Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

If it is in the right rear the only thing I can think of is the tire or wheel bearing. Just because the wheel bearing was replaced do not count it out for making noise. Parts these days anything is possible. Been down that road way too much with brand new parts out of the box bad or they do not last long and go bad again.

Glad you could get it fixed, that kind of problem can be tough. Please use 2CarPros anytime we are here to help.

Hi, we just went through his on a another car. It was the final drive carrier bearing inside the transmission, but to be sure please make me a short video of the noise and upload it here in your reply we have the capability. That way I will know for sure.

Cheers, Ken

When your driving it and the noise is apperant, try doing what they do in nascar to warm up there tires, moving back and forth, ( do it safely) does the pitch change or stay steady

if the pitch changes, its a bad bearing somewhere, if not its probally the tires

Thank you for the response. I tried the moving back and forth and thought there was a difference in the pitch but it was difficult to do a true testing. I had this checked out at a GM dealership and found in fact it was a bad wheel bearing. In retrospect, the wheel bearing went out at about 20,000 miles.

My experience with a 2006 Chevrolet Cobalt has been unfavorable. I have replaced the sunroof as the motor went out at 10,000 miles and I only used it about 12 times. The gear shift has been replaced 2 times (within 2 years). Park Chevrolet (Huntersville, NC) refused to replace it the 2nd time claiming I had spilled a drink on the shifter and that was why it was shifting badly (again). This was NOT true and was pointed out by another GM dealer and they DID replace it and lastly the wheel bearing went out. All this withing 20,000 miles on this vehicle. If there is such a thing as a "Lemon Law", I think this one fits my vehicle.

Thank you for your diagnosis, it was correct![/Quote:b8b68aa64f]

for a lemon law it has to be the same problem 4 times in for the same repair or they cant fix it ( same prob )

Truck? Cobalt is a car, if you are working on something other that is model CHEVROLET COBALT please start a new question.
