Default Iwe solenoid humming/buzzing

Alright I have a 2011 ecoboost and after doing alot of reading I realized I had the rubbing/grinding sound of my iwe on the left front rim, I changed all my vacuum lines and it seems that, that sound is gone but when I'm idling I hear my solenoid have a loud humming/buzzing noise. If I shift into 4x4 the noise stops. Then I'll drive a little longer and when I stop I can hear it again. Then the same thing I put it int 4x4 and it stops. Anyone have any idea what I should do?

Possibly the solenoid is failed, check valve, or IWE itself.
