Okay, I don't have trouble changing the joint, since this is pretty much a straight forward deal and this is the ONLY vehicle that I have EVER had this trouble with. As for grease, if I go under the truck for any reason, other than common sense ones... dropped something and it rolled under, etc..., the grease gun goes with me, along rags. It might be the rear end is FINALLY dying since I changed my exhaust manifold a couple of days ago, and can actually here what noises the truck makes, and I hear a light "growl" or whine every now and again at low speed that sounds like it is coming from the rear end. This is most likely the problem, so I guess that I may end up parking this one sooner than I expected too.
