Anyone have a clunking/popping sound at slower speeds over larger bumps from somewhere in the vicinity of the "c" or passenger side rear pillar? Maybe the rear door needing an adjustment to the strike plate or I still suspect the plastic cover in between the cab and bed right above the frame. I have checked everything else. I would rather fix it myself than let the dealer do it. The tech who "looked" at it said he could not hear it. Then I took him for a ride through their parking lot and heard it clear as day. Then again the guy could not even add when he put my new oil change sticker in the window. He added 300 miles instead of 3,000.

 

I have the same rattle. Thought it was the nerf bars, but it's not. I'll be curious where this thread goes.

 

I have the same problem on my dakota.. hmmm

 

I still think it is the door and will try adjusting myself rather than letting the techs mess with it. Will also jam a shim between that plastic piece and the cab to make sure it's not that.

 

Any chance it's just the seat belt? If mine aren't sitting flat against the pillar, they'll bounce around and make a clunking noise. Sometimes they get stuck at an angle between the seat and the pillar.
