I've also done this complete job many times. Unless you have access to a very heavy duty press and lots of collars and pipes I'd bring the axle shaft and new pieces to a machine shop to be pressed off/on. Follow trichard's directions for axle removal/installation. If you attempt the complete job -- grind a groove across the width of the retaining collar and then set the works on a solid surface with an "anvil" under the retaining collar and the groove facing up--strike in the groove with a chisel to crack the collar--then it can be pressed off (it fits REAL tight). The inner seal in the axle tube can be "hooked" out. That seal keeps the differential oil from reaching the sealed outer bearing. The outer seal keeps water/dust from reaching the bearing. -- Dave
