Welcome to the Forum, read the stickys up top, there is a list of ratio's in the cars.

 

You may want to check out http://www.car-part.com get a junkyard unit.

Thanks for the reply! I checked out the stickys, and I'm having trouble finding the ratio for my exact model. A Subaru Legacy 2006 Limited 2.5 4AT. Any help would be greatly appreciated!

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!
