Drivetrain noise when coasting goes away under load. Noise doesn't change when loading (swerving) left or right. Drove it in circles both left and right in a parking lot and a tight circle produces an audible vibration.

Hi,

How would you best describe the noise? Is it loud enough to be recorded and uploaded for me to hear?

Also, have you checked for excessive play in the CV joints? They can cause vibration, noise, and so on as well. Take a look through this link and let me know if anything mirrors what you experienced:

Also, and this may sound crazy, but make sure the power steering fluid is clean and full. At low RPMs, it can cause noise and vibration under a load.

Let me know.
