Both the hinges of the passenger windows of my 2002 Tundra Access Cab broke where they join the window. The piece that broke is plastic and attaches to a rod (the piece the gets pulled down by the cam action of the hinge) anchored to the window They both broke within the last 3 weeks (about 500 miles post warranty). Is this a common failure? Can I buy 1/2 a hinge? Thanks, Trevor
