I must confess that to date I have underused the features of my Rubicon. Now that I am officialy retired, I hope to correct this. This weekend, I drove through a Miss. River wildlife refuge in low range with both axles locked on the dirt and gravel roads. First time I've had them locked since big snow last winter. How often do you need to use the features to keep them lubricated. Wisconsin is pretty flat really and haven't seen the need to use the sway bar disconnect much at all. What kind of terrain warrents it use and is there a lubrication issue with that. I haven't used that since I picked up the Jeep from the dealership.
