When the driveshaft was disassembled to replace the carrier bearing, there is an excellent chance that the splined part got put back together in the wrong position, or "out of phase".
The two yokes that make up the front section of the shaft, when slid together and the nut put on, need to be parallel.
In the diagram below, that would be A and B. They should be aligned the same, like in the diagram. If they are even slightly off, it will misbehave. Especially when you first pull away from a stop.




Edit: I just realized after typing this out that someone (or two) already explained this. I'm not deleting it, though. I worked hard on this.

That's advice I've been taught as well, thank you for this I'm a visual person and I needed a complete diagram.
If im understanding this correctly the front yoke on the middle drive shaft needs to be vertical instead of horizontal correct? So that it matches the yoke just past the carrier bearing?




Here are pictures of the drive line from front to back
Adding links because the images are huge and I cant set their HTML values to 100%.

Also found this little gem.... Might explain that "clunk" noise I heard.

Im also thinking that it may be worn out rear leafs causing axle wrap on acceleration.
the vibration gets worse if i'm turning while accelerating or giving it more gas.

If I baby it it's not too bad, doesn't do it while coasting down a hill, only under load and only under acceleration.
Im not sure how to test it without buying a gopro and filming it..

Just had the rear drive shaft removed at the shop and drove it around in 4x4.
Issue went away! Whatever is wrong itís a driveline issue.
They are flipping the rear flange of the middle drive shaft to match the picture given to me by reserector. Hopefully that solves the vibration issue.
If itís not that itís probably the driveline angles.

Problem solved!

the rear yoke of the middle drive shaft (Marked B) needed to be aligned with the front yoke as indicated by the diagram, rotated 90 degrees.




Basically when they installed the carrier bearing they didn't mark the drive shaft and they reinstalled it incorrectly.


I would have been in the shop for another year if it wasn't for the help, thanks again everyone.
