Cab corners, fu3k.

[kennythewelder]

Well I have been looking at these 3 little bubbles for several months now. Well after picking at them tonight, here is what Ive got. Im going to look in there with a camera. I will have to get the owner to bring his so I can see in there. I think I got all of the rust, but I will look inside to see. If I got it all, I will fill weld the holes. I really dont want to change the whole corner if I dont have to. $hit, I dint want to have to do this, oh well, there no turning back now. I go some navel jelly in there for now.

That sucks and on such a nice truck.

And I'm having to deal with almost same thing on my truck. Compeletely rust free except for cab corner from rear window leaking for years from PO

Dang. at least you caught it before it gets worse

Well, I cut some small plugs out of scrap metal. I welded them in place, ground down the welds and primed for now. I will still need to use a body filler, sand, and sand , and sand, then prime and sand then paint.

Are there drains in the corners?

Kind of surprised you had rust there given our climate.

Rite, yea there are drains, and mine were not clogged up at all. What really baffles me is why that high up. At the bottom of the cab corner I could under stand, but just a little under the seam???. The only thing I can figure is a while back, I had water on my 3ed door, door handle. Like maybe it rained in there. I have been watching it, and dont see that again, so IDK maybe the door wasnt shut rite with all the rain it just seeped in, IDK. Maybe also, because it rusted from the inside out, maybe there was no or almost no paint there, on the inside, so it didn't take a lot to make the metal rust. I think I will make a hole in the back of the panel with a hole saw so I can treat the new repair. Before I repaired it, I drenched it on the inside with Ospho. I know that stuff works. I looked in there with the a cable camera we have at work. Before I Osphoed it, I could see some surface rust. After the Ospho, it was all gone. I didn't see any big flaking spots. Looks like I got all of that out.

I wish that was the only rust issue I had to worry about, lol

-Same here. Current truck doesn't even really have cab corners at this time.

I'd post some pics of the rust on my Suburban to make you feel better, but it makes me sad to look at it. There's a nearly 3' chunk of metal under the rear driver's side door that's just gone.

These spots were something left unattended at the factory. They all start in the same place, mine did too. I wonder if you could fill that entire corner with spray foam after the repair?
