HI I'm new here and new to the deisal world and cummins.
i just bought a 2007 2500 5.9 it has about 700kms on it so far, well everytime i start the truck up and let it run/drive about 5 mins into it, i get this Clunk noise from the passenger side, and then doesnt happen again, pretty much happens everytime, when im into 5 mins of the truck running/driving, if anyone could help me that would be great, last thing i want is to bring it back into the dealership and lose work time,
thanks
dan

 

Do you drive on gravel? Sometimes gravel will fly out of the tires and make a clunk sound.

no gravel just in town stuff ,its weird i dont feel the clunk but u can clearly hear it,

 

I get the same thing. I don't know if its a flap in the heating sysem or what. That's where it sounds like to me.

 

WOW te search is working today. https://dodgeforum.com/m_684657/tm.htm

 

it doesnt seem like its coming from the dash more like under truck in the right side,

 

clucks are usually ball joints. If you jacked up the wheels and try to wiggle them, there should be no play... if there is, you need ball joints. Also check the trailing arms to make sure they're tight.

I know your truck is pretty new but, the ball joints are known for going bad. Dodge has always has problems with their front ends.

 

Mine sounds like right behind the right front tire under the floor

 

^^^^^^^same sound i have im prety sure its not ball joints the thing has 700kms

 

don't be fooled by your mileage. I've seen many posts from people that have lost injectors with less mileage. Ball joints too. In fact, it's well known that our trucks come from the factory with very low differental fluid. Dealers are suppose to check all that when they get the trucks but, not all do. Mine was half of what it should have had and it was the worse looking gear lube you'd ever seen.

The best thing you can do it to lift the front of the truck up and start wiggling everything. If somethings lose... you'll know it.
