Some of you guys really don't care if your frame has rust on it? It bugs the heck out of me, especially since it is on pretty much every weld under the 4runner. Sure it is fine now, but if i just leave it, it will just keep getting worse. If toyota would have just spent a few more bucks and put another coat on there or bothered completely covering it, we wouldn't be having so many frame rust issues. Nobody should be seeing rust on their 3 month old vehicle, and nobody should be ok with it, just accepting toyotas cheapness and lazyness.
I would say having a rusting frame after 3 months, in an environment that doesn't normally produce much rust, is a serious issue, and shouldn't be compared to that stupid sunvisor thread...
Jeez I didn't think you were serious! The rust on my frame does not cause me any concern. I have owned BOF vehicles for many years and every single one of them rusts. If you want no rust underneath then get a unibody vehicle. They are made with HSLA steel that inhibits rust. Our frames and suspension components are made with mild steel and will rust at the first nick. Is this your first BOF vehicle? They are heavy duty but will rust. You need to worry if you start getting deep pitting. That little bit in your pictures is no big deal. I had my SR5 two winters (lots of salt) and even though some of the components were rusted none were abnormally so. You could get it painted but you run the risk of the paint chipping or cracking, which will cause pockets and trap moisture causing it to rust worse. Toyota frames and suspension are no different than any other vehicle (Dodge, GM, Ford, Nissan and my 1984 4Runner) with respect to rust that I have owned. I am confident these vehicles will be fine 15 years from now in respect to rust on the frame. OCD can be treated.
