Didn't the blade diff bush's let go prematurely ? surely they did.
Looking at this from a bigger picture....

I could be wrong here, but it's possible it was seen as a cheaper solution to replace existing bushes that failed under warranty than the expense of a total new program to re engineer and evaluate a solution.

Once NVH becomes a consideration it limits the types of bush materials they could adopt for an easy fix.
