I had a similar noise from the front end. Had the dealer check it out since it was already in to have the front wheel bearings replaced. They told me it was the sway bar links making the noise. You would never think that by looking at them. I'll try and change them myself since they wanted $150.00 to do it. Get them in parts store for $20.00 a piece. Also for anyone that thinks they might need wheel bearings try and get them replaced soon. Mine got so bad that they could not remove the old ones. I had to have the whole assembly replaced. Thankfully it was covered under the extended warranty. I also had them do the BG intake cleaning and power steering flush. I can't believe how much it helped. My steering use to feel a little sloppy. It is so tight now. Occasional low and rough idle is also now gone. That BG stuff really works.
