Rattle from Under my Truck

[CChinman]

I have a '03 3500 long box and I have a very noticeable rattle sound coming from under the truck. I have looked beneath and it appears the forward passenger side attach point for what must be a heat shield is hanging loose. Has anyone else experienced such a rattle.



Aside from what appears to be some fluid being thrown around under the truck as well I noticed nothing else that could be making the noise.



Looking for some insight as to where else to look for the noise, has anyone had a heat blanket come loose and make this noise etc?



It only happens when the truck is in motion, not while idling, the truck has to be in motion.



Thanks,

Chris

You should tighten it and see if the noise goes away

I was going to but the blanket is secured to the truck via fasteners and there is not one in the corner that is loose. Nor does it look like there ever was one. I will check again.

6spd??

Could be the clutch disc rattling... mine does it and its progressively getting worse...
