Probably the IWE system, it's losing vacuum somewhere.

Does it sound like a rattling noise coming from one or both wheels? Like mentioned above, possibly 4wd hubs trying to engage. Get a vacuum tester, check the lines like the thread says. Or just get you a new check valve, $10, takes 30 seconds to swap out, and it's likely the fault, as they go bad and don't hold a vacuum well under load.

What troubleshooting steps led you to replacing the valve?

What valve did you replace that cost $88, Canadian or American? It's a cheap plastic check valve.

​​​​​​​ to properly diagnose read that thread and check the vacuum though.

That's why it was more, you replaced the entire switch. The cheap check valve is motorcraft part# YG429, for my 2010 anyway. It holds the vacuum and only allows air to flow one way.
