run down to the parts store and use there U joint press... you can do it with a coulpe sockets and a BFH.... pull the C clips out of the ends....put a socket that rests on the edge of the yoke on the floor...set the u joint over it ..then get a smaller socket and from the top smack it down so the lower cap goes inside the socket...then flip it over and do it again..

it can be fustrating to do with out someone to show you but I have done q million of them....THE best way is with the U joint tool ...it looks like a big C clamp...and they usually lend them for free
