I got a couple pieces of 8 1/2 x 11 paper with mine with numbers all over them. Build sheets maybe? If so they are dated 3/17 so I assume that was the build date. I haven't detected any clunk yet but I still have less than 200 miles on it.
Your service department can look it up and tell you. Or if you want PM me your vin and I can look and see.
Mine is from 01/14/2011 and has the clunk. Wonder how i get this matter resolved since shipping my Raptor back to the US is not really an option.
That sucks. You could buy it and have it shipped over and installed if you really wanted. Or maybe Ford will send you one for free if you call them and tell them your situation.
