Hey Guys ....

We've had some hard hard rains here the last few days, so the car has sat (I don't really drive the CTS-V in the rain, we stick to our Jeep). Anyways, went out yesterday and noticed surface rust on ALL 4 wheel hubs? See Pictures ... Has anyone else ever had this happen to their CTS or -V ? Very strange, I've never had this happen to any other vehicle ....

Is there a product I can use to fully remove it? And would it be best to pain the hubs with a Rust Proof paint/adhesive?

Here are some pics (coming in 3 more posts -- I need to have 5 to post links/pictures)

Happens to my car too. Just drive it, it goes away after the first brake application. Happens on cars other than the V as well.

I'm not talking about the rotor ...

Look at the hub ... The hub won't rub off like the rotors - My rotors have rusted on every single car I've owned :) haha

The hub will develop a complete coat of surface rust if left to its own devices. (Look around at other cars). Some paint them, some try to keep them dry. Yours looks like a very early case that will clean up with light steel wool and be good as new. If you occassionally wipe them with WD-40 or something similar after exposure to water, you can generally keep them rust free. (you need, of course, to keep any protectant of the rotor surface...)

Yes good advise from Dave Nichols. One option would be to paint with a high temp paint then apply some sort of protectant.

I am considering doing this myself.

well ...

Just went at it with Steel Wool, a cup of water, and some WD40 ... Got all the rust off, but underneathe, it had already turned a blacking/gray color. Atleast its better than the rust color!

I'm probably going to paint with a high temp engine enamel, and if there is even a *chance* of rain, keep her garaged.

Thanks for the suggestion David & cbl .... what type of protectant would you use over the paint?

My bad. The rotor rust comes up on such a regular basis in this forum that I only half-looked. :D

High-temp enamel is your answer and I've thought about doing the same to mine.

you could have them zinc coated and/or buy zinc coated rotors. Painting will work for the Hubs, but the veins will continue to rust into nothing. Zinc will take care of *all* of that. I can't believe they're not zinc plated from the factory.. my 10 year old B5 S4 had the factory rear rotors and 0 rust .

I had the same issue and just painted them like others have said. No big deal.

Those of you that have rust on your rotor hubs: Do you use any kind of wheel cleaner? I thought I read a while back that some wheel cleaners will take the coating off the hub which then allows rust. I haven't had the rotor hats rust on either the V1 or V2, or my wife's car either.

My brake rotor surfaces rust like above when they get rained on or I wash the car, but after a few stops they are clean.

I also had discoloration of hubs from certain wheel cleaners. On GM light grey hubs (TBSS, C5, C6)they stained turned hubs dark grey/balck almost. I stopped using spray on wheel cleaners.

I switched to Baer Zinc Coated Eridispeed rotors on my C5Z06 and C6-Z51/vert, and had no problems with or without any claeaners.
To be 100% sure, ZINC plate them.

You can see how it looks here with the z06 front rim.

My car only had 400 miles on her when I noticed the rusting hats ... No wheel cleaner ever ...

My hubs have rusted pretty good. I took it to dealer and was told this is normal. Nothing could be done. I hate these rusty hubs so much (so ugly) so I searched the forum. Found this post, but I don't have the equipment, time, or frankly the ability to do this myself. I'd need to pay someone to do it for me. That said, I went to a local body shop but they wouldn't want to paint my rotors. Should I take it back to the dealer or the body shop and bring a pack of SOS pads and a copy of this thread? I undertand why someone wouldn't want to paint my rotors (liability) but I feel like this is an issue that dealers and body shops would see on a regular basis, no? Suggestions would be appreciated. I'm going back to dealer to have my clicking wheels addressed again, so it wouldn't be a special trip. Thanks in advance.

I would sand them, steel wool them, get the rust off... Then apply some Armor All Wheel Protectant or something similar. It's just a temporary fix, as this might need to be repeated every year or so.

As for wheel cleaners, don't use the heavy acid based ones. Use P21S or just a simple multi-purpose cleaner for the wheels. You don't need anything strong. The acid ones may contribute to rust on the hub.

where do you live? I'm @ 4,000 miles, and I have 0 rust. However, I can say they they're definitally *not* coated, Zinc is a visually shiny metal. I'm sure considering the amount of solvents in wheel-cleaner though it doesn't slow the process of oxidation however.
