I need to replace my u joints on my drive line. Can I do this on my own or is a shop needed? If I can do them at home what is involved?

Check on YouTube for how to videos. A u joint is basically a u joint, so once you know how it's done you can decide if you can do it. Most basic tools include a large hammer and some different sized sockets.

If you have a 2 piece drive shaft mark or note how the 2 halfs are installed...
Mine was balance with all grease fittings inline..
It most like has been balanced before in its current orientation so after you do the u joints you want it to go back in the same way....

On my '73 620, it took a hydraulic press to get the little buggers out, after popping the 'C' clips off, and it was still a pain in the butt.

44 years has a way of gluing things together...

"All of a sudden it started making noise, then started losing power. I limped the car home and tried to get it up the driveway, the engine just died."


Why do people do this?

A $100 tow bill is never as much as the extra damage you cause by trying to "limp the car home".


Don't be that person !

Yeah, that's a good point. Usually a hammer will do the trick, but if you beat them that hard, you may do some damage to the yokes.


Wouldn't hurt to try. If you can't get them done, your local driveline shop should be able to get them done for little money. They probably won't use customer supplied joints though.

mine was on a 510 and had a bitchen time so I took it to a driveline shop.  If you do, they like to replace it with their own ujoints.

Probably better if they use their parts.. if one if bad they can grab another one at no extra cost to you...
I had my 3 u joints done and 1 I brought had play in it new in the box... luckily they replaced with one they had and didn't put the shitty one in just because I brought them the parts... they gave it back to me so I through it in their trash..

I've changed out many over the years on different vehicles. Most from the 70's and 80's and its not hard if you know what your doing. I'd say look at YouTube to get an idea of the process then if you have the tools go for it. Once you've done it a few times it gets easer. Just use new parts. Tools you need will be a bench, vice, flat screwdriver, big ball ping hammer, old socket to knock or drive out old joint after removing the c clips. Use grease to keep those little roller bearings from falling out.
