I'd be curious to see what happens if you swap the front and rear wheels.

If I may add my 2 cents, Joe. I honestly don't have an answer to help you solve your concern, However, I can only point out that I've done a lot of reading on the subject of road vibration much of which has been documented on other forums such as the Ford Fusion Forum and others, and while those particular incidents may not be exactly what you are now experiencing, the issue obviously presents itself from time to time.
In my case I had experienced what may be referred to as a quiver like sensation in the ride on my 2017 MKZ Hybrid, this since purchasing it in late June of 2017. While I've felt that much of what can be done has already been done to correct this issue, and the ride improved,
I honestly can't say it has gone completely away. To be frank, it's noticeable to both my wife and I at low speed, as well as highway speeds. It may very well be inherent in this particular automobile, not sure.

To answer your initial question about the outcome of my situation, Joe, I ended up replacing all of the tires. (Previously, I'd replaced one, then two...finally replaced the last two.) That was the suggestion of someone here since my car is AWD. That did improve the situation. But honestly, it never went away. Was still feeling some vibration, mostly in the seat, at speeds below 50.
I took it to the tire store recently to have them check balance and alignment and they discovered again said one wheel was bent; they'd said that during the previous incident, but Lincoln checked and said it wasn't. So paid to have it fixed. That seemed to have a pretty noticeable impact. It still has just a slight vibration, at the lower speeds, more pronounced when I first start driving and lessening the longer I drive.
I also wanted them to balance and rotate before putting returning the car to me. But because a week passed (between taking the wheel off and replacing it--I travel most weeks and had to come back), and with some confusion at the tire store (including a power outage), I'm not 100% convinced they did. So I'm going to take it back and have them do it again in case that solves the problem for good.
Based on this whole ordeal, I've lost faith in the dealer's service department. I hope it's just this dealer and not indicative of Lincoln, but they are pretty apathetic and clueless and have done some questionable things, as pointed out earlier. Unfortunately, the next closest dealer is about 40 miles away so I don't have a lot of choices. But will impact my likelihood to stick with Lincoln when I replace this car.
Good luck on figuring out your problem!

I dropped off my car at the dealer this morning, 10-10-17.
They took seriously my complaint of "vibration, shimmy at 45 MPH". They gave me a loaner which is a 2016 MKX. They anticipate that it may take more than one day to correct.
If I were a SUV person I would probably have a MKX. It is nicely appointed and rides very nice.

I will keep adding information as it occurs.
Got a call from the dealer today (10-11-17). He wanted me to come in and go on a road test with the mechanic.
The mechanic told me that he had replaced a bearing (can't remember where) and wanted to determine if the problem still exists, before he returned it to me. I drove and we got on Interstate 87. Right on Que at 45 MPH the problem became evident. He could feel if just like I could. He also had me accelerate to see at what speed it stopped. He said now he has a good idea of what to correct. He told me it may take another couple of days. Since I have a loaner and this is being done under the warranty I told him that's just fine.

I received a call from the Service Writer today (10-16-2017). He advised that the technician was still working on my car. He expects it to take a few more days for completion.
The reason I'm posting these "progress reports" is to demonstrate that there are good dealers out there who do the right thing. This should embolden you to demand good treatment from your dealership.
My dealer sells and services Lincoln, Ford, Mazda and Subaru. It is a large dealership, but still takes the time to provide "personal" one-on-one service.

I received a call from the Service Writer today (10-17-2017). He advised that my car was ready for pickup. Picked up the car and checked it out on the way home. The problem is no more.
The write up on the repair order was "Customer states check for vibration felt in driver seat when driving at 45 MPH without brakes applied. Customer indicated front wheel balance is OK. If necessary balance wheels."
They replaced the R/F wheel hub bearing - Part # DG9Z*1104*E - Hub Asy Wheel x 2
Replaced the Power Takeoff Unit - Part # DT4Z*7251*G - Power Take Off Asy
Parts cost $941.09. My cost along with the use of a 2016 MKX loaner and car wash was $0.00.
Just for your information my car is a 2014 MKz AWD with the 3.7L 300HP engine. Elapsed time for repair 5 working days.

This is the final update. I was mistaken above in that the problem had not been resolved. I took it back to the dealer.
This time they replaced the drive shaft. Part # DP5Z-4R602-A, Shaft Asy - Drive, It shows the cost as $404.46.
This time the problem was really corrected.
Again, all of this was covered under my warranty at no cost to me. I was also provided with a 2017 Lincoln MKX loaner. It only had 134 miles on it.

The two parts that they first replaced were found to be damaged and needed replacement. They had the potential to be causing the problem. They had probably been damaged with the pot hole situation. With those eliminated they focused on the driveshaft.

Thanks for the update, Joe. I'm surprised that they warranteed all those parts it they were damaged by a pothole, but who's to argue?
While I admire the dealer's persistence in solving the problem, I am not impressed that they continued to throw parts at it which it likely didn't need. Not sure why they couldn't have diagnosed the driveshaft issue to begin with.
Happens all the time. I complained about a brief vibration at 40mph/1500rpm in my 2010 MKZ AWD. At the behest of Ford Engineering, they replaced the torque converter, rear differential and TCM and then finally decided that it was an inherent condition with this driveline configuration. It was caused by the rear diff disengaging and the TC locking up at the same time. They said they would work on a recalibration but it would have to be approved by the EPA. I'm still waiting, 7 years and 4 cars later. Turns out, they all do it to some degree. My 2012 and 2014 did it and even this 2017 occasionally does it. There's a thread on it on the Ford Fusion Forum. It's gotten less noticeable with each successive model, so I guess they have tried to mitigate it.

Artie when I had the pot hole encounter I went to the dealer, driving on the temporary spare. So, they saw how the tire had been destroyed.
I told them to check everything to determine if there was any other damage. They did and said that everything looked good.
Later on when I developed the problem with the shimmy and vibration these issues were not connected to the pot hole.
