I had a squeak around that area too. I found out that it was the body mount bolt that came a lil loose (after doing a body lift). It could be that. Maybe it could use a lil WD40 if its already tight

Another squeaky on mine is the bed(bent) rubbing on the cab. Plus a minor rattling/squeaky comes from the xcab window shaking. The lil gasket/putty wore off on the locking tab screws.
