My front end has a "creak" / pop in the front when I cut it deep and the weight shifts just right... usually it involves an incline (such as turning into a driveway or turning as I cross a speed bump). Dealership refuses to touch it because they "can't reproduce", even though the techs have admitted hearing it while I'm driving it for them.
My Dad's a mechanic, so we jacked it up and wiggled around. I believe it's a buggered upper strut mount bearing. As the strut rotates, the bearing is binding and then popping free when there's horizontal stress. Just my total shot in the dark, but that's the area my noise is coming from. May not have anything to do with yours.
I don't think it's anything to be concerned about. Figured I'd just replace the whole works with an upgraded front suspension if it got too bad, and the heck with the dealership.
