Basically stock truck with highway tires, 22k miles, and I baby it. We had some snow here, in my driveway, started it up, pushed 4x4, and about a 50 feet later, marbles in coffee can. It’s been working great and smoothly up until now. No idea why this happened. Found some folks on the facebook group with failures too, one guy said his failed at 10k miles. Wondering how widespread or if it’s a fluke. I’m familiar with the 4x4 system, I own several ram trucks, of different years, and even my plow truck, the front driveshaft went well over 100k
