Frame Rust: Salvageable?

To start, I know this is terrible rust and I should not have let it get this bad. Please no bashing.

Has anyone ever had frame rust this bad and been able to repair it? I've been told a few different things: swap entire frame, cut and replace rear half, patch and reinforce. Suggestions?

Most concerning is where these pics are taken. These are driver and passenger side leaf spring mounts, lot of stress here and needs attention.

 

Is the entire frame this way? There's a company that sells freshly made sections of the frame. Can possibly make a whole new frame from it.

 

This is the only section this bad, there is some rust spreading up towards the engine. Do you have a link?

 

Oh god, put it out of its misery.

Personally I wouldn’t bother with patching. I would buy a new frame from out in the West and transfer everything over.

 

With rust that bad I would say find a replacement frame. By the time you start patching you will most likely end up replacing so much that a new frame would be cheaper/easier. I see them regularly on Craigslist and Facebook marketplace in my area.

 

If this is the only section bad weld patches in common problem areas and the places with holes, invest in por 15 and Eastwood internal frame coating. Do prep work extremely well too. If you do this it can be saved. Lots of people are too afraid of rust but it can be fought

 

This guy is in Banner Elk, NC his was stolen and they rolled it. It has had the frame replaced. I got a price from him for the whole truck minus the flat bed and it was a good price.

There is some places here that you can get a clean frame for less than $500 ONe guy was selling a 4x4 rolling frame minus the rear axle, but included entire front suspension, brake lines flue lines wiring and all for $500

What I did was used these as I had time and afford https://www.autorust.com/product-category/toyota/tacoma-xtracab-4wd/
It worked and it worked well. I kept finding more and had to do another section, and another and another until now I have a new frame basically caped over my old one.

By the time I took the bed off I had this great idea to cut the back off and weld a new rear section on and used the old frame to box it in. WOW dont do that. Boxing the frame is one thing, but cutting one and re-welding is another. Now befor I get bashed, I used 1/4 plate on the inside, stair stepped it, and used the safe-t-caps over all those welds too. its stronger than it was new and heavier with all the extra steel. The problem is getting it perfectly aligned. just a little bit of welding is enough heat to throw it all out of alignment again. I had measurements, cross measurements and a ton of jigs I made and come along, straps, cables and chains to hold everything perfectly in place. I did it, but WOW that was way to much work. Im good at welding but that weekend project turned into over a month of work, after work and 3 day weekends working day break to 11pm every night.

If I had it to do over again I would have done a frame swap. It is not nearly as bad as it sounds. there are some great videos on how people do it without pulling the engine.

 

The rest did not look bad at all. This is what itlooked like after a ball pen hammer. The truth is underneath.
Also these where taken befor the welding was complete

 

Here you can see where the po tried to repair it. I ended up cuttng all that junk out.

 

It all depends on your skill set for some replacing might be easier .

Having done a few frame stretches over the years building a new frame or rear section for me is not that difficult

Nothing is never so far gone it can`t be saved if it is cost effective that is the question.

Having on more then one time put $15,000.00 or more into a vehicle worth less then $2500.00 I can`t talk about cost effective.
