    I have done it with a hammer BUT you need to be really careful with the needles, make sure that they are all lined up good and tey stay where they need to when you hit they have a tendency to move around, but i have done it before just take your time.

    A hammer works really good. I never have gotten a vise to work like the haynes manual describes. The haynes manual covers both methods if you want more info. A PRESS is the easiest way to do it.

    I've never used a press for driveshaft u-joints, always a hammer. If the stock joints are still in there, use a torch to melt the plastic out of them, then beat them out with a hammer.

    For axle u-joints I've never had to do it without a press but I think it'd be a nightmare.

    You can do them at home without a press. I've done all of mine (more times than I'd care to remember) driveshaft and axle. I use a 3" extenision and a socket that roughly the size of the cap (to spread the pressure out) and a 3 lb sledge they should come right out.

    Do yourself a favor before you install the new ones. Hit the bore with some emery cloth or light sandpaper and shoot some WD40 in there too. They'll go in really easy and make it alot easier if/when you have to replace them again.

    I've never actually broken an axle u-joint but I put new ones in my new (to me) front axle just because I thought they'd be nice to have, they're lifetime warrenty, and they were very cheap. Even with the press they were very difficult.

    Big C-clamp, big vise, or press is definitely the <font color=green>best<font color=black> way to go. Hammering on ANY kind of bearing is generally a <font color=red>bad thing<font color=black>. Of course, not everyone has access to the right tools, so you gotta make do with what ya got. I was lucky enough to have a big-a$$ vise left for me when I bought my house, so that's what I use.

    A vise and some cheap 3/8" sockets work pretty good.
    Make sure all the needle are in place.
    When you have them clipped or "retained", lightly tap the surrounding areas with a small ball-pien hammer to loosen it all up and make them move freely in all directions including around and around.
    Would not advise pounding them in with a hammer unless your doing it for your free for someone else... But, if that's the case whale away with a BFH and get the job done quick.
