Anyone else having/or have had this problem?

Going down the interstate one day (approx. 80 mph) when truck started bucking like a bronc and was coming off the pavement. Steering wheel vibrating, truck bouncing up and down, almost lost control of vehicle. Pulled off road and checked drivetrain, tires, brakes, lug nuts, etc. Got back in and continued to house. Has happened two more times, both times at 75 mph. Vibration was so bad it popped the window open on the bed topper. Semi driver next to me thought he was going to see an accident and he slammed on his brakes to get away. There has been a growling noise in the front end that has gotten worse over the last few months. The vibration can be felt in my foot through the accelerator pedal, and in my rear end because vibration is coming up through seat.

In last two years, I have replaced all four wheel bearings, four rotors, brakes pads, transmission valve body, rear main seal (which still leaks). On the way back to Wyoming from Oklahoma, the truck had a horrific vibration. We made it home and took the truck to our mechanic. Four of six u-joints were out. I told mechanic to replace all u-joints while he was under the truck. Had to use a torch to cut them out as they had gotten so hot they welded themselves together. The short flex shaft was bent so he replaced that also. I am wondering if the flex shaft is bent again and this is what's causing the vibration? The growling might be coming from the 4-wheel transfer case. Could be why the rear main is leaking again. Any ideas or help appreciated, short of setting fire to this lemon.

Almost $5000 into this, and I use to own a repair shop, and this is still not a totally fixable problem and 100% due to engineering. Individual drivetrain and front end components, 100% new and balanced, new tires, multiple sets u-joints and balances, at least 4 alignments, and now another new drive shaft, 2 dealers, a very well respected drive line company, a high end diesel shop and the mechanic now is trying to balance this dynamic drive train with a damn pipe clamp. The drive line dynamics or angularities are out when all parts running together....kind of have to be to be able to drive.

We have owned this truck since new and planned on keeping until the wheels came off since it is a $40,000! Damn dollar truck, not to mention the repairs..... We use and rely on this truck to carry my entire family and a trailer 4230 miles one direction from our home in Galveston Tx to our home in Fairbanks Ak... You know, driving through Yukon and areas with 100s of miles of nothing and no cell service. And the best fix is having to pull out my front drive shaft to roll hwy speeds. But get to bad roads I have to stop, install drive shaft, and then stop and remove again, an endless number of times to get home. Totally rotten, totally disgusts me about Dodge and I use to own a small fleet of them and recommend them to customers.....never again. They are about to lose a loyal customer with a lot of opinions and ears to listen to my rants. I feel let down. This is not how you continue brand loyalty at all....
