wierd noise

[Steveyfz450]

Hi I have an 06 f350 psd with farmboy turbo back and sct with dj's tunes. For about 2 months I have been having this wierd noise like a loud shuttering sound under the driver floor. It only does it from a dead stop when I get on it and then right back off . Now with the trailer I am getting this wierd like clunk sound in the same area when I come to stop from high speeds. Does this sound familiar to anyone, any one have the same problem if so the truck is only a year old and has 16,000 miles on it would this be covered under warranty ,any info would be great.

Sounds like your exhaust clamps need to be tightened for the shuttering. The clunk sounds it might be your exhaust down pipe against your EGR cooler up-pipe or exhaust clamp rubbing against the frame.

Carlson is right tha happened to me but check your motor mounts if they are loose or broken it will exaserbate the problem if you look under your truck you should see worn pipe right near the joint good luck!

.. doesnt really apply but i tried to take my toyota corolla a little offroad and bent the Shnit out of my exhaust. it made that sound. i fixed it with some upside down hammer action.
