Sounds like a bad axle u-joint. You can sometimes feel it in the steering wheel when making shape turns at low speeds.
When you inspect the front end, jack it up, turn the steering wheel to one side and then, one wheel at a time, rotate the wheel by hand, watching, listening and feeling for noise and looseness. Could also be a brake noise, which should be obvious when doing the above check.
