I've managed to get everything unstuck and apart to replace a bad U joint. Now I can't get the old cups pressed out using a 12 ton press. I sprayed penetrating oil on, but that's usually fruitless. I've got access to a bigger press, but skeptical that that will do it. Do I dare heat the yokes to get them out? If not, other than new axles, I need an idea. Got to get back on the road/trail!
