Tearing the front clip off for all restoration of engine compartment (cab back is done) and I stumble across this mess.
Wheel Tire Automotive tire Motor vehicle Wood

Why would one side rot out like that and nowhere else on the frame?
Gonna remove engine and tranny and keep going. This 90 Silverado is gonna be my work truck/driver while I rebuild the engine in my 96 Silverado.

WOW
I wonder what my 90 GMC looks like
From what I gather, it's a known problem just on the driver side. To bad the 'known' oil cooler leak didn't happen in that area.
So, I'm going to take the steering box off and see how far until I hit good metal to see if I can weld a channel patch. I'm more worried about the steering gear mount than the bumper and core support mounts which can be purchased aftermarket.
The 96 looks great, not even surface rust.

I wouldn't spend a dime on that frame...It's too far gone.😱 Time to start to get a good used replacement frame and transfer all the truck's components on it.
Good luck,

I may not. But with all the work I've put into the truck I've got to give it a try.
I'll know what I'm gonna do when I pull the power train.

my kid has repaired more than one cracked Chevy frame at the steering box. I;m not the pro, but that looks rather FUBAR to me. Need a chunck of another frame.

Makes the 64 Elky frame he is about to repair look near mint! It also requires two chuncks from another.
If I get into it and I find good metal to weld to, great. If not it's ok, I'll just put the tranny (700r4-K case newly rebuilt with 0 miles) in the Monte Carlo (1970).
I've rebuilt the rear end on this truck with new Richmond 3:73's and stuffed a new crate engine in that has 28k on it, stripped and coated the frame, underbody, and fuel tank, new shocks, new leaf spring mounts, fuel pump and lines, etc....
Oh well. We'll see.....

Oh trust me, I'm not spending a dime on anything at the moment. Right now I'm doing everything that won't cost a penny.
I had purchased and new pass. door that is installed, two new fenders, rockers, cab corners, rear outer wheel wells, and wheel arch patches. Everything is on hold until I pull the power train and inspect this issue.

Those photos make me so glad I left the rust belt many years ago. Good luck with your project.
Yep, Ohio.
I think the car that crushed me the most was a 2001 Oldsmobile Intrigue that I had "rust proofed" that prematurely rusted. It was the first brand new car we ever had. My wife loved driving it. If I ever have a new car again, I will rust proof it myself.

Rust proof that’s funny rust resistant maybe but proof never going to happen, rust will be the end of all these vehicles every last one of them. It’s just a matter of time.
I don't know, eliminate oxygen and water and iron can't oxidize. It will at the very least outlive the human lifespan.
You should see the underbody of my Monte Carlo. I'd like to see a properly prepped frame with epoxy 150 years from now.

The ‘88-‘00 trucks are still going into the pick a parts down here, although not in the numbers once seen. Most are perfect underneath.

There's 8 of them in the local pull-a-part.

You can probably "fix" it but the rest of the frame isn't far behind.
The rest of the frame has been treated with chassis saver. It's what ODOT uses on the plow vehicles.
