I have a 2001 Dakota and it is making a noise from behind the cab somewhere that sounds like I'm dragging my muffler (metal on the road sound) or something rattling under the bed. Nothing is dragging back there though. The sound gets faster asI drive faster and happens mostly as I accelerate or hit a bump. Applying the brakes or putting the transmission in neutral does not stop the sound. The sound is not consistent either. I took the drums off the rear wheels yesterday and nothing came out that would indicate an object rolling around in the brakes. I also tried to shake or turn the prop shaft and that was very solid.
Any suggestions?
