On occassion I have experienced a strange sound and thud, kinda like a dampner closing or the compressor comming on only I don't think it is either of the two.

It occurs when I come to a stop after downshifting and/or coasting to a stop. A few 1-2 seconds after wheels stop, the sound and "thud" occur.

Anyone have any ideas??

I have the auto tranny...

The 5" with the juice rocks...I have some smoke at idle and when I get on it but I like the fuel mpg increase and I like the sound...I left the straight through muffler on there and I like the sound...Stainless Steel was the way to go, no doubt about that!

mine does that when I decel with the exh. brake on only. IT is the brake and the downshift of the tranny. It sounds like a thud.

I also occasionally get the thud, and so does my buddy with his 07 5.9 - although his is worse and more frequent
