I have researched this problem, but I have a couple hang-ups. Shifts into 4x4 fine not bound up. When I attempt to drive with it in 4x4 the truck shakes really, really bad. So I unlock the hubs. I got under the truck with the hubs unlocked and rotated the front driveshaft to check for play, bad u joints, leaks, etc. I noticed fluid on the t-case, but I'm not sure exactly where it's coming from yet. joints seem good.
I can rotate the driveshaft 360, but at about 180 it gets harder to rotate. It spins smoothly, but with more effort (I have to use two hands). Once I hit about 360 it is easy again for about half the turn and same thing happens. No scrape or grind feel or noise.
So I am looking and listening and what I noticed was that the front axle and the transfer case flex when I hit the "tough" part of the rotation. I can see the bottom of the axle diff. housing and the transfer case flex as in push away from the driveshaft. It isn't much obviously but enough for me to say "***?" I don't know much about the TTB and I'm hoping I don't have to tear apart the whole axle to get at the gears but if so I am looking for some trouble shooting advice AND some instruction on how the hell to get at the front axle efficiently. I will get a video tomorrow if I can. Thanks!
