Would the hub itself affect the vacuum? Or would it just affect the actuator’s ability to mesh when released?

What, you say ford designed it so the hubs stay engaged? Not sure I buy this one
The Hubs holding vacuum disengages the shaft ends when you loose vacuum it will engage the ends. Make sure your testing the correct position on the IWE and when applying vacuum see if it stays steady and also on jack stands spin the wheel while it’s holding Vacuum see if it changes.
The strategy he posted is correct; the hubs remain engaged on startup to allow vacuum to build and to warm up the differential fluid.

So the truck opens a solenoid valve after a certain distance. Well how do you test it? Your in a shop, going nowhere and could not disengage or spin the wheel.
If you’re in a shop I hope the temperature is above 32F.

You still have a half mile to travel at above 32F according to the strategy
Drive it around the block before pulling it into the shop?

You just don’t get it. You shut the truck off and doing anything, then you need another half mile. Know wonder all/most techs are air heads, they leave the truck running after driving it around the block. Ford is gassing our tech’s
