You can use a map gas torch available at any hardware store. I always use a big hammer and 2 sockets, 1 that is alittle smaller that the u-joint cup to drive it out, and another larger to put underneath to hold the yoke up and catch the cup. Going back together is easy, slide it together and the internal clips hold it together. Make sure you put the clips on the rearend part of the u-joint too, I have seen people not do that.
