04-08 is mounted on the firewall behind the battery passenger side..

Appreciate the write up, John.

Quick question: how did you implement the second check valve? Was any cutting required? Any other materials needed?

Thank you. I just took a pair of diagonal cutters to the hose where I wanted to put the second checkvalve and cut it. It was probably down around 0F when I did it, so the hose was pretty stiff. I took a 500 watt halogen work light, and let it sit close to the hose for 15-20 minutes, and it warmed the hose enough to be pliable. Only part needed was the checkvalve.

Excellent - thanks! My next question: we're replacing the stock part with the same exact part from the same manufacturer. I'm assuming this is because the part can only endure so much use before failing? If so, should we be chalking this part up as a regular maintenance item to replace, or is there perhaps some reason we can expect the replacement to last longer than the stock unit?

No guarantees. Just like there are probably lots of 150 owners that have never had any issues. Luck of the draw. My truck is a 2010 and it had the issue shortly after I bought it used mid last year. Less than 55,000 miles on it but, it was 7 years old.

So, it probably would pay to have one in the glove box just in case. However, I have yet to read where someone had one fail completely. Always intermittently.

Yep, there's no rhyme or reason when the valve can go bad, and being intermittent, it's hard to find by a dealer, I'm being nice here. But at the same time, it wouldn't surprise me to find that some dealers have maybe a less than stellar tech working on it, it's been known to happen. Maybe with more experience, a tech might know just how this system works. It's a pretty simple system, no invisible magic like electronics,maybe that's the problem?
Mine failed on my '17 with only around 500 miles on it. The one in my '12 was never a problem with 58K on it when I sold it, I was the only owner until then.
So, I guess to be on the safe side, buy yourself one for a spare, and/or install a second one like myself and a couple others.

My 14 failed in June 2017 and the dealer replaced both IEW's and the hose assembly under warranty. Then if failed again Dec 2017 but out of warranty for the 3/36 bumper to bumper. But they took care of it because of the Ford 12 month 12k mile warranty on the parts. Both IEW's were replaced this time. The strange thing is I thought it was just the drivers side since that's where I felt it, floorboard area and slightly through the steering wheel. Yet they said the passengers side was faulty as well.
Good news is it now shifts in and out of 4wd like it did when it was new. There was something about that June 2017 installation that didn't feel right in regards to how smoothly it engaged and disengaged. It did allow it to go into and out of 4wd but had delays and at times a grinding, like one or both IWE's were "thinking" about it.

Did they replace the checkvalve or the solenoid too?

Thanks, I actually dropped my truck of at the dealer this morning because the drivers side has intermittent issues with the IWE. If they don't fix it ill buy and install one of these.
