2005 Chevy Equinox Diagnosing this Problem

Hi,

The vehicle makes a low "grumbling" when first starting to move, "grumbling" diminishes when speeding up turning into more of a "whirring/whining" sound that increases with vehicle speed.

Transmission shifts do not change the sound.

As speed increases/decreases, the sound increases/decreases it's pitch accordingly.

An associated vibration goes along with this nose, and it "feels" like it's coming from the front left wheel, even though the vehicle has new front rotors/pads and a new front left hub assembly.

At higher speeds (50+) the sound gets higher, and the radio is needed if you wish to drown the sound out.

I read about a driveshaft "hanger?" Bearing but I'm not familiar enough with it to know what/where.

PLUS: It's 9 degrees here in NH right now so I'm not exactly crawling around under it looking for the problem.

Anyone have any educated guesses?

Thanks folks!

Happy New Year!
