    About three weeks ago, I traded my 1500 in on a 2019 Ram 2500 Tradesman with the 6.4 Hemi. From the day I took delivery, there was a clunk/rattle sound that was frequent and annoying. Can't really hear it unless the windows are up. Seems to happen on rough patches of road. This is not a small rattle, a squeak, a hum, drone or anything like that. Just a clunky rattle that happens on washboard style streets. It happens when I'm not towing anything and it happens when I'm towing my boat, which is about 4,500 pounds trailer weight.

    I've had it back to the dealer twice. First time, the service tech who was going to work on it rode with me and said he heard it. He said it was likely coming from behind the dash. I disagreed, saying I couldn't imagine anything back there heavy enough to make that kind of clunk/rattle. He disassembled the dash and secured some things back there and gave me the truck back. A freeway on-ramp two blocks from the dealership is rough. I immediately heard the rattle when running over the bumps. I called to get it back in, but had to go out two weeks to get another appointment.

    I took it in and dropped it off two weeks later and they gave me a rental car to use so they could investigate. They had the truck for four days, each day saying they were troubleshooting it via "process of elimination" and had not identified the problem yet. On the fourth day, the service writer called and said they had opened a Star case on it. He said the engineers had suggested a computer flash or the "noise reduction module" they should try that may correct the problem. Two hours later, they called to say my truck was done.

    I went to pick it up and they showed me a TSB for a drone/hum/booming problem in the cab of some 2500's that is supposedly fixed by this computer flash. None of the problems listed was even close to what I have reported. They told me everything under the truck was "perfect" and to drive it and see if the problem is fixed. It does not seem likely to me that a computer flash would fix this.

    I asked for the Star case number, but was not provided with that. I asked for the itemized list from their service department on what had been checked, retorqued, etc. but didn't get that either. I took the truck and left - you guessed it - the rattle was there unabated as I hit the freeway ramp two blocks from the dealership. No way they could have test driven it and not heard the rattle after the flash was done.

    I drove it over the weekend and think the following things may be true. It seems to occur when the right rear wheel hits the rough spots, but not so much when the front wheels or the left rear (driver side) wheel hits. At times, I operated the truck in Gear Limit mode because this works best driving in town. I didn't seem to hear the rattle as much when in this mode, but still can't be sure about that one. Does this make any sense to anyone?

    My truck was built in March, 2019. I started noticing the clunk/rattle right away when I bought it in July. It now has 1200 miles on it and it still rattles. Even my girlfriend can hear it and she knows nothing about cars or trucks. Several of my buddies have admired the truck and then asked what the rattle was when I gave them a ride.

    I love everything else about the truck, but this problem is really taking the enjoyment out of buying a new heavy duty towing beast of a truck. Has anyone else heard of this or experienced it? Any advice or suggestions for me going forward? I intend to call the service manager to get the Star case number and the service records I asked for but didn't get.

    If it was me. And I know it sucks to say this cause it’s a brand new truck. I’d crawl under it and tighten EVERYTHING. Sure sounds as if something is loose. Shock, sway bar, track bar, everything that can be tightened I’d touch it.

    Had a dissimilar issue with a 2016 Tradesman that had a slow speed clunk up front that could be felt through the floorboards when going over large bumps at an angle in the road. The dealer tech kept the truck a full day while I had a loaner. Tech would up loosening up numerous front end suspension components to let the components go back to a natural "set", then realigned and torqued everything back to specs. Never had the low speed clunk or any other noise thereafter. Know this likely isn't exactly the same as your issue if you are hearing a "rattle" instead, but still might be something to mention to service writer. Good luck and let us know how you come out.

    Thanks Lee. I had read about that issue and mentioned it to the techs. Mine doesn't seem to be only when on an incline, in a "bind" or when turning left ot right. Happens on any sustained piece of rough road. I thought it might be the exhaust system rebounding and hitting against something but they reportedly checked that. I have crawled under the whole length of the truck and pulled and shook everything I could reach. Not exactly scientific but didn't notice anything obvious. I told the dealer service guys it seemed like they could have checked and re-torqued every nut and bolt under the truck in four days! I'll be taking it back in, mostly because I don't have the tools or skill set to do all that. Thanks for responding. I'll post about hope it all works out.

    Yeah it definitely sucks. I agree with you though. I did tell the service guys that it seemed they could have checked and re torqued every nut and bolt under the truck in four days! I'll keep taking it back, mainly because I don't have the tools or skill set to get this right on my own. Thanks for responding.

    The 2 1/2” hitch was the cause of mine. If I leave the receiver in it will clunk over bumps and sound like it’s coming from the front end. Also, if I try I can make it clunk going in and out of 4 cyl mode

    Yes, that's true about the hitch adapter. I don't leave my hitch or the adapter in when I'm not trailering. The clunk/ rattle happens without the hitch adapter or hitch in the receiver, so I've eliminated that. Thanks for responding.

    I had a rattle in my ‘18. It turned out to be one of the body mounts. They seemed to be tight but they were not properly torqued. I used my torque wrench to tighten them to, I believe, 80 ft lbs. The rattle went away and did not come back while I had the truck.
