NHTSA Complaint #11330343 — 2019 RAM 2500

HAVING VIBRATION ISSUES IN REAR END NOT CAUSED BY TIRE BALANCE(3 NEW SETS OF 4 TIRES IN UNDER 5000 MILES). NOTICED U-JOINTS HAVE NO VISIBLE MEANS OF HOLDING THEM IN PLACE. WAS TOLD THEY ARE HELD BY INJECTED PLASTIC ALTHOUGH THEY HAVE GROOVES FOR SNAP RINGS TO HOLD THEM IN PLACE. APPEARS ONE OF U-JOINT CAPS HAS MOVED SLIGHTLY OUT CAUSING VIBRATIONS AT HIGHER SPEEDS. UPON EXAMINING SEVERAL 2020 THREE QUARTER TON PICKUPS, RAM IS THE ONLY ONE NOT USING SNAP RINGS TO HOLD U-JOINTS IN PLACE. THIS IS NOT A SAFE WAY TO BE HOLDING A CRITICAL DRIVE TRAIN COMPONENT IN PLACE. THIS VIBRATION HAPPENS AT 45 MPH AND HIGHER ON DIFFERENT TYPES OF PAVEMENT...THIS IS SOMETHING OTHER THAN YOUR EMPTY PICKUP ROUGH RIDE. IT SOMETIMES WILL GO AWAY WHEN I HIT THE ACCELERATOR OR SLOW TO UNDER 45MPH. 4 PICS INCLUDED SHOW CAP 1 MOVED OUT SLIGHTLY SO SNAP RING CAN'T BE INSTALLED COMPARED TO OTHER 3(THIS IS MORE THAN LIKELY THE PROBLEM). PIC 5 SHOWS DEALER SAYING NOTHING IS WRONG EVEN THOUGH YOU CAN SEE CLEARLY CAP HAS MOVED OUT OF PLACE IN ONLY 5200 MILES. HAVE MORE PICTURES SHOWING THIS CAP LEAKING GREASE TOO. DEALER SAID UNABLE TO DUPLICATE IN 4 MILES OF DRIVING. THAT'S NOT ENOUGH AND MORE THAN LIKELY NOT ON HIGHWAY AT SPEED LONG ENOUGH TO MAKE THIS VIBRATION HAPPEN. THAT CAP MOVED OUT LIKE IT HAS WILL CAUSE VIBRATIONS AS THE DRIVE SHAFT IS SPINNING CLOSE TO 250MPH OR MORE WHILE DRIVING AT 70MPH. *TR
