Steering Tie Rod Assembly problems of the 2018 Ford F-250

The truck had the death wobble when I hit a rough patch on the highway and I had to slam on my brakes to get it to stop. Luckily there were no vehicles right behind me or they would of hit me. This happened at a large bridge over a river. I had a Ford dealership get the truck and try to repair it using TSB # 18-2268. I received the truck afterwards and drove it on the highway again and it started to shutter at highway speeds when I hit a bump again. This would last miles before it would stop. I brought it back to the dealer and they found a loose tie rod. They are �fixing� this and I will see if this corrects it. This all happened within 2 weeks.

At around 7k miles developed a death wobble shimmy in the steering when hitting potholes or cracks in the roadway at 40 mph and up. Took into dealer and upper tie rod was replaced. Problem appeared to be somewhat less noticeable. Now at 10k miles the dw is prevalent in everyday driving and makes the vehicle very scary to drive. Almost total control is lost for several seconds until you brake hoping not to get rear ended while regaining control of the vehicle. Its bad enough to spend $60k on a truck that developed this type of issue at 7k miles but at 10k miles it's not even about money, this could kill someone. Ford has listed a TSB on this issue that I am currently looking into but I've seen no confirmation that this fixed the issue, appears to be more of a bandage. Ford needs to fix this issue ASAP.
