Very rusty problem
 

Hey guys this is from my 2000 jeep Cherokee xj sport and it is the rear right frame rail that's rusted right through. I was wondering what you guys would do to unf*ck this situation. Literally anything helps, thanks guys.

Oooo...:icon_eek: That's a no good. I would see how far the cancer has spread and determine if you're (or pay somebody) prepared to cut out/repair the damage. Seem like you have more than just that trouble spot from the looks in the background.

Might be better off setting that one to pasture for parts...

Shoot that is how ALL Ohio Cherokees are. Just cut it out and weld in a patch panel. Its easier and safer to drop the tank, and rear axle to get it all out of the way.

I would then go ham with some rust converter on the underbelly there.

Mine had a hole in that exact same spot, I would just cut it out and weld in a patch panel. You could always get a set of rear frame stiffeners for extra strength. Unfortunately, most of my floor pans were also gone or I would have just patched mine.
