Not hardcore just need help asap. Replacing tre's on 04 Chevy Colorado. Can't get the jam nuts loose, lubed with penetrating oil, tried heat, not working. These don't have sleeves, just jam nuts that butt against the outer tres. Wrench flats on the inners tre's are starting to round over. Need the truck done today so I can get to work tomorrow. Don't want to thread the outers up to the nuts and have the alignment be way off (dropping it off for alignment tomorrow morning before work, 15 mile trip). Any suggestions other than drinking bleach or posting Tuesday?
