So i have noticed this whining sound..It kind a follows the speed of the car but only comes alive when I touch the throttle. It dissapears when i put the shifter i N. No sound when just rolling. But very destinct sound as soon as i touch the throttle. Scraping at low speeds, as a bad ball bearing, high pitch sound when going at 60. If I speed up, higher pitch. So what the f@ck is going on...pardon my french here

Torque converter bolt has come loose. Time for a better look/listen.

Also check your U-Joints. Gotta be one of the above in the driveline. Let us know what you find.

I'm going with the rear end. Specifically, the pinion bearings.
