One other question, when you replaced the t-cases, you replaced everything from the transmission back to the driveshafts? I ask because if you did, that eliminates the center differential as a problem. I've never looked at the transfer case and I'm not sure if you could replace the t-case without replacing the center diff. I've always assumed that the center diff was part of the t-case, but assuming can be stupid sometimes.
