Thank you for posting this information. I agree that there are a lot of issues with these trucks.

Very helpful. Same issues on a 2014 F150 in Canada, worse in cold weather.

So, my journey:

Excellent video sir, thank you.

I changed the check valve and tube assembly after watching this video yesterday and sure enough it fixed the rubbing noise while in 2wd. 2019 f-150 2.7ecoboost

Thanks. I learned something here.

Mines doing the same thing. Only like once a month tho. I thought I was dragging something!!! Lol. Ordered the part thabks for the vid

Great video, thanks for the explanation.

Ford sent a Technical Service Bulletin #22-2219. Mine was the drivers side IWE

Was the sound like a clicking kinda like a card in a bike wheel

Good explanation. After I changed the check valve assembly more new problems came up. ABS light and Service Advancetrac warning lights came up. I am so discouraged and not sure what to do next. Anyone got same problem before? Solenoid is brand new as well.

Is it possible only to hear the noise when the truck is accelerating?

Thx!

Sorry but looks like you have it plug in the wrong position of the vacuum isn’t the one on top that goes to the bottom ?? In my truck was different , any results after driving like that in you experience?😊

Im still getting the rubbing tire noise even after i replaced the IWE and solenood

Good video. How many miles on your truck when you did the headers?

This being a year old video. Can I still drive the truck?

Hey so when you said if you put it into 4wd and the noise stops that's another way to tell that you have a bad valve check. What if the noise doesn't stop? I can't figure out mine. 2013 f150. Got new rims and tires and now bad scraping noise on front driver side.

Can u switch it to 4wd while moving? Isn't that bad? I thought u had to come to a complete stop

i live in NYC and ive been to like 10 mechanics and NOBODY knows how to change Hub actuator, and ford is trying to charge me almost $700
