Well, the noise has gone away by itself, maybe due to the fact that the ambient temperature here in Kansas City is now well above freezing, as the wailing had occurred during the last several much cooler days. Or perhaps fluid that may have gotten onto the belt evaporated, or any air bubbles in the fluid may have dissipated due to driving after lowering the reservoir level.
Sorry I had initially forgotten to mention that the wailing seemed to be more related to acceleration rather than turning of the steering wheel, althouth it wailed simply idling. I’ll let you know if the wailing returns when colder temperatures return, supposedly this coming weekend.
At any rate thanks for all the great suggestions and assurances.
