In my opinion, they are nothing more than a bandaid for what would seem to be a loss (or lack) of vacuum. If you want to simply lock the IWE's fully you can unplug the vacuum hose from the solenoid. This will leave the hubs engaged to the front diff and your 4WD control will still depend on your 4wd switch.
Personally, I'd just pull the electrical connector on the solenoid, IWEs will stay locked in. Does same as those other things, except it free.
Pulling the vac hose off will allow the engine to suck crap in thru the feed thru the solenoid, and also drop manifold vac.

OP, sounds like you may have blown out your checkvalve, you're putting more boost on it than I am with my EGO 3.5 tuned. You might try going to a tandem checkvalve arrangement like I have. Check out this photo.

yes, correct. I actually thought about this after i posted... If the line is pulled, it should be capped at the solenoid and plugged where it leads to the IWEs.

If you’re IWE’s are already trashed you may still get grinding so you might have to replace them anyways.

Yes, if they're trashed your gonna be in there anyway. You can pickup new OEM IWEs for about $36 a piece at Tasca though, less cost. And your truck would be factory like.
Please don't think I'm condemning what you plan, no way I'd do that, it's your truck and money YOU worked for it. No doubt there's a market out there, or they wouldn't be available, I'm just curious as to what advantage they are, opposed to just pulling the plug. If I'm not careful, I could learn something.
