Hello, in order to elliminate my driveshaft as being bad, I went and bought a junkyard one(the shaft that is in the truck now, I put the ujoints in and the rear one doesnt move freely when it is moved all the way in both directions. checked the u joints and they all seem to move freely with no binding so thats good, ...no the carrier bearing is another story. Not sure how to check it. Do I just spin the bearing and see if it is smooth or is there another way to check it. I tried to wiggle the shaft up and down and side to side on the shaft that is in the truck now and it will move a little due to the rubber surounding the bearing. I am not sure how much movement is acceptable(1/4 inch now). I am also wondering if there are supposed to be shims underneath this carrier bearing that move the bearing upwards toward the cab for correct drive shaft angle(carrier bearing bolts on top of cross member)

Why the concern, what is it doing?

Hello, the concern is that it(trhe truck is still vibrating, and I havnt solved it yet so I bought a driveshaft to compare to....I put the ujoints inthe original shaft so maybe I bent a yoke ear.....not sure but I do know the rear end ujoint doesnt move freely in its yoke...the center movement is fine, but when you move the joint to the end of its travel, it binds. On the junkyard shaft, the all the joints move freely, and the carrier bearing rotates freely too.
