Did you check the small cargo are where the jack is and make sure the jack and related tools arent causing it?

You can get under the D with a light and see if the left rear shock is leaking. Take a towel and wipe it down to see if there is any oil on it.

 

Thanks for the ideas, yep I checked the jack and cargo space under floor, also checked shock for leaks everything looks ok, I talked to a local parts guy and he told me similar sounds have been corrected by installing small shock bushings.. He stated this would compress the shock slightly more with the vehicle at rest and could correct the problem without risking bottoming out, as I have no plans to jump my d r/t. I plan to to this soon I will report back

 

Dodge service manager called me yesterday and said the higher ups know about the noise and have no plans to do anything about it...... Stated they do know it's not a shock, I'm not convinced at all and I remain super pissed about this, 46,000$ sticker and a clunky rear end.

 

I also have this issue. I have taken into the dealership but of course they suggested I drive it for a while to see if the shocks break in a little. Due to other issues with my Durango I have put this issue off. The other day I looked underneath the Durango to see if my full size spare was loose or if the exhaust was rubbing off of a plastic piece as other members have suggested. Neither seemed to be an problem. While hitting and pulling on the tire I noted there was an echo type thud which was similar to clunk I am hearing inside the Durango. I am eventually going to take the spare out to see if the sound stops but I just haven't found the time to do it. Has anyone with this problem driven without their spare attached.

 

I had/have it and tighten up the spare a little and seemed to cure it 80%. might try deflating the spare a little, get the cable a bit tighter and then inflate, that will make that sucker tight.

 

This is a good idea I will take the spare out completely and see what happens and report back within the next few days

 

After chasing the notorious thump in the front end of my 2004 and 2008 I can tell you a bushing with just the little bit of clearance will produce the noise we all our hearing. You can never check for a worn bushing/excess clearance on anything but completely level ground at normal ride height.

Also the jack and its parts could be the culprit as well.

 

The problem stems from the self leveling shocks ,its like having a second set of springs no rebound at all dealer will u alot of run around

 

Mine isn't equipped with load leveling shocks. But that was a problem in another unrelated service bulletin..

 

I just had the TSB I posted completed on my D today. I will be picking it up in the AM and will let you know how she does. These load leveling shocks have been on back order for a while, so the dealer says, so lets hope they were on back order because they were "fixing" the issue.
