I wish I could use his computer better.
But if you go to the Pirate4x4 site and do some real marathon reading, you will find that 14 bolt axel will take a eaton dualy hub BUT you need a DIFFERANT outer bearing, Witch is out there. The reverse swap needs to have the Eaton outer spindle machined to the correct size to work with the 14b outer bearing. I have the links that only eluded to this,but I looked up the numbers on the bearings and the bearing to put Eaton on a bolt is there, and that will give you a gear range that will let you go TO fast for the HUCKS brakes and kill the useability of the truck. I was looking at this swap to get away from the hi price of bearings and no new gears, and re-setting them due to wear is a pain. A 4.10 is far better ratio for my 46 1 ton and is about as far as I would go. The 14b has more options and cheaper.
