Have them X the wheels/tires and see if the shake changes.
They won't get the driveshaft back until later this week, at which point we will see if it still shakes. If it does I suspect not a soul at that dealer will like me by the time I leave.
Balise Ford called right as I was getting out of work, their driveline shop says that I have a bad slip joint. $525 to fix including dealer labor. I suspect this will fix the loud humming noise I'm hearing at highway speeds, but the vibration feels like tires to me.
We'll see.
For me humming noise at highway speed started at 60mph and progressed to a roar as time went on and was accompanied by vibration - ended up being a bent yoke on the front of my rear drive shaft AND my rear wheel bearings. Fixed yoke first and the vibration went away, but sound remained, did the bearings and it was quiet as a mouse. So anyway my point if if your yoke is 'in fact" bad I have been there done that and it caused hwy speed vibrations exactly like you describe in your OP.

That might not fix the problem, BUT the $12 U-joint they replace at the same time might.
Hope they got you fixed up Crazy. If you still have problems, see if the dealership can try swapping some wheels/tires of something on the lot and see how it does.
$560 later I have a shiny black driveshaft. The ride feels smoother on the highway, but it still seems to shake some. I'll need to drive it some more before coming to any conclusions...
