While I would think swapping 4.875 in the front AND rear would seam obvious, I agree it's the internet filled with idiots, so got to cover all bases.

I doubt its the lack of transfer case diff as I've had this car for 8 years and it didn't do this for quite a big portion of that.

I a while back had it parked for 6months. Then I regained interest and did a ton of mods, including a torsion crank. Its that first test drive after mods and sitting that it all began. I figured it's the axles, and since I have to change them I might as well 4.875 it, and boom, still same problem.

I'll Jack it up and dig in next week.
