I have a 2006 Pontiac Torrent 2WD. As I accelerate I start to hear a loud humming coming from under the front of the car. It gets louder as speed increases. I have changed the transaxle fluid…no change. I know it’s not tire/road noise. It’s definitely mechanical. I can feel slight vibration in the peddles at 50 mph+ and when braking. Rotors machined and pads replaced recently and checked again by reputable brake shop. Possibly bearing/hub assembly? ---

could be, what about the cv joints? the wheel ballance? the alignment? ---

Ask the shop if they checked and repacked the wheel bearings when they did the rotors. ---

thanks for the response. balance and alignment are good and the noise doesn’t change when i turn corners so i had about ruled out cv joints (no clicking or grinding and such noise).
