my rear axle bolt has a 5/16 allen on one side, and a 15/16 hex nut on the other. the bolt is frozen and i stripped the allen side trying to get it off. ive tried heating it, beco-lube, penetrating oil, nothing seems to be working. im ording a new axle bolt tomorrow, but i still have to get the old one off. i havent tried yet, but i would think cutting with a hacksaw, or sawzaw with a metal blade would be out of the question seeing as how its hardened steel. and cutting the hex nut off wouldnt be the best either because its a grade 8 nut. any suggestions?
