Hi All...
I own a 2003 CTS with 42,000 miles.
I know that a lot of people post about the whining noise that comes from the rear of the car. Most people say it's the rear dif. So, I don't want to double post, but I don't think that it is the dif...it seems like mine doesn't fit all the symptoms of the bad rear dif problem.
First off, it sounds like it's coming from the front. Specifically the front right. I know sounds can be deceiving, but it does sound like its from the front right and not the rear.
Is definitely a very pronounced whining noise. No Grinding or rumbling.
Heard almost exclusively while coasting. (so far)
Between 25-55 mph. And goes away when out of that range.
Starts whining about 5 minutes into my drive, and then continues maybe the next 10 - 15 minutes while in that speed range. And then it kind of goes away....
Gas Mileage is normal.
Acceleration and deceleration feel normal. No Shaking or grinding or loss of power.
Still need to experiment more with turning while the whining is sounding. I know if the tone changes while turning it could be a wheel bearing or power steering. But so far, it seems to stay constant while turning or going straight.
I have taken off the Traction Control. It still happens with it off.
Also, I have put it into neutral while the noise is present. It seems to have no effect on the noise.
Recent work to the car:
I just put on new tires. Not cheap ones... So I doubt it's tire noise.
Just replaced the sway bar links/bushings.
The dealer put on New BrakePads and rotors when I bought the car about 500 miles ago.
Anybody with more knowledge and experience than me have any input????
Thanks for your time and help.
