Driveline vibration...solved!

Thanks for the post. I have a vibration issue and yoke has some play in the transmission tailshaft. Think it is a driveline issue based on behavior and when it happens. Good to know the yoke/bushing can be the cause.
Did you explore if the wear was the result of something else being off or possibly just from normal use over time?
I am wondering if in my case it could be a symptom of something else going out or worn (inside transmission or drive shaft alignment/angle etc.)
