On bumpy roads I can hear a noise like a thud coming from under the truck. It kind of sounds like a cable or something is slapping on something. I have looked and can't seem to find anything that is loose. Has anyone had this problem? Thanks.

What kind of truck do you have? Fill out the sig and maybe we can help..

 

could be the center bearing when mine went out it started like a rattling than after a while it became a loud thud
