Noise on slowing down, clunk, then it goes away?

[realtree250]

ok completely lost on this one truck does great most of the time but it seems like this only happens when driving above 40 for a while and then comming down an incline. i hear a noise that actually sounds like its comming from the left side of the truck to the rear (trans or rear end) sounds like a buzz, kind of baseball card in the bicycle tire but also a little like a bunch of bb's rolling around then you come below about 10 mph and something makes a clunk noise and its gone. . . any ideas?

i dont think thats it but who knows. . . got the wrench light taken care of, the pedal they put in wasent calibrated to my pcm and the wires above the connection were chafed from my boot rubbing on them. so hopefully thats taken care of . . . is it possible that that code could have cause somethin a little weird in the transmission or rearend to make this noise? i dont have much longer on my warranty so i need to make sure this gets resolved. . . thanks guys
