Weird clicking sound as I accelerate out of corners.

Experiencing an odd effect here. My car is running fine, but when I accelerate out of corners, there's a metallic clicking noise that is very loud. It only clicks while I have my foot on the gas; when I let off it goes away and doesn't come back. It sounds like something may be making contact with the driveshaft or wheels, but I'm not seeing any clearance issues at all under here. Driving down the road it's nonexistent.

As o said, it sounds metallic, like contact, though sometimes I swear it sounds like something is sparking. That said, it doesn't dim the lights or cause any charging issues at all.

Any ideas where to look? I'm stumped.
only on corners? could be the rear diff
