Hi everyone,
I know this is an uncommon problem, but my OBXT was making some noise while driving. I am normally very good at troubleshooting issues, but I could not figure out what was creating this noise under acceleration.
I finally gave up and brought it into my local Subaru dealership so they can spend (1) hour to diagnose the issue. At the end of it, they took one of the rear differential drain plugs off to find a tooth broke off one of the gears and was stuck to the magnetic drain plug.
All that said, I will need to find a used replacement rear differential for my OBXT. I have done some searching, but have not found a concrete answer towards what other Subaru's have an interchangeable rear differential with mine.
Vehicle information:
Year: 2006
Model: Outback XT
Transmission: 5 Speed Manual
Final Drive Ratio: 4.44
Rear differential type: Viscous LSD (VLSD)
Can anyone give me a concrete answer on what other Subaru's have the differential I need? Obviously another MT OBXT would work, but they are pretty rare, hence why I am asking this question.
I believe some Foresters have the same F.D. ratio, but I do not think they are LSD?
Would a JDM WRX STI R160 4.44 LSD rear differential work? Similar to this:

Any concrete advice would be greatly appreciated! Sorry in advance as I feel like this question may have been asked before....
