2005 4.7L 125,000 Miles. I had exact same noise. It was the Exhaust Manifold gasket (according to BIG-O); they replaced and now no noise.

 

If you get any backfiring under acceleration, could also be a broken valve spring. I keep reading it's a common complaint for durangos in this age and mile range.

 

I had a noise when accelerating, sounding like a loose heat shield. After reading this thread I checked the drives shafts for play, then the exhaust pipe by beating it with my hand. Fallowed the noise checking everything to the engine and found a exhaust pipe heat shield under the front drive shaft was loose.

 

I am having this same issue does anyone know what it is I have a 2007 darango 4.7 v8 all time 4x4

 

You're in the wrong forum for a 2007. None of us own 2007 AWD Durangos.
I'll give you my thoughts anyways, check your U-Joints. Check your CV joints on the front axle shafts especially if this noise is more pronounced around a turn. Otherwise you likely have a CV style front driveshaft and that could be causing the noise when the drivetrain is under more stress as you accelerate.
Check your front driveshaft, is it a CV style joint on the front driveshaft?

Same deal here. I can really hear it from a dead stop to roughly 35mph then engine/wind noise cancel it out BUT yes bbcard in a bike spoke is exactly the sound or the bigwheels back in the day that had that sound too (if Santa installed it of course). I will be checking the manifold soon anyway I'm guessing it's more of that being loose than anything else.

Side note, does anyone ever get a big thunk when letting off the accelerator? Probably a loose cv joint or ujoint right? I had the front diff "referbished" already with a big chunk of the front end parts but of course the mechanic never mentioned a word about other possible issues 🙄 😒

 

My truck now at 230k miles. I had same issue just a couple months ago. Turns out to be a very small exhaust leak from oem exhaust manifold gasket. The pinging will disappear at times after engine warms up. at times more noticable when cold which makes sense. As time goes buy, hole eventually grows and then it was obvious it was exhaust leak.

Had gasket replaced and all is quiet.

 

It seems to stop the faster I get but anyway my Durango is a 2016 SXT model I have attached a snippet of the sound, any help would be great. Also it does not throw off any error codes at all

 

Where is your sound file?

 

I keep trying to add it but I have no clue why it will not post I’m going to try it again. Please let me know if it attaches thanks
