2003 GS with automatic transmission and 102,000 miles makes a droning noise (about 1 Hz or 1 cycle/sec) from front end. Is noticeable from about 35 mph and faster. Seems like you can feel it through the body of the car. The frequency (1 Hz) really does not seem to change too much with speed, and will still occur even when coasting down hill in neutral or with power to the transmission. Any ideas what this could be?

It sounds much like a bad wheel bearing. Can you identify if it coming from the front or rear of the car or which side it is coming from? If it is the front does the noise change as you change the load from one side of the car to the other for example driving on a twisty mountain road taking a left turn vs a right long turn is the noise change?

Thank you for the reply.
Absoutely the front. Yes, noise changes . . . It is much more noticeable on a straight line, seems to get a little louder when making (at speed) sweeping left hand turns, not so noticeable when going to the right.
For what it's worth, I did jack the front of the car up and tried to "jiggle" the wheels. There did not seem to be any "play" whatsoever in the wheel assembly.
What's rough cost for replacement, and should I have both sides done at the same time?

Yup, it was the wheel bearing.
