Tranfercase Problem?

Looking for some input on the latest problem. When I engage my 4wd, I get a wobble. At first I thought it was the auto hubs sticking. I took them apart and cleaned them. Did not help. Replaced with manual hubs. Did not help. Next I replaced the U joints on the axles and pulled the cover off the front Diff and checked the gears. Truck still has the wobble while hubs are locked. I have found that with the hubs in free, I can not turn the front drive shaft freely. It has a lobing feel to it. Very hard to turn and then it turns freely until it reaches the tight spot again. Seems like something is binding in the transfercase or 4wd is some what engaged. Any ideas would be great. Thanks

What do you mean by 'wobble'? Have you tried to remove the from DS and spinning the TC output flange and the pinion on the axle?

Thanks for the reply. I would say the wobble feels like a bad u joint. The part I find confusing is that with the hubs in free, I can not turn the front drive shaft freely. As I turn the drive shaft, it will rotate a half turn with a lot of resistance as if spring loaded. Then it is as if the spring unloads and the shaft rotates the other half turn and stops. I checked another SD and with the their hubs in free, the front drive shaft rotates freely. I was thinking of pulling the front drive shaft, locking the hubs and driving a few feet to rule out the front diff. Not sure what it could be, starting to think something in the transfercase went south on me.

I would do that first, yank the DS and drive it. You can also just pull the DS and test sping them by hand as I mentioned earlier

WOW. Do I feel dumb. Turns out the front u joint on the drive shaft was frozen. Much better than having a bad transfercase. Thanks for the input. I almost took it to the shop because I was fustrated.
