I posted about this in a thread "Titled whirring sound on deceleration", but for convenience I'll post it here for you. Took the truck to my local dealer because I had a rattle that sounded like it was coming from under the truck in the back at about 900-1200 RPM. They said it sounded like it...

What is there to advise? It is a known issue that effects some, not all, and is fixable. If it happens, you can get it fixed, live with it or get rid of the truck. What are you afraid of exactly? You just have to decide your level of comfort. Ford says the cam phaser issue will not damage the...

I replaced my muffler with the Flowmaster FX, https://www.holley.com/products/exhaust/exhaust_systems/flowmaster/flowfx/parts/717776, and it solved the rattle as well. Thanks for the info.

Closing the loop on the thread. I ordered and installed myself the Flowmaster FlowFX muffler and the noise is indeed gone. Here's the one I ordered, https://www.holley.com/products/exhaust/exhaust_systems/flowmaster/flowfx/parts/717776. It has a bit throatier sound than stock but is not at all...

I hadn't seen this post before. Evidently this is a known issue. https://www.fordraptorforum.com/threads/exhaust-rattle-leads-to-replacing-a-turbo.57663/page-4

Same issue here, a metallic rattle coming from the passenger rear area at 900-1200 RPM once it has warmed up. My dealer told me it was something loose in the muffler, but not in warranty because I'm outside the bumper to bumper. Now I'm trying to decide which aftermarket exhaust to go with...

Same issue here. My dealer told me it was something loose in the muffler, but not in warranty because I'm outside the bumper to bumper. Now I'm trying to decide which aftermarket exhaust to go with. Here is my noise (phone just laying on the ground under the truck, not pointing toward the...

ok, well I dropped by the service department once the truck was warm and two techs came out to listen. They feel that it is something inside the muffler, such as a broken baffle or something. It is coming from under the truck and doesn't seem to be a lose clamp, shield etc. They have heard it...

I've read about the wastegate, not sure what I'd be looking for honestly. I took it in yesterday, played the video for them but then they couldn't get it to happen, although they admitted they didn't drive it very far so perhaps it wasn't warmed up enough. But they told me to drop by anytime it...

Ok so I am able to hear the noise when it is parked as well, as it turns out. It seems to be coming from underneath the truck and not in the engine bay. I don't feel anything loose, like an exhaust clamp, but can't be certain. The link is to a YouTube of the noise I made with my phone.

Ok, I posted my question right before I went off for a week of vacation so sorry it has taken me so long to get back. Putting it in 4A made no difference. It has definitely gotten louder, but doesn't record well due to cabin noises, etc., on my phone. I've decided to have it checked out at...

Not that I've noticed, but they are getting close to needing replacing. Next on my list. I'll give the 4a a try after work. If it is an IWE it goes away in 4wd, is that correct?

I was just going to add that I've only had it in 2wd and haven't experimented with the 4a.

Recently I've begun to hear a whirring sound when decelerating that seems to be coming from the passenger side on my '18 Screw. I think it is up front, but can't be certain. It is independent of braking, but always happens when slowing down, typically at lower speeds (<45mph perhaps). The best...
