Question about 2005 Ford F-150
IF this is a case that the IWEs will not disengage, it could be the IWE solenoid or the vacuum lines to the IWEs. Could also be a problem with the vent lines from the IWE ( the other vacuum line that runs up into the engine compartment, and just hangs there ).
This is the block diagram of the vacuum lines for the IWE ( not actual routing ). You can use a vacuum pump / gauge to see if the lines will hold vacuum. Don't be surprised if the vacuum lines test OK, there is a TSB on the IWE solenoid where it could ingest water, and allow water in the lines, which will not keep the IWE gears disengaged.

Ford does not have a vacume diagram for this system , the vacume has only two lines, one from the engine to the solenoid and one vacume harness that goes from the solenoid to both front wheel ends (hubs) Make note that vacume is supplied to the Intergrated wheel end(hubs) only when the truck is in 2wd and vacume is released in 4x4. So with out vacume supplied the wheel ends are engaged. Thankyou please rate this answer for me Have a good one RJ
