2017 G31 in for a strange noise on deceleration
This G31 came in with a strange vibration and grinding noise, particularly noticeable whenever there was no load on the drivetrain.
After a quick test drive, it was clear we had an issue within the driveline. We got the car up in the air and quickly found the culprit , a completely perished flex disc (donut) at the rear differential.
A new replacement was fitted straight off the shelf, followed by a thorough road test to make sure everything was running as it should.
✅ Fault diagnosed
