2013 BMW 535 - Hum



I have a drive train vibration issue that I understand has been an issue with my make/model. Specifically, I feel a pronounced vibration with an associated hum starting around 50 mph. Has anyone experienced this issue? If so, what’s the fix?


awd? 2 piece rear driveshaft? inspect the support bearing if it has one. since most awd vehicles have one i would start with the driveline
