NHTSA Complaint #11616521 — 2015 FORD F-350

Hello on 8/3/22 I was driving on the highway and as I was accelerating at around 50mph the steering wheel started to violently shake back and forth. I thought I was going to loose control and crash. I have never experienced this in a vehicle before. To date I have replaced most of the front components and within the past month, both front Tie rods left and right. Steering tie rod including steering gearbox tie rod were replaced. My tires have been replaced in July of 2022. Both front Hubs in 2023. I just had the tires rebalanced again two weeks ago to try anything. The ball joints in 2022 and the mechanic says all these parts above are ok and he cant diagnose anything to cause this death wobble which he experienced. I am now having another shop replace the front Track bar to see if that helps. In the past two years I have spent several thousand dollars on this trucks with front end parts and I still experience this steering shake and wobble. Two years ago at that time the truck was about seven years old, I took it to the ford dealer and they advised that they couldn't find anything and trucks "Do need maintenance" typical run around from ford. Can someone please help.
