3.6L Engine growling at 30+ MPH
All,
I am stumped. About 5 months ago, my CTS started having a whine like the belts were being dragged. I had recently replaced the Alternator, so I had replaced the belts within the last 10 months. I've only owned the car a little over a year. With that said, I went ahead and replaced the Tensioner Pulleys and the idler pulley. About 2 weeks ago, the whine came back, not as loud but very similar, when I made long left turns, the sound would go away; so I replaced the Power Steering Pump. Now the Whine is gone, but I have a growl that kicks in above 30+ MPH. This growl could have been masked by the whine, I am not sure. All I know is the Growl gets louder the faster I go. At 65+ MPH the steering wheel starts to oscillate.
Any help is greatly appreciated as I am totally stumped.
Thank you,
