Trying to remove the u joints on a 1992 Chevy 3500 pickup. I got the u joint removal tool (the one that looks like a really heavy duty c-clamp) and pushed the cups as far as they will go on one half of the u joint. Now, one of the cups is pushed into the middle of the yoke and the other cup is sticking out the other end of the yoke. My problem is that I can't get the yoke to let go of that cup. It's sticking out about half way, but I can't get a good grip on it to pull it out.

Is there a method for doing this that does not involve a cutting torch?
