Last year when it was very cold out my truck would make this horendous noise but only occationally and in short bursts.
Well this year it has started already and the bursts are more frequent and last longer. I've held of posting a question because I was having a hard time coming up with any kind of description of the noise. The best that I've come up with is that of a zipper on a camping tent only deeper in tone and a lot louder. When it happens I can feel the vibrations on my left foot but not in the steering wheel. Last episode was almost half a minute in duration and I was able to shift into Neutral and rev the engine to rule anything there out. Speeding up has seemed to help stop it and it only manifests itself when driving down a flat road under constant speed and and little power, almost coasting along.
Thanks for any help
Rick
