Something wrong underneath truck when in Drive.

[Thrasher645]

Hey what up everybody I wanted to see if you guys could help me out. I have this vibration,rumbling,clanky noise happening underneath my truck when I'm in Drive and only in Drive. It seems to get especially loud when I'm at a complete stop. Do any of you guys know what this could be or has this ever happened to any of you?

Is it when you are driving, or stopped, or both?

Basically both. I can hear it while I'm about to stop and then when I'm at a complete stop it gets louder with a lil more vibrations and noise.

Its hard to say from your description but I would be looking for a loose heat shield or something. They can make some pretty weird sounds when they come loose.
