Sorry for the delayed response to your test of "gunning it" while turning. It sounds like your "test" I was describing was successful and you didn't hear or feel anything out of the ordinary.

The sound (and vibration) that you could've heard would have originated from the center of the car toward the rear of the center console. This car has a two-piece driveshaft with a U-joint in the middle. On the driveshaft in front of the U-joint is the center support bearing. This bearing helps keep the driveshaft in place. When the rubber bushing for that bearing wears out the driveshaft will "flop around". One of the symptoms is when you are making a hard turn and giving some extra love on the gas, the g-force that pushes you to one side of the car will be doing the same thing to the driveshaft if the bushing is bad. This makes the shaft go all crazy and thump around like an unbalanced spinning top.

As several helpful members have pointed out make sure you complete the checklist of top items for this car. I myself just purchased a 05 and am waiting for the weather to be a bit more stable. I have a list of items on the driver side that I need to take care of like: Sticky Key solution, Power seat relay replacement, and seat heater repair just to name a few.

Good luck and welcome to the group.
