I'm betting your diff is fine. Make sure they check the axles too - as they're commonly a casualty after the diff mount failure.

Excellent post for those who are making power and still running the stock diff mount. If and when it fails, it takes the driveline and axles with it. While not low cost, a billet unit pays for itself.

Thanks for the good suggestions Doctor_X. I will check into the axles and upgraded diff mount.
