On Saturday my Forester developed a bad whine noise from the engine bay. Sounded almost like a supercharger or something.... I suspected the alternator at first, then quickly realized it was likely the AC idler pulley.

Sure enough after a quick listen with a stethoscope we determined my AC idler pulley was the culprit. Took about 5 minutes to replace. Pulley was $37.
