IWE issues
I started a different thread about how much trouble I’ve had with my IWE. My IWE grinds usually when I leave the drive way and does it for a little bit. It has done it at interstate speeds but mostly just at take off. Now I have a question. A poster in the thread mentioned that his friends wheel feel off, so this got me thinking. What is this damaging when it’s grinding? What kind of repairs can I expect in the future? Thank you all.

His wheel fell off because of a grinding IWE? Makes sense it was a "friends", and not his. What thread was this in?Anyway, you can expect to replace the IWE since it's been grinding for what seems like a while. What I'd do, is find out why it's grinding, fix that, and then replace the IWE. The first thing I'd do is replace the checkvalve, buy a cheap little vacuum pump from Harbor Freight, and make sure you don't have any vacuum leaks in the hoses or IWE seals.
Then get back on here and let us know what you find.
I mention the checkvalve because it's the easiest and cheapest part to replace, and fixed more than one guys problem, myself included.

This guy has a couple videos you might want to watch regarding the IWE system.

Since you're taking it in, hopefully it's a dealer that is aware of a TSB regarding this system. Is it on an '05, or a later model truck?
If it's a later model, '15+, I'll see if I still have a copy of that TSB.

If it's a later model, if you pull the connector on the solenoid, the IWE's would stay locked in. Won't hurt anything as long as you don't shift into 4X4 on high traction surface. If you have 4A, just throw it in. What happens in either case, vacuum is vented off, and the IWE's close in, preventing anymore grinding and damage.

Sure, here's a photo. See that hose crossing over the brake reservoir? Follow it down, and it connects right there at the solenoid. Just disconnect the electrical connector right there.
No, you won't hurt a thing as long as you don't put it in 4X4 on high traction surfaces. Just drive as you usually do.
