I'm changing the U joint between the T case and the front of the driveline, and I swear this thing is trying to kill me. I finally got it out of the yoke after the first cap shattered, now I'm working on the driveline, and this sumbitch is trying to kill me too. I'm using sockets and a vise, but my problem is the fact that these things are seized in so tight.

Any tips? This is getting tiring :(

I believe you will need to use a torch to heat the area around the yoke. GM uses a plastic injected into a groove to help retain the caps. Start slowly as you dont want to overheat the metal. you should see plastic being ejected from two small holes on each side.

hope this helps!

X2 but only on the steel driveshaft, you try this on an Aluminum shaft and you will ruin it. The heat will oblong the holes in the yoke and they will expand being to large for the u-joint. I saw a kid do this at a dealership i worked at and ruined the shaft.LOL. I use a u-joint press from tiger tools but that to will not work on the Aluminum due to the shape of the yokes, those i take out the old way, hammer and sockets.

You can use a ball joint press also. It will put pressure in the right places more evenly. You can rent them for free with just a returnable deposit at your local parts store, if you don't own one.

Like above if it's the factory u-joints you need to heat em to melt the plastic which retains them.

I finally got 'er done with enough leverage on the vise. If it had the plastic, would it have C clips?

yes it would also have the clips. I you look inside the bore of the shaft you can see the groove. I usually clean that area out with a small screwdriver, or hook tool.
