I have heard this since I bought the truck two years ago and I am at the point where I am about to go drop it on Ford's doorstep and tell them to figure it out...but maybe someone else knows what this is. So basically when on a small incline or turn into a bump and my truck flexes...or when my passenger rear tire goes in the fender well it makes this loud "hit" sound....sounds like my leaf springs just cracked in half or something just nailed the inner fender well...I don't know what the hell this is....I just replaced shocks too and it still does this mess.
