After I blew one of the factory hubs I swapped to the Warns. When I was researching it I remember reading that the factory hubs are momentum engaged, meaning that they have to be moving to get them to engage. I went to the manuals because many times I drive in 2wd until I need 4wd and sometimes that means I am already stuck.
Plus, I wanted the comfort of knowing that the hubs are locked verses the factory guessing game. If you have the factory rims and center caps you will have to widen the opening on the center caps to fit them with the Warn hubs. You can also use manual hubs off of the Nissan Hard body. They are tough to find in the junk yards because most have already been picked.
