What is your question?
when truck is idling, i here a rattling noise( almost like something rattling inside a hubcap but not quite as loud) on and off. when accelerating from a stand still it rattles a little more and cannot really be heard at normal driving speeds(45-65 mph)

You didn't say where the noise is heard, under the hood or under the truck, front or rear. If under the truck, possibly the catalytic converter has come apart and rattling. Under the hood maybe the belt tensioner or the harmonic balancer is loose? Just guessing.
Mine is currently doing the same thing, on mine however it's the spot welds have come loose on the heat shield of the mufffler. I found out by letting it idle and taking a pipe and touching points on the muffler where the welds were and then it stopped. Try that.
