Attaching Steel/SS to Aluminum - Eye Opener
Just read a post from GNTY (Thanks!) that references a Ford Report on watching your attachments to their aluminum:
https://www.fleet.ford.com/truckbbas/non-html/Q-222.pdf
as part of a catalog that further discusses the topic here:
http://issuu.com/truckhardware/docs/..._catalog_issue
See the pictures on page 2 of the catalog. Daaamn.... Watch those aftermarket accessories.
Despite all that, I did a quick look at the galvanic series to see if these two are at opposite ends of the series here:
http://corrosion-doctors.org/Definit...nic-series.htm
They are not far apart?!! In fact it appears they are very close to each other. (Not sure which grade of Aluminum though). On the other hand, there are some stainless steels at the opposite end. They appear problematic. But maybe someone can explain all this better.
But, I just wanted to raise the awareness of this. I knew it could be an issue, just didn't know how much of an issue.

Galvanic corrosion is a self created problem. The simple thing to remember is don't mix steel and aluminum. For example, don't grab those sheet metal screws to put your autozone mud flaps on. Same with bed boxes or whatever do-dad you feel the need to stack on your ride. Ford spent a great deal of money training ther collision techs and required certified shops to buy dedicated (Aluminum only) tools and build special clean rooms for doing collision repair on the new F150. All of that because contaminated tools and steel dust could cause galvanic corrosion post-repair.

I've been concerned about this very thing.
Something as simple as tinting windows could find a stainless screw used by accident instead of the aluminum one that came with it.
What about the clamps for tonneau covers? Are they shipping with aluminum clamps?
The little things like mudflaps, and wheel well liners, if steal is used, could pose significant corrosion, especially with the salt and water from the elements.
It's stuff like this that keeps me up at night, lol

Ford didn't pay for this. Each collision shop and dealership foot the bill.
