Push up / Pull down slop is what mine had before I replaced it.

There should be no movement.

Vibration is now gone.

Awesome, thanks JohnnyPopper.  I think we are starting to narrow this down.

Ill call into to Tom Woods today and see if they think i should stick with the conventional shaft (OEM) with a single joint on either end or if i should just move up to a double cardon joint.

I would drop the transfer case first.  It will more than likely take care of it.

Just wanted to post up my findings after installing the Tom Woods Double Cardan Shaft.  The vibrations are definitely less now with a proper shaft and proper angles for the double cardan.  The remaining vibration im having are likely related to the wheels i have so ill be taking them to be balanced soon.  I ran the truck up to 72mph yesterday, and the only vibration i felt was one that seemed to be tire related.


Thank you all for your help!!
