What year's the Ghia? I'm assuming that if they wanted to replace an axle we're talking about the late model with double-jointed (CV) axles. How are your tires and have you tried rotating them to see if the sound moves, too? An unbalanced wheel can eventually cause the tire to wear unevenly and make noise. Look for feathering on the tread blocks or any other signs of unusual wear. The sound in the front is screaming right-side wheel bearings, as that's where the load is in a left turn. Have you adjusted your rear brakes (and fronts, if they aren't discs-again, year-dependent)? The farther away they get from the drums, the more pedal travel. If you pump them quickly, they don't have time to retreat completely back, so you get a temporarily higher pedal.
