At approximately 10mph, over small, sharp irregularities, such as rough asphalt, or concrete slab gaps there's a noise like a Frisbee being knuckle rapped. Seems to happen after car is warmed up. Have already tapped/damped various plastic underbody panels, trunk lid, trunk panels and a cover panel under the passenger side dash to no avail.

Had a very similar noise from the rear years ago. A dealer changed many suspension components (under warranty), which fixed the problem, but couldn't say what the actual cause was. I'm hoping it had to do more with tightening something, even some panel, especially now being out of warranty.

One suggestion over at PPBB is to check the sway bar bolt torques. Haven't gotten to that yet, but if anybody has a definitive answer, let me know.

Thanks
