Both IWE actuators bad ???????
I've been having a slight vibration in my front end so on a whim I checked my 4x4 system the IWE actuator on both sides stay engaged when vacuum is taken away or applied.
Just so I'm clear after a lot of reading...This means they are bad,right?

how do you know theres vacuum at the IWE ? Vacuum applied to the IWE disengages the IWE.. you could have a leak in one of your lines that is preventing the IWE's for dis engaging .. perform a vacuum test using a vacuum pump before you start tossing parts at it.. there's also a couple check valves in the system after the IWE solenoid with also could be your culprit.

If I pull the lines off at the hub actuators when the truck is running there's plenty of vacuum in the lines...
I diagnosed it using this....
