But thanks for leading me down there, with the exception of my car being dead and the trip back it was a blast. 
The diff isn't soft. It's hard. It's brittle, meaning that it doesn't absorb shock loads very well. The diff is designed for high mileage, not high performance. Performance diff's don't last as long because they wear out faster being more ductile.
Hard = high wear characteristics, low strength
Soft = High strength, low wear characteristics.
Considering our tranny is for the Forcus/escort with a 4-banger I can see why the diff is too brittle for our engines.
Glad to see it was something cheap and inexpensive.
