Q: Helicopter noise / vibration when driving.

asked by on

I've replaced most of the front end: CV axles, bearings, etc. Have run the car on a jack stand a narrowed noise to driver's side. Have run it without the wheel or rotor to eliminate a tight caliper and warped rotor. Changed front left bearing twice, just to be sure. Out of ideas.

My car has 146000 miles.
My car has an automatic transmission.

Hi there. The noise is coming from the transmission. The noise could be a gear set inside the transmission with a broken tooth causing the vehicle to shake and sound like a helicopter. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your transmission.
