3rd gen 6112 noise?

I've had 6112s on my 17 for about 30,000 miles now. They have been great everywhere. Just recently I started hearing a ting from the drivers front. It sounded like a brake pad catching on a rotor then falling while going slow.... and I had just gotten my front brakes done at the dealership. So I thought it was brakes. But looking and listening more closely, it happens on certain sized bumps while going slow, or when doing quick maneuvers fast. It's always the same light ting sound though, and almost sounds suspension related. Nothing feels loose and i can't replicate it by hand. Anyone have or heard of sounds like this with 6112s that have some miles on them?
