[Biturbos4] differential thump

[dap128]

There is a rubber/metal dampening mount on the front of the rear diff.  The 
rubber can tear and cause the diff to move more than normal, which in turn 
causes the driveshaft flange to hit the underbody.

The replacement mount can be had from online retailers for about $170.
