Hi all, my 2006 Subaru Legacy Limited w/Automatic Transmission has been leaking rear diff fluid and has a whining noise while coasting, and a grinding noise while going highway speeds. Now I'm getting some vibration and shudders in stop and go traffic...
I'm worried that I might have to replace my rear diff at some point, but I'm having trouble determining exactly what ratio will fit my Legacy Limited. I found this part number (38312AA022) on the Subaru parts website and it's been discontinued, but I couldn't figure out the size or ratio, or if other rear diffs would fit my car. Any help on this subject would be very much appreciated. Thanks!
