I have these stock step bars. The ends are terribly rusty. I want to get rid of it. Turns out I had to unbolt the front to install new fenders. The back is an issue. I have every size wrench there is. I jest couldn't get a good bite. I don't have access to a torch.
I'll try the kroil. Gonna have to jack up the jeep and remove the back wheels to get to these. Just haven't had the time. Hopefully I can work on this over the next week.
