Most people just replace the outer spring and don't bother with the inner one.
I guess I'd be reluctant to remove that nut so it doesn't come off later. If you do take it off, Loctite the heck out of it when you put it back on.
I've never taken one off so I'm no help.
Wynn has lost a few and made his own replacements. He'll probably have some good help.
