Default Re: Rear Diff Plug HELP

Try the vice grip first. I would avoid drilling the plug because of introducing chips into the housing. If the vice grips fail, I would grind off what is left and then weld a nut onto the plug, as Randall said. Do the weld in steps so as to not heat the housing too much. The heat from the welding should help with the removing the plug.

My plug on my differential has the square hole recessed in the plug and is a much stronger design. Buy a new plug from one of the usual vendors.
