Cricket on the right rear quarter

Ok, so the '14 JSW has about 10K miles on it. When driving across a railroad track or on some of the rougher streets at low speeds, there is a chirp in the rear end, on the right side. Sounds like it's in time with the movement of the shocks. Any ideas?

All I can say is, noises are funny. I had a rattling sound that I swore up and down was coming from beneath my headliner.
The mechanic took a ride with me, it was rattling coins in the console.
Point being, just cause it *sounds* like it's coming from the right rear, doesn't mean it's coming from there...

I have a 2013 JSW with about 9200 miles on it. I am hearing a similar noise in that same area, under similar circumstances. My suspicion is that that it may have to do with the cargo cover, but I haven't had time to do any testing, such as driving around with the cargo cover closed or removed. I will try to do so and report back.
