Default Noise on decel

2012 fx4 with 5.0. Started to make a screeching whirling noise on decel at low speeds 1-3rd gear. Also noticed that front driveshaft cannot be turned by hand when in two wheel drive. Thanks for any help

Possible IWE.
jack up each front wheel and with engine running and in 2 wheel drive see if that axle turns when you spin the wheel by hand. If it does the IWE is toast. Could also be the tubes from the solenoid or solenoid itself

Are the hubs disengaged with--or without--vacuum? If the first, the front shaft wouldn't turn with the engine off (no vacuum).

In neutral with motor running it is free and don’t turn wheels.
