Meaning, quite literally, aluminum against iron plus water/water and salt creates current flow that causes the aluminum to corrode. Which is why the wheels pit on the inside -- it's the aluminum's equivalent of rust. The clearance between the hub and the inside of the wheels is unusually tight on the Focus; when it fills up with corrosion it welds the hub and wheel together.
Silver anti-seize is the best to use -- it won't wash away or migrate like grease or oil does.

Excellent explanation, but....can we use that current to charge a dead battery? :lol: :lol:
