i'm with joe there. a propane torch might be just the ticket. personally i wonder what the grease looks like if the fittings are rusted. alittle warm and new grease might be just what's in order. if ya get them open, i'd grease the hell out of them. i have an old alamite thingy ya hit with a hammer to blast tranny fluid into the fittings.. works only sometimes. heat works most of the time. i understand that some fittings are not in the best of places to change, but, well, 45 bucks-----------.
