Severely rusty frame. My 4runner only has a little over 114k miles on it. It shouldn't have anywhere near the amount of rust on the frame. It's everywhere and flakes off to the touch.

My vehicle has very little rust except for the rear differential. Large flakes of rust have formed. The differential recently began leaking. After searching online I see this is a common problem with 4runners.

Extreme rust on my 4runner's frame. Can be seen easily from in and outside of vehicle. I have many pictures to document. The recall on Toyota tacoma and tundra should be expanded to include 96-02 Toyota 4runner.
