Its a very common thing on the F150 and most notice it at 50-60 mph. Do a quick google search and see how many you find. I just looked and theres a bunch

Hmm.... The vibration I get is most noticeable at 75+

75+ huh? I may have the same. Tires balanced, new suspension bushings, ball joints, alignment and at 75+ it shakes. I never do 75+ so really haven't looked into it

Yeah, it's there around 60, but it really gets noticeable the faster I go

Yeah, stock. I suppose if I went cheap they'd be that much. I've had my fill of cheap tires. I'm at Costco now getting them put in Michelin defenders. I dunno...maybe I am paying too much. Grand total was $920

$900 and change is the average around here. I'd say that price is fine
Tires for $4-500 aren’t going to be any good let alone vibration free. Should be $9-1,100 for anything decent.

I don't think balancing is your problem, but to play it safe does the a shop that did your balance have another shop to bring to, in case their machine is out of sync. Seen it happened to a friend here in Bay area. Can you borrow 2 wheels, actually 1, your spare, and another, put them both on front drive it. See what happens.
A drive shaft that's out of balance is like a bearing, it starts at around 40mph , just like a out of balance wheel, and gets worse as speed increases. Worn front end parts will usually not cause steering shake unless extremely worn. Tire tread/belt shift, or imbalance are first things to rule out. You mentioned the shop wanted to remove front drive shaft. Pull fuse #104 if 4 wheel drive is engaging, but that usually causes grinding not shaking. Were you four wheeling recently, that could have damaged front drive shaft?

Holy crap. Just got home after getting the new tires on. All problems solved and then some. Sooo much smoother and even quieter. I think the tires that were on it were a fleet tire and really stiff. I'm still really surprised that was the problem. You'd think a tire related problem would be there all the time and not intermittent like it was. My theory is that it was a cumulative affect. One or more tire would get things vibrating and and it would build and build until some sort of equilibrium was reached and it would smooth out. I suppose temps could have been a factor, too.... something would start to warp as they heated up or cooled down
Thanks for the ideas from everyone that chimed in
