Rust. How much of a concern?

Hello! First time posting in here. Question for all: how concerning is this rust on the body mount? The rust is similar on the other side as well. Is this a big concern? Can it be fixed? Any advice and/or recommendations would be greatly appreciated.

Thanks!

 

I’d be concerned. Won’t know until you strip away the cancer and see what’s left. May need a reinforcement. I suggest www.autorust.com to get one.

 

That's pretty bad, it looks like the steel is delaminating and the cab mount bucket is detached or detaching from the framerail (see red outline below). AutoRust does make repair panels for the cab mount, but it doesn't include the 2nd rabbit-ear shaped piece (see yellow outline below). The cab mount has the actual bucket itself, and the little rabbit ear piece.

If this is what the cab mounts look like, I'd really hate to see what the more-problematic trouble areas look like. If the rabbit-ear piece here has a hole rusted through it, I can only imagine what it looks like above the tire carrier, where the X-shaped stiffener for the tire carrier meets the frame, where the framerails are beefed up with a stiffener near the rear of the cab, and the sections of framerail above where the leaf spring mounts.

Is this a new truck for you? Hopefully not a new purchase, or if it is a new purchase, hopefully the seller disclosed the damage. This is a concerning amount of rust.

 

Actually, looking at this again, someone surely musta knew about this because it's been shittily repaired before. See in orange here, someone welded a plate on the bottom. And outlined in pink, I clearly see the cab mount bucket is separating from the rail. And honestly, I don't even know if you could actually weld anything back onto the steel below it, because it's so badly delaminating, I don't think even a seasoned professional could get clean penetration into the rail w/o a shitload of work. By the time you got to clean metal, I wouldn't expect it to be thick enough to handle the weight above it.

Thanks for the replies. This is a new purchase, I have a 2011 4Runner for primary use. The seller did not disclose the rust to be problematic like it seems to be. I should have inspected it much more thorough than what I obviously did.

I don’t mind spending some money to fix these issues, but it sounds like it may be unfixable? Unsure of what that expected cost would be as well.

Here are some additional photos of it helps any. Thanks again.

 

I mean, the long portions of the rails don't look too bad, but those usually aren't the problem, and often get washed off. Problem spots are typically where treated road grime can get inside the framerail, or pool at a welded joint joint, and/or where pieces are riveted together. The fact someone actually took time to weld an already-too-thin-to-do-jack-shit plate onto the frame, shittily at that, is telling to me, someone knew there were issues in that spot.

Around here, that's a $3k-4k truck. It's an '06 and thus isn't eligible for recall. I take it you've already checked out this thread?

 

Oh, and it could be worse. It could look like this.

When I need inspiration to give to rusty framed folks, this is where I point them - @N84434 really did a great job on his truck, and you can see some other potential problem spots to check out.

Thanks for all of the info here I appreciate it.
