Like many others, the frame at the rear spring shackles was rusted through on my YJ. Since I don't know how to weld well at all, I took the frame to a professional welder. The more he worked on the frame, the more rust holes and damage he found. The result was excellent patchwork and I was very pleased with everything.

Perhaps you could patch the damaged area and not find more damage. Most likely you will find more rust and rot. Good luck with your project!
