Those new cold forged joints from spicer seem tough. Even though they are greasable, the trunnions are much thicker because the grease channels are smaller. The zerk fitting does weaken the cross slightly but I wouldn't worry about it if I were you. Get those bad boys installed and go hammer on 'em! K5er4life is referring to "walking" the caps out by pounding the yokes in the right spot. Works great for me but you've gotta be careful not to damage the yoke. If you have access to a wide enough vise, just use the large socket/small socket method and push them out and in.
