I'm just looking to calm things down here, so just take this as another bit of analysis. I was cleaning my wheels the other day, and I also saw rust quite easily on the front end suspension parts visible in the front wheel well (as I recall it). As this thread gains age, I think you will have a number of posters familiar with car construction and metals confirm these points. Some metals are well known to have surface rust, but not rapid structural damage. Surface rust in fact, in specific cases, does creat a protective coat. Now I'm NOT going to claim that fact for these bolts and hardware, because I DON'T know that for certain. But I do know that some building materials have planned-for controlled rust, and I am quite certain that the rust that is being complained about here will not reach the point to require part replacement. In other words, the rust is not because of carelessness by Dodge, it is because, by judgment, it is not worth coating or painting certain hardware. There is some metal that will literally rust when left out overnight, but it does not predict rust through. If you know metals well and want to claim that Dodge used cheaper metals, then have at it and I'll listen. The rust we are talking about is cosmetic only, and as someone mentioned earlier, Dodge is not in the business of building show cars. It is debatable even whether the metals used may be stronger overall. It was know for years that Asian fasteners were low quality and inferior (see Jack Anderson columns from a few decades ago). It's my theory that you see cosmetic surface because the materials are actually stronger structurally than some cheap alternate materials that would not show the rust.
Yes, I have had many cars over the years, some 40 to 50 years old when I owned them. As long as the rust is not showing up on body parts, I would recommend less worry about this. If you do feel like correcting it, I would recommend learning about metal properties first, and the reason you are seeing this on certain parts. By the way, exhaust systems rust from the inside out in general, and surface rust on exhaust systems is superficial in most cases, or at least secondary to the rust through from inside.
