I suspect newer road treatments like the stuff Tommy mentioned. The call it brine up here. Anytime before a storm they go out with these tanker trucks and you see the lines on the road where the streams of this juice are laid. I don't think the stuff is very good for any metal.

I would love for my trucks to get a hard lune and strap overhaul for free. I'm just not convinced that GM ownes the problem or solution. The fact is, I own the 2001 truck and the 2000 Yukon and they have been really great trucks with a low cost of ownership. Other than this one issue- the trucks have exceeded all expectations.
