Yea, I do see weights attached to the shafts. They are still there.
Well you are still better off to have had the work done and eliminate one more possibility.Got my tires inspected and balanced. Only one went bad, need 14.5 grams lead. That tire was trashed. Drove my truck again. Guess what? Shaky gremlin is still there. *sigh*
How's the carrier bearing? Not that I know (and maybe somebody here can chime in), but don't the sections of driveshaft need to be "phased"? Cheers!
Yes, I had the mid-section carrier replaced once back in 2000. I didn't feel anything from that one. Someone mentioned to check this part back in 2000 on this forum, under different name (pre-thedieselstop). From that, I just went up and checked it out. Sure enough, that it is really loose, not snug at all. Had hard time take it out but put new one on, it is smooth sail.Well you are still better off to have had the work done and eliminate one more possibility.
So here is a thought, have you driven the truck in various gears to determine if the vibration is speed related or RPM related?
Agree that a carrier bearing could be worn out. They should be snug and not sloppy when gripping and shaking the driveshaft by hand.
A real slow rebound is pretty typical of a dead shock. Have you checked the other side yet?When I finish post this previous post above, I was browsing around a bit on the browser. Then I went back to finish the task, I noticed that the shock absorber went back to what it was supposed to be, it seems to be very slow moving. I guess that it is still shot. It is weird to see that it moved back.
So I need to get new CPS? Not sure for ICP, is that one inside the valley, next to oil pump?Maybe the engine is running rough at those rpm's and is being mistaken as a balance issue? I could see where a semi-defective CPS or an ICP could cause this.
An accurate code read would be worthwhile.

For the codes, I just checked for that moment ago with FORScan and it didn't get any code but P1111.
