I was at the dealer over the weekend with my dad test driving the new 6.7 and I was looking at the new exhaust system comparing it to mine, well when I looked at mine I noticed that my driveshaft was covered in RUST. Is this normal? My truck has 6000 miles on it. On a side note the driveshaft on the new 6.7 trucks are way bigger.

 

I think they all do that. It's surface rust that shouldn't get much worse. You won't get rid of it unless you sand it all down and paint the driveshaft, but I don't know if that would introduce other (balance) problems.

 

When I started looking in late 04, every truck I saw here in MA had alot of rust everywhere underneath. I looked under alot of them as I was comparing the 600's with the SO's.

I ended up buying in CT where undercarriages are black. Mine's still black even after two New England winters, although they were mild.

 

Thats perfectly norman on the drive shaft.

 

Who's Norman, and why is he on the drive shaft?

 

It was that way when I bought my '03 new. My first mod was day 1 - can of black on all metal surfaces under the truck (it's not just the drive shaft that is rusty).

 

Whoever this Norman is, he is perfectly though.
