    I use 2 sockets that I don't use . one is just a tad smaller than the cap and the other is is a tad bigger on the inside than the cap.
    Then with a 4lb hammer I give it a few whacks and they usualy pop right out.
    Use emmory paper to clean up the shaft and always use never-seez on reassembly.
    It makes it so much easier to get it apart the next time.

    yeah hammers or a vice work fine unless you have an injected plastic type. On some models, Chevy cut a ring in the yoke and a corresponding one in the cup bearing, then filled it with molten plastic. This acts like a cir-clip that is more typically used. In order to get the injected plastics ones out you can a) melt it out with a torch or b) (I did this today) use an arbor press to exert 3 and a half tons of pressure on the cap to shear the plastic in half. After a loud *bang*, the u-joint falls right apart. The plastic sheared nicely in half and could remain in with the new clip style u-joints.

    I did my front axle u-joints. Mine were the clip type. I had to use a press, and when they came out, they nearly exploded out. They were 18 years old.

    I've found that it's oten WAY more difficult to get u-joints out of the axle shafts than out of drive shafts. Those suckers are in there TIGHT! I've pounded the daylights out of some that just wouldn't budge. A bit of work with the hydraulic press finally persuaded them to get moving. [​IMG]

    One of the main reason to touch up the yokes with some emery cloth and then never-seize before installing the new ones. Imaging what would happen if you were out on the trail without that hydraulic press when removing the old ones.
