I have experienced the "Death Wobble" numerous times. I have spent thousands of dollars since owning the truck chasing whatever we thought might be the issue. Ball joints, steering damper, tie rods/end, track bar, stabilizer bar, tires, the list is long. Stops for a time then starts up again. Death wobble consists of speeds over 60 mph and hitting bump and wheels wobble uncontrollably. This causes immediately slowing down until the wobble stops, however it is a violent shake and can pull the truck. Vehicles behind have no notice at immediate deceleration. Has not happen in the rain thank goodness.

2014 Ford F350 Super Duty Platinum 4x4 Diesel: Steering wheel started with small vibrations (90,000 miles), had Ford tell us that we needed a new track bar and bushing, so replaced it. Still having small vibrations in the 45-60 mph range. Then Ford said tie rod ends could be causing the problem did have some movement in the drag link, so replaced those, still having vibration. Had sound and clunking coming from steering box, so installed new steering box and pitman arm, and the small vibration has morphed into serious death wobble, and the pickup becomes almost uncontrollable until slowing down to under 45mph. Replaced all 4 shocks and the steering stabilizer. Sadly, the Ford dealership doesn't really seem to want to acknowledge there is a problem and work to fix it, and yet a quick internet search becomes extremely distressing quickly. To think, that you (NTSB) and Ford is likely going to wait until there is an accident before owning up to the fact that this is problematic and should be dealt with appropriately. They have offered to replace the steering stabilizer for 2017 or newer, even though they know it affects models as early as 2005. Clearly, neither you (NTSB) or Ford care about the people, it's just all about the dollar and CYA (Cover your [XXX]).

This isn't a safety concern, but many Ford 6.7 liter diesels have an issue where 2 of the bottom bolts that hold the vacuum pump were never tightened properly in the factory and it's causing oil leaks. I bought the truck used in 2018

While driving at highway speeds and driving over bumps or uneven surfaces the vehicle begins to shake uncontrollably. It feels like the whole front end of the vehicle is coming apart. It makes controlling the vehicle extremely difficult. I almost hit several vehicles that were on the highway with me putting many people in danger of injury or death. This -??Death Wobble-?? has occurred several times starting last year (2020 November). I had to wait until I could save the money to have the problem fixed. It was quite expensive and with Covid and my reduced income it took some time. When I took it to the dealership service center to have it fixed one of the technicians went on a ride along wanting to see it the Death Wobble happened. It happened very quickly once the vehicle reached 65 mph. The technicians response -??Oh! That-??s a bad one! There were no prior warnings or lamps to alert of the issue.

Death wobble- horrible shake to vehicle

When driving down the highway interstate 25 in Colorado. Traveling approximately 75 mph. I experienced severe vibration in the front end of the truck. Vibration would not go away until I slowed to almost a complete stop. This only happened after I hit a bump on the highway causing the front end to start vibrating and it progressively got worse. I recently had two of my tire rods changed new brakes put on the truck in my tires rotated and properly inflated. These cannot be causing the problem there must be something else happening.

Any time I'm over 60mph and hit a bump or bridge joint the whole truck wobbles dangerously and have to hit the brakes slow down and pull off the side of the road. This has caused me to almost be in a car accident multiple times endangering me, my family, and other drivers on the road. I've taken it in multiple times to the shop and they can't figure out what the issue is. My truck is stock and has never been in an accident before. I have gotten new tires, brakes, and rotors in the process of trying to fix the death wobble and nothing has fixed the problem. I went online and have found multiple people that have experienced the same problem.
