    I constantly keep breaking the U-joint on the rear drive shaft at the t-case. I can only drive for about 1 to 2 days and then it breaks. I had 1/2 ton running gear with 3.08's and it was doing it, then I swapped out 3/4 ton running gear with 4.10's and it still does it. So I swapped out the drive shaft for anothing thinking that it may have been out of round or balance, but this one keeps doing it to. I have checked the t-case fluid and changed it. I only have a four inch lift and my blocks are slightly shimmed, so I don't think it's the angle. I have a NP203 transfer case. Any help would be greatly appreciated I would love to be able to drive this thing.

    shim the t-case down with the factory round stock. than ditch those blocks for non saggy springs and a set of ORD shackle flips

    how are your angles? How extended is your drive shaft out of the tcasE?

    If you're breaking u joints, they're binding, without question.

    I'd imagine axlewrap is causing the binding though...lose the blocks and it will probably stop binding.

    This is what happens with extreme axle wrap.
    You dont have to worry about the u-joint just the yoke /forums/images/graemlins/doah.gif
