Four wheel drive binding up?

['63GENIII]

So I finally got the Dana 60r / Dana 44f axles installed, checked the gear ratios (counted teeth) and everything installed properly. Here's the problem, when I use the 4wd, it feels as though the front and rear wheels are trying to move at different speeds. In addition, when I try to unlock the hubs, it is as if everything is bound up and not only can I not unlock the hubs, I can't shift the transfer case back into 2wd from 4wd hi. I have the Rockwell T221 divorced 4.10 gears front and rear and was attempting this on snow/slush covered blacktop. I was wondering if the gear sets for the 60 are slightly different from the 44 or if there was any way that the front could be in high range while the rear was in low? Any ideas or insight is welcome. Thanks. Chris
