Front driveshaft rebuild questions-problems

I'm rebuilding a front DS to use in the rear w/ the RE H&T. How hard should it be to remove and install new ujoints? To get the old ones out, I had to beat the living snot out of them with a hammer. I figured the new ones would go in easier-WRONG! I bent and broke 3 c-clamps trying to 'press' them in, and had to resort to the hammer and socket trick, and again- beat the living snot out of them to get them in! I've never replaced ujoints before, so I don't have any experience to compare. It just seemed really violent treatment for something as precise as little ujoints with itty bitty needle bearings in them, and I'm kinda worried I might have FUBAR'd something in the process.

many people including myself use the socket method, never had a problem. you should be fine unless you can see physical damage to the ujoint.

you also have to make sure you don't knock over any of the little needle bearings. if it goes on easier then only gets hard right at the end then you probably knocked some over. make sure it moves smoothly when your done

heat the yolk up, and use a bench vise and socket method, it will go much smoother

ok- got them all in. -yep, got the right ones- 153's- Brute Force non-greasables (with the 'lifetime' lithium grease in them). Everything moves, but they are all a little 'stiff' - but they do move around, and I don't feel any scraping or roughness- should they be a little stiff, and have a little resistance to moving them by hand?

yes they will be a little stiff right out of the box but you shouldnt feel any binding because that means that you messed up a bearing on the install.

ha! if I knew what a job it was beforehand, I would have taken the shaft somewhere and let them rebuild it- or at least taken it and the new joints to amachine shop or someplace to press them in.
Oh well, another lesson.

oops... nevermind
