Just back from a 5000 mile run around Europe in the Escort. On the last couple of days I started to hear a continuous whine/hum when rolling. When the steering turns to the right the hum disappears then comes back on normal running or left turning. I suspected the wheel bearings but I jacked it up and both (front) wheels rotate smoothly and no play. The driveshaft gaiters do not seem to be leaking.
