extensive unibody frame rail rot!!!!

I am posting some pics of my 93 zj 4.0L which is about to get a long arm treatment that has extensive frame rail rot right where before the lower rear controle arm mounts. since this kit requiers me to cut these mounts off in doing so it will allow me to have easyer acsess to the frame rail for patching purposes. any help would be gereatly appreciated i am a diy kinda guy and am looking to make the repair myself.

That's nasty. Looks like it's been exposed to salt water. You could try welding in steel plate to reinforce it, but I'll bet you'll have to cut it way back to find solid metal. Rust is always worse than it looks.

If I saw that, I'd be looking in the paper for another ZJ.

Start cutting until you get to clean steel.
Once you hit clean steel weld plate in there.

Unless you cut the rust away its going to rust again. Look in the paper for another jeep .

Just fine another 4.0 ZJ without the rot and rust. They aren't expensive. Then swap all your stuff over and keep the other one for a parts vehicle.

Thanks for advise...but I think I'm gonna keep this jeep. I knew I had to cut out the rust I was wondering if the gage of steel used matters.... Like is going heavy gonna help or should try to match it to the stock

GOing thicker than stock does nothing...going thinner is bad, same thickness makes welding alot less stressfull.


But my 89 SJ Grand Wagoneer had rust like that....I sold it for scrap. Once you get bad rot like that its hard to get rid of.
