Need help identifying this sound
The sound is a rhythmic series of clicks in sync with wheel speed seeming to come from the passenger rear wheel. It resembles the sound of playing cards in bicycle spokes, if you were to use sheet metal instead of cards
The sound started after transporting the car on a trailer. Before this, there was no sound at all.
So far I have inspected the area, removed the wheel verified there was no debris. I thought the sound might be the brake pad warning on my D/S rotors, but there is plenty of meat on the pads and the rotors look normal.
The sound does NOT happen when the car is lifted off it's wheels....making it nearly impossible to identify it's location.
Any ideas?

Bearing? Either wheel or diff axle bearing. Usually they are more like a rumble.
CV joint?.....no really like that either.
A wheel bearing might allow the rotor to hit the caliper when there is weight on the car.
That's a tough one.

Doesn't really sound like a wheel bearing to me. It almost sounds like maybe your e-brake cable or something like that is rubbing someplace. If you have access to a lift that the suspention will be like on the ground I would check to see what the clearances are on everything that's routed around the rearend and shafts. Good luck with it.

Good news! As I was typing, I realized i had ramps in the garage. I pulled it up on the ramps and found the brake line was unusually close to both the passenger output shaft boot and frame rail. It must have moved while the car was being transported. The suspension undoubtedly saw more action on the trailer than it EVER would on the road. I moved the lines, drove it and no more noise.
Free/instant fix. Can't be happier.
Something to note if you ever trailer your car....especially through construction zones in Indiana.
