An outer tie rod is bound (screwed into) the inner tie rod as described in this previous posting.
I will replace the tie rods, but plan to keep the jam-nut. If I were to apply heat from a propane torch, how would I know when to stop applying heat? As I understand it I should just let it cool down (~30 min) and then try to wrench it. Seeking any best practices and recommended youTube videos on the subject matter.
