What would that difference be? I ask, as I saw a thread from some time ago (different forum, maybe?) where
@Jerry Bransford had posted pictures of a Dana 44 axle shaft assembly, and he was commenting to be sure you had it facing the right direction. Well, the retainer plate had a lip that was to face toward the bearing. I don't recall ever reading that the assembly was from a disc brake Dana 44, but I do know that my drum brake Dana 44 has a completely flat retainer plate. It concerned me enough that I headed back out to the garage to see if I had missed something. Both the original and the replacement were, in fact , flat. So is the difference that the disc brake axle set-up has the lip, whereas the drum brake one is flat?
