clunking noise when I stop on 2003 Ford F-150

I am getting a clunking noise when I stop if the truck is not warmed up.
I have had the breaks and u joints checked but they can't find anything. Anything else I should be checking?

Does the noise happen when you slow down with out using the brakes?
check rear diff?
