Rust R Us ?

[grampa bob]

Changing the oil on my 2004 Denali (6775 miles). Noticed CV s ( Boots excepted) Driveshafts- Shocks(Front) Steering Knuckles all covered in RUST. Anybody else notice this or am I missing some underbody corrosion protection?
Could not locate a TSB addressing this condition.
Any comment Yea or nay appreciated.

Thanks
Bob

Is it just surface rust? If so, it should be alright. If the parts are actually starting to rot away...then you've got some problems.

I think the rust proofing stuff is optional, but I could definatly be wrong. Maybe someone else will know.

Thanks for the response. It is just surface rust, but I have a 15 year old Trooper that looks better underneath than my almost new Denali. Just another example of GM wanting premium prices, while being penny wise & pound foolish.
