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.
