Nope haven't got around to it yet. I bought a used transfer case for $200 all 3 o rings for the actuator and a tube of rtv. The o rings from colonal seal just got in a few days ago so I just have to do the work and I'm feeling lazy in this heat. I'm only doing the transfer case because someone had the same exact symptoms as me sounds like a machine gun under acceleration and my transfer case was bone dry. I already lubed both drive shafts and pulled the rear diff and inspected it. It looked fine so did the gears and oil. I put it back and now I'm on the T case.
