I would be betting pints that it is one of the propshaft joints. It's unlikely to be a rear CV joint as there's little to no power going to them at 50 mph.
If the front or rear prop joint has play in it, the whole propshaft can resonate and create a whiny droning noise. This gets substantially worse at around 55 mph when the torque converter locks as more of the engine vibration is transmitted through the drivetrain.
