Anyone swapped out the diff spool when replacing the gears in the center diff? I'm interested in doing this since I have it all apart but im not sure about the locking hubs or what to get. Since I also drive this on pavement a lot id like to be able to unlock the rear so i don't twist axles and wear tires out. Slee offers a full kit but only fits up to a 97. I have a 99 lC100.
