I've been hearing a loud snapping sound recently. It sounds like it's either coming from the door (mainly on the driver's side, but sometimes I'll hear it a bit on the other side of the car) or somewhere around the b-pillar. It happens during turning and going over bumps. For example, when I make a turn off a main road onto a side street I'll hear it. Or, when go over the skirt at the bottom of my driveway when I pull in I hear it as well.

I searched the boards but didn't see anything posted yet that relates to this. Anyone else getting this noise? This is just adding to the the list of odd noises my car has been making since around 3k miles.
