There is no solenoid in the front diff pretty sure that's a soccer mom IFS Chevy thing... The factory hubs auto lock through a vacuum system. Seeing as you have warn hubs now that does not come into play anymore. (Good move by the way those auto lockers are POS) Now is the noise coming from your transfer case when you flip the switch or the axle itself? Turn the front drive shaft see if it is engaging properly. Also check your hub bearings if they are in super poor condition sometimes your auto lockers won't engage. I have seen it happen.
