Im trying to replace the u joints on my rear axle,, 88 chevy blazer full size. No big vice either,, i USED to pund them out, but this one isnt doing it- its a factory nylon seal job on these.. Whats the best method to get em off!?

Looks like you are going to have to find a vice to press them out. You might be able to rent a tool for that, too. I pounded mine out of my Trooper years ago, but it was still a PITA. A real press would be nice.

Removal & Installation
There are three types of U-joints used in these trucks. The first is held together by wire snaprings in the yokes. The second type is held together with injection molded plastic retainer rings. This type cannot be reassembled with the same parts, once disassembled. However, repair kits are available. The third type (4-wheel drive models only) is the large constant velocity joint which looks like a double U-joint, located at the transfer case end of the front driveshaft.

■Double Cardan Joint
■Molded Retainer Type
■Snapring Type

Which one do you have?

I use a ball-joint press for my stubborn u-joints.

If you can't borrow one from a friend, some shops (like autozone) will loan them out. I bought one for around $250, it has paid for itself many times over. I know it sounds funny but I wouldn't waste my time with a u-joint press, not strong enough for the tough joints. A ball-joint press is far stronger.

I just did my front axle u-joints on one of my Jeeps this weekend. Even with the right tools it can be a sucky job.

Good luck Ron.

The U joint forks will flex and bind as you try to press them out.

Even just the weight of the drive shaft hanging in the wrong orientation will be enough.

I've got by with various size sockets or pieces of pipe and a big vise.
the trick is geting a straight push with no stress on the fork at all.
A little Liquid Wrench as well.

never had to deal with plastic inserts though.
Wouldn't take much hanging in the circlip grove or even just a burr to hang things up.

These arent budging a bit. Heated them up used a pipe over the ends to pound- and havent seen a millimeter of success.

I think stacked sockets and a big vice work better than pounding out.

When they are that hard to get out I have found getting them lined up properly while starting in the new ones to be the hardest part.....

Good luck!

hehehe,, yes it makes one feel rather inept when you KNOW about lock rings..But i had never replaced the factory jobs before, and all my books say they have JUST the nylon locks which i burnt out- squirted out the ports just like in the movies, so i "had it"....KNOTT! And yes, i should have used the STRONGER glasses i have..;-) I wont make that mistake again..

Pounding? Don't you have a cir-clip removal tool? You can file down a pair of needle nose pliers and make one, or buy a dedicated unit specifically built for cir-clip removal. The ends of the cir-clip removal tool have tiny points that fit into the little holes in the cir-clips. You squeeze them tighter than the circumference of the u-joint, and they just come out like that.

Oh! I see now that you already got them off. Good job! At least you didn't have to do it on the side of the road in Wyoming at 10 below in a snow storm. That would get you motivated.

Been there, done that. But to add insult to injury, a skunk squirted the underside of the car a few minutes before.
