If I can move them with the 3/8 ratchet. Those bastids are in there pretty frickin good. I tried a couple months ago and put about as much on that wrench as I felt comfy doing and they wouldn't budge.

Thanks man I kinda suspect it's just the jam nut being snugged down super tight and that's the issue. If I'm right then it'll be OK like you said to muscle them out and nothing should snap. /knocks on wood
I appreciate the responses guys. I think I've got enough out of this that I know what I need to do.
