bench vice and sockets is safe and easy way, one socket to fit around cap size so cap will slide into it, and another socket smaller than cap bore size in yoke, to press cap through, youll figure it out, use a little oil and/or heat, if worse comes to worse then cut the u joint legs off with torch, but be careful because it doesnt take much heat before the cap on those injection plastic retained u joints for the cap to blow out of the yoke like a bullet leavinh a gun barrell.
stay oput of line with cap when heating up to melt plastic or to get caps pressed out, ive almost been hit twice to date- pretty much point blank both times, very close and it would have hurt ! when you are heating them up to get the plastic out, use just a little at first and stop, then a little more after a little bit and let it snake out of the hole for a couple seconds and dont go crazy on heat, theres not as much plastic int here as you might think, one it starts coming out, then immediately get rid of heat and go away for a few minutes. and then heat up the next one and do the same
howeverif you you are daring and want to get the caps out fast, then get helmet and leather on and hold torch on yoke atthe cap and lay the flameon it and look away and stay out of line of the cap where its going to come flying out at until it goes !boom!
but dont have a vehicle orperson in the garage that you care about though..
all done
