So I was kind of happy with my findings the other day, then upset yesterday. Just a topsy turvy emotional roller coaster.
I will state that if I would have known the true condition of this body I would have never bought this Jeep. I am also going to state that I am not going to spend a lot of money to have this tub repaired and repainted by someone else. It might look good for a little while, but it has some issues. I am not exactly right in the head so i am going to try to salvage it myself. And I would never resell it to someone else and pretend that it is just all hunky dory. It is not, probably never will be. But, I'll give it a whirl, unless my findings go completely down hill once I really dig into it.
So, the rear "box beam", the part that the very rear body mounts rest under that spans across the rear/under the tail gate opening, pretty F'd on the driver side, passenger not better. I was going to try to repair it with some heavy gauge sheet metal, but:
This is the driver side back corner. It rests against this structural piece. Hard to see in the picture, but you should see slight indentations from the OEM spot welds. I have bulges, meaning that the back side of this corner piece is rusting.
This is the driver side, from under the Jeep, forward side of this "box beam":
So, game plan here: grind off the paint, drill out all the spot welds, install a new "box beam". Classic Enterprises sells this part, I believe they call it a "tailgate end support". I will either re-spot weld it and/or use structural panel adhesive here.
Most of the rest of the underbody looks like this:
Solid metal covered in surface rust with a layer of OEM paint/undercoat/thin metal layer peeling off. Salvageable.
All of the other major floor pan structural pieces are still solid, just look like crap due to surface rust/peeling paint/peeling undercoat.
The thing that concerns me, and there really is no way to repair it: some of the seams where say the floorboard flange is pressed up against say the rocker panel. There is some corrosion at these joints.
This is IIRC passenger side rocker panel to passenger side outer floor board flange joint:
So, I can grind it, wire brush it, beat on it, vibrate it, and get some/most of the rust out. Then try to brush in some really oily/creepy rusty metal primer. That is all I can do short of replacing every body panel/floor board. Now, as bad as this look, I said "F" it yesterday, grabbed both lower rocker panels and tried to rip them off this flange. There was a little deflection, but the original weld joints are still strong and I did not crease the metal.
On the outer rocker panel, this is passenger side, you can see where some rust is starting to bubble the paint out at this joint.
Pretty sure there was body filler work here, too, at some point in time. I plan on grinding all the paint off at these flange/rocker seams and see how bad it is. Still feels solid, but I need to try to slow down/stop this rust. Probably pee-peeing against the wind but what the hell.
This is the passenger side toe support/floorboard/bulkhead area, where the front fender bolts on. Solid, just looks like shit:
Running my fingers along the inside bottom edge of the passenger side rocker panel, note debris left on top of step!!
Passenger side rocker where floorboard angles upward above the cubby hole picture I showed two pictures up:
Hard to see, but just OEM spot weld marks following this joint.
So, I plan on doing a bunch of work to this tub and it might all be for not. Might as well give it a try before I do a tub swap.
One other note: as bad as this looks, amazingly this Jeep feels really solid. No rattles, groans, creeks, other odd body noises/issues.
Figure I'll at least try to preserve what I have for as long as possible. If I was trying to make a super nice show Jeep or this was my only Jeep or trying to build this thing once, I would just shit can this body. And I might still have to do this, won't really know until i get into it.
