The other thing to note is that I wasn't experiencing sway exactly, but more of a general instability. Like even a passing SUV would push me around, and a Semi was VERY annoying. The truck has 4 brand new GoodYear Wranglers that match original equipment for the truck, and they are properly inflated, yet it more felt like I was towing with 4 nearly flat tires. Still, the trip home from the dealer seemed a LOT better. Is it possible that the active sway is now working properly in the truck? I purchased the truck a bit over a month ago and it came off the 3 year lease with only 30k miles, and it was clearly well cared for.
