If you have automatic locking hubs, which 90%+ of first gens do, then it's most likely going to be a broken / warn hub. You can buy manual hubs and a conversion kit that is stronger and more reliable for less than the cost of a new autohub.

they are manual super winch hubs.one of the hubs inside is worn before the inner splines of the hubs.it is like on of the washers or spacers on the axle is rubbing and grinding.any ideas.thks.

Next suggestion would be to take the hubs on both sides off and clean them out really well and check for broken pieces inside the hubs. While you have them off, jack each wheel up and check for excessive play (shake the wheel sideways and up and down) and then give it a good spin and see what you come up with.

I'm thinking either something worn / broken in the hubs or possibly a wheel bearing.

If one of the hub insides is worn it probably needs to be replaced. Do what Iron Weasel suggests and go from there but I suspect you may have to replace them. If they do look good make sure when you re-install them they are well greased, but not overly so as that can cause issues as well
