    The U-Joint for the rear drivehshaft to axle in my 88 K5 is shot. My question is, to anyone who has replaced this part before... How hard is it to do and how long should it take. Are any special tools or a torch required? I am just trying to size up this project to see if it is something I am capable of doing myself in the driveway.

    Just about everybody here has done it many times /forums/images/graemlins/thumb.gif

    Should take 30 minutes or so.

    I use some sockets and a vise to press them out and hammer the new ones back in.

    You could also use a BFH and some sockets and pound them out /forums/images/graemlins/woot.gif

    Its real easy. The only problem is kepping the tcase fluid from spilling when you pull the shaft out. I have a plug for it but you could jack up the rear high enough so it does not pour out.

    have fun /forums/images/graemlins/smile.gif

    It's not that hard, use a socket to drive the old one out and the same to drive the new one in. Just take care that you get it in straight. After you get it all back together make sure that it is moving freely and not binding, if it binds you might have pushed the caps to far in. If it is a greaseable u-joint make sure to fill it with grease after assembly. Just go ahead and try, they are only like 20 bucks.

    I don't have a vise yet , and I am tired of hammering u-joints . Last time I changed u-joints , last week , I went to Autozone and borrowed a Ball Joint press . Best thing I ever did . I rebuilt my whole driveshaft in no time ( 3 joints ) . When I can afford it again I am buying a ball joint press for my trailbox /forums/images/graemlins/k5.gif /forums/images/graemlins/k5.gif

    I rednecked a press when i replaced my T-case and did the u-joints at the same time. Take one floor jack, two sockets, and the front axle, put them all together, and you get your press. It actually worked pretty good, not great, but it got them job done without a press or swinging of a hammer.

    Good idea, sometimes it can be hard to find a good surface to hammer on /forums/images/graemlins/waytogo.gif

    I purchased a cheap ball joint press at Harbor Freight for about $40. It was a pain to use on Ball Joints but it worked and it was cheap /forums/images/graemlins/thumb.gif

    i just replaced my rear ujoints. it took us forever cuz they had never ever been replaced and i guess chevy from the factory used some crazy plastic as a lock ring. We didnt know that we had to heat it up w/ a torch to get it out until the 2nd or 3rd one haha. After that it wasnt a problem at all. easy job.

    I just use a large C clamp, and on one side I place a very large socket, something that the cap can go inside of. On the other I use a small socket that's smaller than the cap... tighten it down and there you are...

    Simple redneck method /forums/images/graemlins/peace.gif
