An outer tie rod is bound (screwed into) the inner tie rod as described in this previous posting. WD40 was sprayed at connection between the two tie rods and the jam nut was loosened. Attempts to unscrew the outer rod were unsuccessful. Is WD40 a good penetrant or is it merely a lubricant and I need to use another product? I am open to suggestions.
