hey everyone, new to the site and to the off roading sport. i just bought a 1984 datsun/nissan pickup 720. 4 wheel drive with auto hubs. i was messin around one day to see if my hubs worked, and they dont, i was just wondering where i could find a pair of manual hubs for cheap. let me know. thanks.

You can probly make yours work. Just lube everything up.

what stuff do i use and how long would that take

I have not been inide the auto-hubs, BUT I've been in several manual hubs and go real light on the grease. The stuff inside needs to slide and the grease will build up so the stuff has to plow the grease, and it won't do it.

Unless the hub has suffered catastrophic fauilure (something is busted), then more than than likely it is not sliding and meshing w/the cogs.

manual hubs will stick if not used
so i would presume the same for autos
take it apart clean it with gas butt be spareing with it. lol just kiding !!! butt they say the price of gas is going up again .lightly grease it and try it out.
youll probably find the grese resembles mud
once you open it up

how does a hub go out in the first place. i know something could break, what else could happen. could mud and water cause it to rust?

all things wear with use its just the way of it

not much to break in a hub assy butt it does happen with hard driveing and failure to keep up maintence i usually grease mine every 2 oil changes or after any deep water crossing just to be safe

thanks for all the advice everyone. im learning quickly and hope to become good at this
