i have a 2005 f150 lariat and when its in gear and just above idle rpm while going down the road. it has a chatter almost sounds like a metal chatter from under the hood. doesnt happen when at a idle while rolling, only while above idle rpm. doesnt do this when in part or in gear and not moving. any help would be greatly appreciated.

 

Mine does the same thing. I'm assuming it might be the timing chains, or possibly an exhaust leak. Hopefully someone else chimes in with some good info.

 

Loose exhaust heat shield?

1. Stop truck.
2. Open passenger door.
3. Throw wife out of truck.
4. Close door.
5. Continue driving.

 

Does it make the noise in park just above idle? Mine will make a lot of noise around 1000rpm in park or not, and I have been told it's the cam phasers and its normal.

 

After taking my Truck to a shop to check out the front end chatter it turns out to be the four wheel drive actuators are shot. Which means they aren't fully disengaged. Just letting you allknow what it turned out being
