Hey kevo,

RobG is right on target, we have the option to install manual hubs on our trucks but I didn't want to spend the money right now. I did not make any changes to the xfer case at all, so when I push the 4WD button the front output shaft does engage. However, our SOTF mechanism is a vacuum opperated solenoid. All I did was to break the vacuum feed to this device. Now when 4WD is selected and the solenoid is energised it does not actually move because there is no vacuum present, therefore the front end does not engage.
