The dealer won't that at a high enough speed, they did it at my 55mph or so and didn't hear anything.

To be clear though, I am pretty sure I know what the issue is, since the symptoms are EXACTLY the same as the numerous owners in the threads I noted above, all of which turned out to be a known flaw with the differential. So as much as I appreaciate the input; I am looking for advice to remedy the issue with the differential, not diagnostics.

Thnx
