I don't no what ford painted their rear axles with but I am having a heck of a time trying to remove the paint. I bought three different things to put on my heavy duty drill. Thought I was going to burn the drill up and only have a little of one side done. Not really even done just started. The paint just doesn't want to come off. This can't be regular paint? I tried my grinder. Don't like what that might do. I think I am going to try and find some one local that might be able to sand blast all my suspension parts then I can sand them and repaint them. Either that or I might try using stripper on them?
