Hi guys.. I recently noticed a annoying noise while driving my wrx wagon (2002) (no major mods on my wrx) only TT, BC and a BOV.. This whining sounds appear while I'm driving btwn 20mph -- 50mph once reach higher speeds it seems to disappear. I've checked all around .. nothing scrapping the floor or the tires... I could hear it real clear inside the car.. but once I open the window.. I dont hear much. I got a feeling its the alternator..or some pully.. Did any of you have this problem??
