trucks????

Might just be a transmission issue with the shuddering?

You're very brave (or something else entirely) considering these driveshafts are known to grenade themselves at those speeds.
