I just did mine this weekend completely by myself. Its not too bad, with help, you could do it in 2 hours or less. A couple notes, if you split the transfer case from the trans, drain the oil from both. Also there is no need to drop the exhaust but it would make it a lot easier. Its a good idea to clean your cps and replace your rear main if needed. The two top bolts are star bolts, but the rest of the work can be accomplished by basic sockets and wrenches.
