Signing on. This has me wondering. Could it be a broken axle? Or the spline slipping in the deff? A bad hub does make the most sense with what information we have without seeing it at this point. Maybe remove and inspect the hubs? Was it doing this BEFORE ya replaced the U joints? Maybe the hub is together wrong.

One other thing I noticed today when driving it to work. When I am in two wheel drive and take a sharp turn I can hear whats sounds like a tinkling bell coming out of the front end. I think I am about to just start buying bearing, u-joints and new guts for the diff . Just change it all out that way I have covered everything except the hubs.Then I will really know whats going on if it keeps doing it after that.

In this mode if the truck is shaking and making very loud noises, it would have to be something with the rear driveline or the transfer case.
If it was something in the frontend, since those parts are turning, it would be gentle knocking or clicking, since they are doing nothing but just free-wheeling.

WAIT A MINUTE! Did everyone miss this? He's not even in 4x4 if his hubs are not locked in and it still does it. His transfer case is in 4x4 mode, and the front components are just free wheeling with no strain on them at all.

If he's in 4WD with the hubs unlocked, everything in the front end is turning, at far as the locking hubs, even though the parts aren't under load. If something is hitting, or there's a bad u-joint, it would still make the noise.
The fact that it's only when he turns points to the front end as that has the most parts to cause a problem. The other alternative is the rear diff because it's components are rotating at different speeds relative to each other when turning, as opposed to moving in a straight line.
The axles and front wheels are the only components that operate differently going straight vs turning.
If examining the front end comes up empty, I'd put the rear on jack stands and rotate one wheel by hand, then the other, to get some internal diff relative movement.

Wow!! This is getting complicated. I wish I was there to lay hands on it. Are you sure the hubs are coming unlocked completely??
Have you jacked it up and blocked it and rotated the wheels and shafts with it in and out of 4X4 as yet? Is there oil in all three boxes?

Nope, didn't miss it, that's why I suggested a closer examination on jack stands.
