    How hard is it to replace the front knuckle/u-joint in my 71 K5. They look original. It looks like to me I have to pull the axle and have them pressed off. Also where can I purchase new ones? I have a Haynes manual for my K5 but it does not say anything in there that I can find????? Please help. Shes my Daily driver and I need to get her fixed before ths snow flies!!!!

    Ok, You will have to remove your:

    wheel bearings/locknuts
    bearing spindle

    once these are removed, you can then pull the shaft out. Then you will have to remove the u-joint. If it is stock from '71, it may be worth the extra cash to take it somewhere and have them remove it. I know that if they are in there for a long period of time, they will be a pain in the arse to remove.

    Once you do get it removed you can install or have someone install the new joint and then put everything back together.

    it isn't that bad of a job.

    One quick piece of advise is to get a slide hammer and a bearing spindle socket attachment fot the slide hammer. It really beats using this rather than using a hammer and a chisel to get the bearing spindle off!

    If you have anymore questions feel free to e-mail me!

    It's real easy to get the axleshaft put so you can change the ujoint (knocking the spindle off if a pain, but a rubber mallot works fine.)
    As far as actually changing the ujoint itself, take it to someone and pay the $30 to have it done. I tried everything and couldn't get them out (they looked original)
    Much harder to do than driveshaft u-joints.

    Might as well repack your bearing and get your rotors turned while you're at it.
