The new zerks were OK. On jack stands, I torched it. Still, couldn't get an grease into it. Mrs. Wally wanted her garage back so I took it to an alignment shop. They worked on it with penetrating oil and got grease into it. It's not real loosie goosie but I'm happy. One hour of labor charge was worthwhile to me. $92.
Thanks for your advice!
