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.

thanks, Leve. I'm a little confused (nothing new) but all the manuals say this has to be done off the vehicle.

You loosen the locknut first, then the adjuster plug. They are right-hand threads. Righty-tighty, lefty-loosey. And you're right about the heat - Don't!

If you can't move the plug, tap vigorously against the side of the housing all the way around plug, as if you're trying to drive the outside threads into the plug. That should break it loose.

It finally came loose. I cleaned up the threads pretty good, so hopefully next time it won't be such a pain. I should be able to try this out tomorrow, along with putting on the new steering box brace.
