Ditto what Fox said. I will just add that whatever you do to get the drums loose, do it carefully. Those drums for the 1 Ton are basically gone from everywhere. Extremely hard to find if you have to get another. Take your time with them and you should be able to get them off the truck. I struggled with my 1 ton some years ago like you are. Now I make it a habit to check them twice a year to make sure I can get the drum off when I need to. Good luck with your truck! Tom
