Posting this pic from a factory service manual that shows the differences between the auto-locking hubs and the manual locking hubs. Had a question in the Aisin hub video that might have something to do with an auto to manual locking hub conversion. I've seen attempted "conversions" from auto to manual locking that didn't work because you need to change out all the auto-locking hub guts for the correct ones that go with the manual locking assembly. You can't just take an auto hub and slap on the dial, cover, and clutch from a locking hub. It is an easy swap though if you just get all the parts together. If I remember correctly, when you're swapping an auto-locking hub to a manual locking one on a U.S. truck you'll need the manual locking hub parts from 1986+. The auto locking hubs were an option starting in 1986 in the U.S. The early (79-85) solid axle U.S. truck's manual locking hubs were a bit different length or something. I forget exactly what the difference was, it's been a long time since I messed with it.
