I live in Buenos Aires, Argentina and after many years of searching six month ago I bought a 1986 Bronco XLT EFI . I’m still learning how to ride this beast but my experience in other fields tells that all automatic stuff stops being automatic in the worst moment (that is, when you really need them). I saw many advices as to change auto hubs for manual ones, but before doing so I’d like to check if the original ones are working and get to understand how do they work. Does anybody know how do auto hubs work in my ’86? How do I check if they do work as they should?
