I have a 01 dodge 5. 9 4x4 one ton that is broken and waiting on the vaccum switch that enages the front cad axle, does anybody know it the 07 truck switch is the same as the older models switches?? Its a small switch with a dentent ball that sends vaccum to the cad that sits on the top of the front axle. Dodge is backorded and i can not find one anywhere for sale??
