Sounds like it might be worthwhile to pull the hubs apart and clean/inspect/repair them. They should be pretty near foolproof. I'd bet cleaning them up and re-packing them with a light grease would make them work right,provided there's no chewed up parts inside. If you have a warm place to work on it,that'd be a good time to re-pack your wheel bearings and look at the front brakes. It's a lot easier to do it all in one stop than to have to shut it down twice for similar services.
