Alright, on the topic of rusted door bolts. We got this 2005 TJ with 3 of the 4 nuts already snapped off of the door hinge bolts. In the attempt to remove the last one, it also snapped off. I've tried hammering the bottom of the bolt with the door open but it wouldn't break free. I've been soaking them in PB blaster for weeks now. Really don't want to have to jack them up. But that seems like it might be the last resort. Any tips?
