just make sure you undo all electrical connections before you get too carried away. the output speed sensor is on the top back, and is hard to see. not too difficult of a job though. Also, if you pull the t-case before you drop it, make the bottom middle bolt be last. it's a pain in the butt to get to and if you use a ratchet wrench it will get wedged in there until the t-case is moved back. enjoy.
