While searching for the solution to my F150 slip-bump and take off shudder I've determined I need to learn more about my transfer case. Its a 2011 F150 which I believe sports the Borg-Warner 4419 transfer case. This is an ESOF (electronic shift on the fly) unit. Specifically, I am trying to determine whether the output shaft is isolated from the fluid and how the splines and output shaft bushing are lubricated.
