I think you have a bent drive shaft. I had the same trouble for almost 2 years before I finally had the drive shaft looked at. I went through three pinion yokes and two t-case output bushings during the troubleshooting. The vibes would smooth out for a while when I would put a new bushing or pinion yoke in until the vibes wore out one or the other. The drive shaft looked fine until the guys at the drive shaft shop put on their balancer where you could see the wobble. Its pretty hard to discern a bent shaft unless you got access to a lathe or a lot of V-blocks. Getting my shaft re-tubed only ran about $100. It was completely worth it and solved all my problems.
