Just wanted to remind that when Toyotas first came over here, they rusted badly.
Examples like the Corolla, pickup truck beds back in day.
I guess I'm lucky that my 98 4Runner is okay but it originally came from Texas-
I am well aware of how they were when they came over as I have own Toyotas a very long time. I had those pickup trucks back in the day and you know those beds were made in long beach CA they use recycled junk steel in them. How do I know this.. Well I redid a 1983 Toyota 4X4 and saw the Original bed sticker on its bed said Made in USA
Japan sent those trucks over unfinished so the tarrifs on them wouldn't be as high.
Japan used a lot of recycled steel in the 1970s and 1980s until they refined the steel process
All the 1970s and 1980s vehicles were pretty much rust out fast. Especially in the Rust belt.
My point was did we have recalls then on Rust?? The answer is no.
By the 1990's the steel was much more refined and they went into the anti-corrosion coated panels.
For Example:
If you look at a collision repair manual for the 3rd gen. It will even show you the steel panels that have the extra anti corrosion coatings on them. That is what really ended the fast rot of the steel.
Its not like these frames rot out in 5, 10 years it was always like 15, 20 years before they are rotted. That was the same now as it was in the 1970s and 1980s. What really has changed.
The answer is the improperly made frames by Dana Corp. That mfg messed up and that is the only reason that we have the Tocuma and Tundra,etc Frame and Truck Recalls.
I had a 1998 Tocuma SR5 that was bought back by Toyota and I have a 09 Tocuma that has an extended Frame Warranty over that problem. Along with owning over 20 Toyota vehicles thus far.
