Rear Knock Developed @ 7,000mi

I've been hearing a pretty noticeable knock/pop/crack sound from my passenger-side rear corner for a month or so now.

It started around 7,000mi, so I brought the car in to Capitol Subaru service, they did a quick inspection and test drive, and found nothing. (I got back in the car and the radio was on, were they listening for the noise or just cruising in my car?)

A few weeks later, I brought the car to Stevens Creek service (wayyy better service here, as I'll soon discover) for my 7,500mi appointment. I had them do another check and they discovered the sway bar link nut was loose by about 3 full turns.

Well... turns out that wasn't the problem. I let two weeks go by, and now the knock happens over any uneven road surface at any speed. (video link below) I brought the car back to Stevens Creek this morning and the service manager took the car for a spin, he heard it immediately. They said the car isn't safe to drive and gave me a 2015 Forester loaner. I'll keep you all updated!
