Periodic Noise

Wife’s car (1999 Subaru Legacy Outback with >140K miles) makes intermittent noise coming from the left front area. It seems to be a function related to a position / speed of the wheel. It makes a noise which varies from a rubbing low-frequency to a squeaking and high -pitch. We’ve brought it in to the dealer 3 times without resolution. When the car was in a noise mood, we brought it in to have the dealer tech listen to it and verify that we’re not crazy. I thought that it might be a stuck brake caliper, wheel bearing or speedometer cable. But nothing has been confirmed as yet. Besides turning up the radio to full volume - what do you recommend?

Eureka! - Problem has been diagnosed as front wheel bearing - very expensive…
