Hey guys i have a 2014 EB with 13k miles and recently noticed a rattling noise coming from the drivers side when I accelerate slowly from a stop right around 1000 RPM. I can replicate the sound fairly easily in first and reverse. Brought it to ford and they said they couldn't hear anything. Of Course. Wanted to know if anybody had this problem or knows what it could be. Friend of mine thinks its a heat shield but before i take the skid plate off and look around want to hear from you guys.
Thanks in advance for any help!

Is your truck a 4X4? If so, it could be your IWE's going out.

Grinding and rattling are very different sounds to my ears. In regards to Elmore's post, if you have a 4wd truck, engage 4wd and see if the noise persists or goes away. That will be your indication as to it being an IWE issue or something else.

it is RWD not 4x4. And it sounds like metal rubbing on metal. this is almost exactly what i hear

Sounds to be one of two unrelated things. Could be your flexplate or started teeth not aligned properly. Or it sounds like you lost a timing chain guide bolt and something is loose causing it to chatter or scrap when more load is put on it. If that's what happens when you give it gas at 1500 rpm you should really not be driving it. Unless you have a warranty that is

That was my feeling. I have 13xxx miles on my truck and brought it into ford and the tech told me "you know a lot is happening at low RPMs i don't hear anything." so i have it in writing exactly what he said with the date and all of that so if something happens then it will be a good time. You think there is any chance it is the exhaust shield? friends dad said thats what he thinks but dont want to start removing things to find out its not that

You would really be able to easily pinpoint the noise if it was a heat shield. There are not very many, so you can run around quick and grab one by hand to see if it stops

I'm thinking exhaust rattle somewhere. I would get someone to hold the rpms at the speed it makes the sound, while someone else has a look/hear under the truck.

Could one of the cats be broken or loose internally?

 

[chargerCHAD]

I have tried just revving but it only happens when in drive/reverse. No abnormal noises at all in park/neutral. I finally got the recall notice for my master cylinder so the truck is in the shop getting that replaced and i'm having them look at the sound also. I got the tech to hear it and he said it might take a few days to figure out sadly. ill let you guys know what they say when i get the truck back

OP did you ever find out what this was. I am having the same issue!

 

[Rougen123]

Sounded like an exhaust resonance rattle to me...

 

[tpbesone]

Did you ever find out what the cause of the rattle was. I have a '15 Screw 3.5 EB and have the same rattle as the video at around 1,000 rpms.

I love it when people don't update their threads.... NOT

That really sounds like a heat shield resonance. Brake shield maybe. loose turbo waste-gate nuts. I would drive the truck up against a solid wall so there is no way it can move, have a helper push hard on the brakes and put it in drive. Get the rpms up to where it resonates and crawl under to find the issue.

My 2013 f150 4x4 5.0 (160,000 KM) does exactly the same thing at about the same rpm. So it is not an ecoboost issue. I had the water pump and belts and idlers done 6 months ago so I doubt it is belt or pump related (the pump going was a different sound). Any update on this would be greatly appreciated.

Fixed. There is a small heat shield on the exhaust crossover pipe just aft of the transmission pan. It is held on with two pinch type bands. One band was long gone and the other was still there but broken (rusted). A pair of 36 mm stainless screw type band clamps and the issue is gone.
