What to do? My 2005 Mountineer steering linkage and ball joints have the rubber bags but they are limp, i.e., not much if any grease in them. There are no zerk fittings, nor plugs to replace with zerks, so what to do? Anybody manage to grease these joints some other way short of taking them apart? I thought about poking a needle grease gun fitting thru the bag and then trying to patch the hole, but it seems like a bad idea, but is it any worse than the typically blow out grease bag caused by the overzealous grease gun weilding knucklehead (like me) who pumps them too full anyway?
