Drive line vibration will be a much higher frequency buzzing-type vibration compared to a wheel's thump - thump vibration. The tires should be checked for a broken belt. Squirming in the outer tread is easy to spot but other things can show up that aren't so well-known. Anyone can spot a problem with a road force wheel balancer.

If you have cast wheels, Ford used to use a heavy locking lug nut on each one. Those needed a half ounce weight added to the wheel across from that nut to maintain wheel balance.
