    The front hubs are in need of rebuilding due to excessive leakage around inside.
    Is this just a matter of buying a kit, dismantling, cleaning and reinstalling with new seals?

    You mean locking hubs or the knuckles? Not much to rebuild in the hubs themselves other than to replace the spindle bearings and grease seal.

    Almost every Jeep not owned by an enthusiast needs the knuckles gone through. If you search, this will have been covered ad nauseum in the past. https://www.google.com/search?q=site:earlycj5.net+knuckle+rebuild

    You really mean roll eyes? A search might be helpful. We aren't jerks about that here.

    Depends on the condition of the knuckle ball, the kingpin bearings, and the spindle bolt holes. Could be simple, or you might find a bunch of other stuff that needs doing.

    Do you mean hubs or the knuckles? If you mean the knuckles, there's a lot of material online - https://www.google.com/search?q=rebuilding+jeep+closed+knuckle

    Timgr was simply trying to be helpful.
    It would be helpful if you could be more specific about what info you are looking for. You still haven't answered his very pertinent question. Which hubs? Wheel bearing hubs or locking hubs? Or knuckle assemblies?
    Do you have a factory style service manual? These can be very helpful for service information as well as terminology to help you ask questions that are clear for us to be helpful.

    Rolling your eyes like that does not make many of us want to help you.
    Especially since you are doing a project for a customer from whom you are getting paid, and you are availing yourself of the FREE resources and experience here.

    Was rolling my eyes at my own foolishness.
    I personally share a lot of information over the net in order to be of help to people. If I have offended you or anyone I apologize for it. Not trying to take advantage just learn about another type of older vehicle.
    After reading some of the links in Timgr's post I think it best to dismantle the front end and make notes of exactly what I need. The knuckle assemblies are where the leaks are and it seems there is one major seal that is probably the culprit.

    Thanks for your concern. I'm fine. I just wondered what you meant.

    Some of the other Jeep/4x4 sites (ie Pirate) get annoyed and vulgar when a frequent question is asked. So I wondered.

    Hope you got the info that you need. The closed knuckles can be a maintenance headache, esp. when neglected (often). So there's already a lot written about them.

    The knuckle seals can be replaced without diss-assembly, but at the very least once you've removed the old seals you should verify the knuckle bearing pre-load with a spring scale as described in the factory service manual or at http://www.4wdmechanix.com/Video-Workshop-Steering-Knuckle-Kingpin-Bearing-Service.html (I'm betting they won't come close to passing).

    Once everything is properly back together use the proper viscosity lubricant to fill the knuckles (ordinary gear oil will just leak out). The FSM calls for GL0 grease, that's available as as "Corn Head Grease" from John Deere outlets, CV joint grease will also work. You can also mix up your own "knuckle pudding", do a search here for the recipe.
