The frame has alot of holes in the sides and ends are open, i've never heard of a frame going bad like the old Jeeps did. I bought frame plugs to cover the holes on the outsides of the frame to keep stuff from getting into the inside.
Thanks for the quick reply.I spent a lot of time under my tj when I first got it cutting and welding the rotten areas. I was hoping There were holes in the jk frames for the water to escape. I had to drill holes in my repaired areas for drainage.
