Need help identifying this noise (Videos Attached)

[MattL]

Hi all, I'm hoping someone can help me establish the cause of this noise. I've done some searching and from what I've read it could potentially be the IWE check valve or actuator spring washer kit as outlined in TSB 20-2016. However I wasn't able to find any videos to collaborate the noise.
The dealership had my truck last month for 2 weeks and since they couldn't replicate the noise they did nothing. I'm out of warranty at the end of the year so I'm dropping it off to them again Monday. I'm hoping I can point them in the right direction to get this resolved.
The noise is very inconsistent, I've not found any way to replicate it. As you'll see in the videos it occurs mostly at lower speeds and under acceleration but minimal load. Once the noise starts if I accelerate lightly the noise persists/increases and if I let off the gas it stops, If I accelerate quickly It'll increase for a couple of seconds until it makes a "clunk" type noise which sounds like something has locked into place at which point it goes away.
I appreciate the help, if you have any questions for me don't hesitate to ask.

You have to share them as Public for others to watch.
Unless you didn't publish them yet, either/or it's not working.

Hi guys, i'm dropping the truck off tomorrow. If anyone recognized this noise or can let me know if its not one of those issues it would be very helpful.

Can't make out any noise, sorry

Thanks for checking it out, its a bit tough to hear over the road noise but it helps to have the volume up. It resembles the noise made if you stick something into bicycle spokes.

I’m pretty sure I have the same problem. Twice now Ford says it’s normal. BS! Not normal at all. It’s more prevalent when it’s warm outside. And there is a shudder when that noise stops.

Here’s another video. Listen for the thud at the end. I notice it happens to me when I accelerate and the turbo is spooling up.

Yes that’s the noise I’m experiencing also. The thud when it stops is very noticeable. I read a post regarding the IWE check valve failing and the noise coming from the attempted shift from 2wd to 4wd. It recommended driving in 4 low which I’ve done for a week and haven’t experienced the noise since. My truck is at the dealer, I’ll keep you posted on the outcome

Thanks. I’ve taken to the dealership 2 times now and they say there’s nothing wrong and that sound is normal. Told them their crazy if they think that’s normal. After seeing your post, began reading more about the IWE and am now convinced that’s the problem. Sent dealer a message telling them that. Thanks for the response and let me know what they say.
