I've had axle joints go bad silently, mostly you feel them when parking. Turn into a space, you feel a gentle tugging side to side. It sounds to me you're hearing a wheel bearing failing. Turning a corner shifts the vehicle's weight, alternately loading and unloading weight on the bearings. How old? How many miles? You're probably due. And, while they're out, do the u-joints while your hands are dirty. There are a few good threads about doing both jobs.Good luck.
