Good stuff. I seem to have made all the same mistakes from the check valve and lines all the way down to the IWE 😂. I haven’t had to do the passenger side IWE yet - but everything down to it is brand new.

[@TrickShiftGarage]

That's good man. The more you replace, the better since these seem to fail very often.

[@causinghavoc1225]

Didn’t fix the problem for me but easy enough to replace

[@TrickShiftGarage]

Have you replaced the IWE's themselves? Those are notorious for failing.

[@causinghavoc1225]

@@TrickShiftGarage that’s what it’s looking like. I just tested the solenoid with a vacuum gauge and it seems fine. The noise completely stops when I go in 4WD.

[@TrickShiftGarage]

Yea that's how mine was. After replacing them, the noise was gone. Let me know how it goes bro!

[@Ellacost831]

So what was it doing when broken? Was it making noises in the wheels?

[@TrickShiftGarage]

There was intermittent grinding/scraping noises coming from the front end. It went away when I put the truck in 4WD, and since I had already replaced the IWE's, I knew it had to be the check valve or the solenoid.
