The first mechanic said a propeller shaft bearing and he used the "ears". I have no fricken idea what that is, I told him I did not have an airplane and he laughed at me. When I took it to Subaru I told them after finding out this Propeller shaft bearing is actually a TSB, that this was suspected as the sound, and they seemed to ignore me. I will call and set up ANOTHER appoinment.
