Bought a 2002 Impreza Outback Sport 3 days ago with 170k miles and sadly there's already an issue on it. Found out yesterday that the front diff is going bad. It whines pretty obnoxiously from 30mph and on. Drained the fluid out yesterday and I saw a good amount of methal shaving on the magnetic plug.
Just in case it'll be too expensive to service the front diff, my other option is to source out another good working used transmission. So there in lies my question: Which other Subaru models share the same transmission and final drive ratios as my 2002 Impreza OBS? The transmission code is: TZ1A4ZCCCA.
Any input or advice are appreciated. Thanks in advance!
