Check to see if one of your brackets holding the exhaust pipe has come loose. That'll make a rattling sound - especially if it towards the end by the tailpipe. When you're accelerating - more air is forced thru your exhaust at a faster rate, so it's not moving as much as when you're sitting still and the truck is just at an idle with less air/exhaust moving thru the tailpipe. If it's only making the noise while the truck is stationary & the noise stops one the truck is moving - that pretty much rules out anything to do withe the drive-train or suspension. You are sure the noise is from the back & not coming from under the hood? If under the hood - check your oil level ASAP.
if it goes away when you turn the a/c on its the a/c clutch plate that is dragging and when you turn it on its pulled into the the a/c compressor and is turning all the time that's why noise goes away,you have to replace the a/c clutch.sometimes you can try prying with a screwdriver the edge that is dragging and noise will go away.
You will need to figure out where the noise is coming from.If it does it while idling then look under the hood.Could be alternator,a/c clutch,water pump,tensioner.If it is under the hood then remove the serpentine belt and see what pulley you can`t turn by hand.Caution it could be hot.Good luck.
You are luckey it happen at idel. Open the hood and put your hand on various sheetmetal and plastic parts until the noise goes away. When you determine the piece at fault, see if some screws are missing or if it can be repositioned to avaoid the noise. Does not sound serious.
