I have a 2019 1500 crew Laramie Sport 5.7L hemi non e-torque, 11/9/18 build. Currently have about 8900 miles on it (bought it with 20 miles on it 12/23/18). I recently noticed (within the last 800 miles or so) that my truck does this "bump" "wrapping" thing when I come to a stop or take off from a stop. Basically feels like the truck stops, but the drivetrain is still going and it clunks at the end, or at take off. I had a Range Rover not long before this that developed it around 90k miles, and it was valve body related in the transmission, but this feels more like its in the rear end/drivetrain of the truck....like the truck stops and the slack hasn't been taken up between the differential/driveline/transmission. I have had the TCM software update done early on (I think released in February) to fix the shift issues, so I doubt it is software related as the only TSB I found for transmission stuff, is the same one issued in February that was completed.
Sounds like those that have taken it in either were told it is normal, or had their flange bolts re-torqued, or grease added into the driveshaft under the boot.
My concern is that this just started, and I don't want to end up damaging anything. Also, its extremely annoying in stop and go traffic as you try to feather the throttle to avoid the clunking. And since it has never done this until recently, I know its not normal, otherwise it would have done it from day 1. I had some teething issues with this truck from the beginning, and some of the issues made me question keeping it (came out of a 2015 F-150 ecoboost, which overall was pretty good with a few less teething issues), but I really like this Ram and it has been fantastic for the last 6k miles (all of my concerns were fixed early on even though it took a few tries on some of them).
I'd like to monitor this post....but also want to get my truck checked out. Just don't want to be told its normal as it is a bit of a hassle to drop it off and pick it up when they are done. Any thoughts/feedback?
