NHTSA Complaint #11507205 — 2019 FORD F-350

experiencing intermittent violent wobble of front suspension/steering. 2 significant events since October 2022. Traveling at highway speed and incurring rough road steering wheel wobbles severally. Only way to stop it is to slow down below approximately 50 mph, however latest event (02/14/23), had to go below 20 mph to get it to stop. very dangerous on the highway. Tractor trailer had to change lanes very quickly to avoid hitting me. Ford dealership is aware of the issue, however they only offer a new steering dampener that has not been available for almost 4 months. Had an independent service center look at the suspension. They found that the dampener is faulty and another suspension joint is showing premature wear.
