Car is a 2010 Falcon FG (XT). Two weeks back had the rear diff bushes replaced as they were worn. Fast forward this weekend, heard a weird sound when driving but didn't notice anything obvious. Luckily was only a few hundred metres away. Parked overnight and by next morning the car had leaked a ton of diff oil in the garage. Car has been towed to the mechanic. Waiting for his diagnosis.
From a layman point of view, it seems like something went wrong with the recent diff service. Is there something about a diff service that could've caused such a failure? I just want to be armed with info before I go to the mechanic.
