Rust on cv housing area?

[navydave]

Not sure what you call it but on either side of the manual transmission there are two round cylindrical parts that the axle shafts connects to, that go onto the transmission itself. The car is 3 months old. (Purchased July this year). Anyone know what these are called? Anyways, when I did my first oil change I noticed a light coating of rust on them on both sides. The factory part stickers were still on them and they have a light to medium coat of rust. I kinda freaked out and sprayed them with some marhyde undercoating. Dont ask me why. Now I am thinking I should have showed it to the dealer. Is that something that they would fix? Or am I probably screwed now that I covered most of it up with marhyde. I could kinda scrape it off I guess, and I dont think I covered the top parts of them since I was spraying from underneath. UPDATE: I think its called an inner cv joint housing or inner driver?

Those are pretty hefty steel or cast iron. i would not worry about it. Your doors will rust out long before the Inner CV Joint Housings cause a problem.

The coatings were probably cut back for cost savings. I would not worry about it since it is probably surface rust. Rust cannot really cling to moving parts, hence if it is the axle shafts or CV parts they spin too fast while driving. The parts probably had no coating and were rusting sitting on the shelf and before they were even put on your car. Lots of car manf are leaving off coatings to save money. Look at your exhaust in a couple of years, I think we are going back to muffler replacements! I have noticed this on just about every Chrysler vehicle I work on...

while i'm not sure they're using it on automotive applications, there is a grade of steel that will actually form a light layer of rust to protect it from rusting further. used for those large power line towers in many areas.i think i saw the same 'rusting' issue on my vibe during an oil change and the way it was rusted reminded me of this 'special rust grade'.
