Man, I've gotta be doing something wrong. I'm working on a 78 CJ with power steering. I've got the box off and am trying to adjust the worm bearing preload, but cannot get the adjuster plug or the locknut to budge. I realize this probably hasn't been moved since 78, but from other responses I thought this should move a lot easier. Could somebody tell me which one should loosen first? Are these reverse threads? I fabbed up a spanner wrench out of plate and rod, but all that happened was the rod bending and the holes on the adjuster starting to elongate. I got a 2 3/4 inch socket for the locknut, but no progress there either. I've been spraying it with blaster, but I'm reluctant to use heat cause I'm afraid of melting a seal or o-ring. I also removed the snap ring, but it didn't make any difference. It looks like the lock nut nut is threaded onto the adjuster plug body, but which of these should loosen first? Thanks for any input, this is another one day project that turned into a weeklong nightmare.
