'97 Explorer AWD, 5.0, recent hum from front axle. When lifted, axle is engaged and hot after only 4 or 5 miles. Chilton book says there is a vacuum disconnect axle lock instead of auto hubs. Cannot find this is on the axle. The diagram is an exploded view but not how it is connected to the axle.
Any thoughts of how this could be engaged? Vacuum lock or computer?
Thanks
