Vibration at speed is not a motor mount.

You've got something up with and out of balance wheel, misalignment, or as you said, a wheel bearing. A bad engine mount would give you lots of vibration at idle when the engine is not revving quickly. At 65-80 mph the engine is revving around 2500rpm. If you rev the engine in park you'll notice it smooths out a lot once you get past, oh, 1000rpm and stays pretty smooth.
