I have a 2002 ram 2500 4x4 with the cummins never new about the death wobble. I bought a new 2019 ram 3500 mega cab dually limited 4x4 with the cummins I have less than 5000 miles on it and found out what the death wobble is today. Also found out this issue has been around for years. Taking truck to dealer next week going to give the service manager a ride if he's brave enough. love the truck but don't care for this option that came with it. Will be driving the 02 ram again hopefully its not contagious and hopefully the dealer can fix it.
