As long as they are still taking grease and aren't damaged then there is no need to change them. Like one post stated most fittings, at least in the older equipment, are simply threaded in so the only thing you'd need to do is unscrew one and screw a new one in in it's place. If one of the fittings has old hard grease/gunk built up in the hole and won't take fresh grease, remove the fitting and clean out as much of the hole as possible with a screwdriver, etc. Then treat it like you would a stuck fitting and fill the hole with a penetrant, like PB Blaster, Liquid Wrench, etc. Then put the fitting back in and hit it with the grease gun again. It may take several times of filling it up, and you may need to wait a litle bit after you put the penetrant in to give it time to work before it thins the blockage enough to flow free. Eventually the combination of the penetrant and the force behind the grease will cause the penetrant to flow through the rest of the blockage and break it up allowing the fitting to take grease like it is supposed to. In my experience this will work 99% of the tie if your persistant with it, but there are the times when nothing works short of dissasembly of the joint and a good cleaning. Good luck.
