Hello. I just joined the forum and am very excited to learn more about my recent purchase — 2003 TJ Wrangler (Rubicon) jeep w/64k miles. Before I purchased it, I was well aware of the problems w/a boxed frame (which I believe is a design flaw) and how it is prone to rusting from the inside out. Would like to know if anyone on this forum has any options or recommendations on how to remove the rust from the inside of the frame. I've viewed a few YouTube videos and some owners have suggested using various tools (plumber auger w/chains) to remove the rust. But I think that is cumbersome and may not remove all the internal rust. Note — my jeep has some rust inside, but it is difficult to tell...there is also very little surface rust on the frame (i.e., nothing is rotting; and I can take care of the surface rust myself). The concern is how to deal w/inside rust. Thank you very much for allowing me to join this forum.
