Can't believe we've reached this milestone....
Tomorrow the car will have spent 15 days total in the shop and it will be getting its third repair. The parts didn't arrive today at the service dealer, but should arrive tomorrow. As the shop is open later until 7pm, the car should have the intermediate bearings installed and ready to go before they close.
For now, I'm preparing a vehicle defect notification form and will be sending that in on Wednesday should the vibration not be gone after this fix. According to Florida's Lemon Law, this notification form must be sent to Ford once the car has had 3 repairs for one issue or when the car has spent 15 days out of service. Lucky me, my car meets two of those criteria *facepalm*
