Integrated front wheel hub 4wd grinding $20 upgrade. “Save your front wheel hubs easily”

So I took my car to the dealer and asked him if this can be changed in my 22 timberline.
Unfortunately they say the vacuum is controlled through the TCM and no such valve exists in this model.
Wonder if that is any true.
If so how can the problem be fixed because I still get the noise occasionally.

In mid 21 they did change to an electrically operated IWE and no more vacuum. Bet you just had a bad IWE.

I believe so.
the sound still coming out occasionally and now in 4A or 4H the is a hauling sound which wasn’t there. I winder if it is connected to IWE.

Thanks for the post. I don’t see this type of hose setup in my 2023 XLT. I hope the new design is as good as the one with the blue vacuum hose
