My '82 RC still has the original auto hubs. Last winter it felt like they didn't engage a couple of times, so I bought some Superwinch manual hubs (400518). I am hearing conflicting advice about what is required to install them (replacing the auto hubs). Can someone set the record straight for me? I can pull the truck into the garage to do the work, but I don't want it in there taking up space for days if I tear into it and discover I need additional parts, special tool, etc. It would be nice to have everything lined up first. Thanks!
