So as I wait for my tires, gears, and lockers to arrive, I'm trying to think of things to do in order to get the truck ready for the meet in June. It currently has a little over 315K on it so head gasket is obvious. No issues that I've noticed with the transfer case but figured since the driveshafts would be out now's the time to freshen up other things. Anything I should consider replacing in the transfer case besides seals and fluid?
