Significant Vibration from Rear at 60+ mph

My 2015 FiST vibrates significantly at 60+ mph. Before and after front tire replacement & alignment verification.

The vibration is not in the steering wheel; rather, coming up through the seats and I see the passenger seat shaking.

I went ahead and had both rear wheels balanced and the problem persists. Tires in great shape; no flat spots, no exposed or broken belts. Rims aren't out of shape / damaged.

Vibration at 60+ mph persists whether accelerating, braking, or coasting. Rear brakes are not stuck.

No noise to indicate bad wheel bearings. The chassis has 163k miles on it.

I welcome any input on possible issues.

Thank you!

Ever seen a car going down the highway and a rear tire is bouncing/shimmying as it goes down the road? That might be happening to you. Usually due to worn out shocks and possibly worn out bushings.
