Okey dokey, so please just confirm if I'm right on this.. if it doesn't have the servo on the transfer case, then it's pre-xdrive and I can pull fuse #46 and that will disable the front end from trying to pull load (and if I disconnect the front drive shafts the truck won't move). If I have the older version, then simply pulling the front drive shaft will isolate the front end and allow the truck to move under rear wheel power only. Am I right on this?
(And thank you all for all the informative help!)
