When I changed the joints in mine I found that there was a nylon type of seal in the caps that went in one side of the yoke, around the cap and outside of the otherside of the yoke. After removing the clips I had to use a torch to heat up the yoke and the nylon came out and then the caps came out very easy with a hammer and a socket as stated before. Look at the yoke arond the cap and see if there is a small hole on each side and see if there is a trace of nylon, some of mine I could see and some I couldnt. I hope this might help you out.
