I lost control of my F350 when I was at 50 MPH. It started to shake uncontrollably when I hit a bump in the road⦠I tried to break and it got worse.. so I took my foot off the gas, ended up of the side of the road. I called back to our mechanic and he said it was safe to drive under 40 MPH. (He looked up the problem and found all the related incidents with the f series trucksâ¦) Since then the have replaced the parts that Ford said to replace⦠and the truck is still up drivable.
