Severe Frame Rust is Not Acceptable

I think it all depends on your dedication to the vehicle and your fabrication skills. I have seen a complete frame rebuild on a truck that had sentimental value and a frame that consisted of more mud and debris than actual steel.

Thats just beating a dead horse though, if you work out fabricators time at $75 an hour i think you will find its cheaper to put a new frame on.
 
I love toyota but they have problems with their frames ! If you want proof of that I will post pics of the stacks of frames behind my local dealership from Tacoma's and tundras ! And don't try to tell me it's a isolated problem .

The affected Tacoma's and Tundra's were made in the USA, and had frames that were supplied by Dana Corporation. There was a recall because they didn't meet Toyota's specs.

The 4Runner has always been made in Japan, by Toyota.

I have personally seen vehicles from all of the manufacturers, that have rusted severely to the point that they are ready for the junkyard, in less than ten years.

What they all had in common, is that the owners neglected to keep the salt off of them. Either they didn't make the effort to remove the salt on a regular basis, or they didn't personally confirm (or contract with someone to specifically confirm) that their efforts were effective.

Toyota's warranty for rust-through of the sheet metal is 5 years. If a frame were to rust to the point of failure within 5 years, they probably would be willing to replace it.

The bottom line is if you live in an area where accelerated corrosion is an issue, you had better take extra steps to ensure the longevity of your vehicle (any vehicle), or it will rust away sooner than you would like.
 
My recent 4runner pre-purchase burnt me bad due to no vin check so wasted a whole day off work driving to st louis to buy a perfect 99 limited 4hr drive to get out and look under truck to see horrible rot,pissed me off dealer wouldnt send pictures of frame to me,too busy he said.told him to shove it and returned home,did a auto check on that one and sure enough sold at auction from CHICAGO (salt rot capitol),ended up finding one from louisville KY and had owner send me GOOD frame photos,save yourself the pain and research a purchase of these.As for OP I kinda side with him,have had many 79 f350 4x4 with open "c" channel frames that lived in salt-hell illinois that rotted off only outer layer,still sound,toys and there full box frame and steel type just seem to beg to die in salty areas,sooo jealous of owners from south and west,the super rust free frames are to die for!Also love Illinois for a superb reaction to snow flurries,salt her heavy boys,not everyone has a 4runner that will go every where!!

Dead Runner, plain and simple....... COB is the best moderator ever and was nice enough to remove the stupid things that I said earlier. Isn't he the best? Haha, just about any other moderator would have blocked me!

We are so fortunate to have such a wonderful forum.

Sorry, but here's where you lost me. There's no way that rust just showed up instantly. Even if it's from the inside. If you were as diligent as you said and checked the frame regularly, then you would have seen signs that rust may be an issue. I would like to see some pics of your rear diff housing. I bet it showed signs of rust as well.

It does though, I have seen frames that look solid with original paint on some sections and you can effortlessly put a screwdriver through it. IMO the 4runner frames should have the same recall as the taco's do, it just took a little longer for the problems to arise in high numbers.
 
I think that the frames on the 4Runners aren't as good as some other comparable vehicles. Hell I have a 91 Honda Accord that has been in Indiana its whole life. I never wash it and it has 200k miles on it. The underbody on that car is like new. All of the parts on that car look better than my 4Runner. Also, I do not see how taking your truck to an automatic car wash or even a pay and spray will help with the inside of the frame unless you specifically spray inside the frame rails. I do agree that people should do more preventative maintenance on their vehicles, however, a car manufacturer must realize that 90% of their target audience will not be like people on this forum. They will take their car in for oil changes and check engine lights and thats it.

that's awesome, larrylegend, but your 1991 Honda Accord is unibody, and totally different.

that's like comparing my 4runner to my space ship, which is made of imaginarium. It's from 2543 and has 34 light years on it, and has no rust! Toyota's should last longer!!
 
Dead Runner, plain and simple....... Quit being a douche! If you want to bad mouth the vehicles that we adorn, go somewhere else. This is NOT your forum!

i dont think he's being a douche , i think he's upset that his truck rotted away before 100k and i dont blame him .

i think someone from from florida that never experienced winters or salt and commenting on this thread is being more of a douche !

Before you cast stones at me, COB should come through and remove my rebuttal.

This was mine after 317k miles. I had it welded up and is stronger than it was new.

I can post pics tomorrow if anyone is interested. The rest of the frame, supports and undervody look great. It just the area next to the muffler....
 
they all seem to rot in the same place . mine was rotted in the same spot and the rest of the frame is in perfect condition.
 
Woodro, I feel the distance between us is not a reason for me to express humility. Thus, I will allow sir COB to reword my posts.

Keep talking woodro, its easy to talk big when your hidden behind your computer. In person you would get your ass kicked!

hahaha ! are you for real , you want to kick my ass through the internet ?

im not "hidden" behind my computer its called a forum you retard
 
Well seeing this is popping up in more than one thread, whats the preventative solution? Are there good ways to prevent rust on the frames for some of us who do not have it yet? Straight up paint, POR-15, Line X, old school undercoating, what is ideal?

I was also wondering if I do keep my 4runner forever and move back to a place it could rot, other than doing something to the frame, what about the underside of the bodypaint and inside fenders and rockers etc? My paint isnt bad, but has some sun fade on the roof and hood....I saw a nice looking old Yota Taco OD green in town, thing looks cool (to me), although it would make the 4runner look less appealing to most and not as "normal" OD green would be slick to me! haha

Sir that sounds like a threat, many of us have arguments on the forum, but it should never escalate to that. We are a community here, not a place to bash others (apperently that's literal for you).

Thats the problem, because these rot from the inside out, i am going through the same thing, as i am bringing a completley rust free truck from AZ to NY in a week and have to figure something out, washing it off won't prevent all of it. I think the only real solution is to get the hell out of the rust belt.

I guess I am fine for now....but am considering moving to Colorado or back east somewhere....Id love to keep the 4runner if I do, would be amazing hunting rig and light wheeling rig. Id rather do something now while its here and not rusting, then bring it somewhere and it starts rusting.
