Help! Mystery Nut!

This nut fell out of my 01 this morning. I started up the Jeep this morning and it fell out. It was laying under the skid plate, more rear than forward. I drove about fifteen or twenty miles and it drove fine. When I got to my dad's house, I crawled under and couldn't find anywhere that it could have fallen from. I think the nut is 1 1/2 in. It is bigger then 1 1/4 in, that was the biggest wrench in the garage here. As the pictures show, it's some kind of a stop-nut. So does anyone recognize it or have any ideas...? Thanks guys.

Some type of exhaust nut? Or maybe it got kicked up into your Jeep? Idk, doesn't look familiar.

edit: O2 bung?

Thanks a lot! I'll check that out. You might be right about it being kicked up from somewhere else. It looked a lot bigger than anything I have ever seen under the Wrang.

That was my first thought as well...

Hi all

The nut has an inner lip, more like the ones that hold fluid lines or sensor............

O2 bungs are welded into the pipe normally.

I don't think it came from your Jeep Tht looks like a nut that would be on something like a a/c line they do not come off unless the line is cut It was likely kicked up on the road.

I agree, a few weeks ago I replaced the clutch in my 06, so I had the skid plate off, tranny and tcase out, so I had a pretty good view of just about everything up and under there and it doesn't look like anything I remember seeing. But I did find about 5 pounds of dirt, sand and rocks on the inside of my skid plate, so I'd be willing to bet it wound up up there.

I just installed a long arm lift a few weeks back, so needless to say I've been under my Jeep a number of hours to install and go through and re tighten. I haven't seen any nut that resembles the one you have pictured. A case of a kicked up nut.

It looks galvanized, probably plumbing road kill. I just wonder if those are safety wire loops?

Thanks a lot guys. I thought (and hoped) it was foreign. It looked too big to be from the Jeep. I replaced the clutch twice back in Jan/Feb, and I wondered if it could be from that. But I guess not, thank God!
