so ive had this noise for a while, ive been keeping up with the other clunking/rattling/banging posts, none of these describe mine.

it happens only under normal acceleration from a dead stop about 65% of the time. its a slight binding/rattling sound. i thought maybe exhaust pipe rattle, banging on sumthing, but i cant find any wear spots underneath. i do have a lift, but cannot remember if i had it before or after the lift was done. anyone else hear this?

 

At one point of time I was hearing stuff too until I remembered that I had something in the bed of my truck... could be something underneath the seats or in the storage bins. It could be simplier than you think.

 

I found a four month old "soda" in my floor storage bin. Same problem as yours and when I stopped too.

 

I gotta ask: How did you know it was four months old??????

 

I have the same sound when I take off from an dead stop. More often I hear it when turning.

 

Maybe exhaust manifold bolt recall. This could be your problem. There was a recall for the '09 rams.

Lol I used to hate this advice, but it does work...

 

 

It was from tailgating last football season. Steelers beat Ravens. Found it about four months later. Didn't check the "born on date" but figured it was skunky after freezing and thawing all winter.
