I bought this 2017 titan xd in Mar/20 and in the 2nd week of november 2021, it started to randomly vibrate. A constant,high frequency vibration that starts around 60km/h( 40mph-ish) . I've read a few different threads on a few different forums, and I've read everything from wheel bearings, tranny mounts, body mounts, bad driveline, bad tires. But I've only read a few that actually resolved the problem. I asked a diesel performance guy that seems knowledgeable with cummins motors says its probably the vibration damper on the crank. Is that a thing? Can anyone offer any insight?
