^^^This. While not all cars have the issue, quite a few of us do (myself included). Ford has a TSB for it (what you are getting done), but very few have actually had the noise disappear for good afterwards.
While we shouldn't have to go to such extremes, the fixes outlined above have been what the really frustrated people have gotten to work. Check out the 2012 Titanium Front Strut Low Speed Noise (Clunk/Rattle) thread for more information...
