Title says it all. 4 days of penetrating grease, giant socket set with cheater bar. I started almost to lift the pup. Next was the impact driver, nothing, the bolt sat there , i sware it laughed. So , the question is, do i try to heat it up next? Alternates to try? Maybe drill it out and a hacksaw to cut out the rest? Or live with it untill it craps out. Probubly last a few years, i can always get the portable propane hot water heater. Ideas?
