I've got some weird noises coming out of the front of the Cobalt now. Anything above 35 MPH, and my wife describes it as a cross between a lawnmore and an RC airplane. I'm not sure what to make of it. I wonder if it's some sort of bearing growl... Anyone heard of this? Is there some technical service bulliten out there on it?
Some more background. I recently did the front struts. Also there's been this rattling sound going over potholes--struts really didn't fix it....
But this noise over 35 MPH has me REALLY concerned. What could it be?
Edit:
* It does it with or without my foot on the gas.
* It doesn't seem to have anything to do with braking or turning
* The noise changes slightly in pitch when you are going faster--I liken it holding cards to a fan blade at different fan speeds...
