vacuum line for automatic hubs
I have a 99 Ford F-350 and am having problems with the automatic hubs. I have gone thru the hubs and they are fine. Checked the vacuum line and there is no vacuum to them. I need some assistance on finding the valve in the engine compartment.
any help will be greatly appreciated

Welcome to the site!
If I remember correctly, the hubs are engaged and dis-engaged with vacuum 'pulses'. A constat vacuum is not placed on the hub during operation.
Regardless, the control unit is on the passenger side of the engine compartment. Follow the lines on that side of the truck.
Finally, have you checked the switch on the dash? It's not unheard-of for them to fail.
