Steering hum,buzz on turns

I saw a thread, but can’t find it now. 2012. Just flushed the steering to eliminate howling noise. The pump is silent now lock to lock when parked, but there’s a buzz,hum while cornering in either direction while driving that seems to originate from the front generally. The noise disappears when the steering wheel is returned to center. Am I looking for a suspension problem, or a bearing?
