I got the same thing. My armrest clicks when I hit bumps or rough roads. I think it is a little loose from me leaning on it when I enter the car. If I ride with my right elbow pushed over to the center or passenger side of the armrest the click does not occur. My Camry is presently at the service center for another noise fix and I am going to have them address the loose armrest issue. I will let you know what happens.
