We have been hit with allot of these lately where there is a quite noticeable clicking noise only on turns. Some of these were even out of warranty already and figured there is likely many more of you out there dealing with this noise thinking you have a worn half shaft from a quick internet search. I am happy to say it is actually a much less involved fix and super cheap. In this video I go over what the noise sounds like and how to fix it up. This problem affects many Ford models from 2011-2013 but I have heard the same problem the other day on a 2014 I was driving. Hope this helps.
