Our truck experienced a severe, violent wobble that started after traveling over a uneven spot on the road. We feared for our lives as this occurred while passing another truck on a bridge with heavy traffic behind us. The shaking and wobble continued for about 20 seconds, and did not stop until the truck slowed down to about 40 miles an hour. All our tires have been recommended and installed at the Ford dealership. I maintain tire pressures as indicated on door jam. 75 lb on front and 60 lb on rear tires. There are no aftermarket modifications on our truck. I consider this issue very dangerous, and wonder how many folks may have been injured or killed as a result of their truck suddenly becoming uncontrollable, as ours did.

Bought truck used with approximately 35,000 miles. Driving down the road from 45 to 55 the front suspension gets a terrible shimmy. When this occurs, its hard to handle the truck. The front end shakes violantly. A dangerous situation since I am normally pulling a race car with this truck. Truck is not a daily driver. It's average use is 4 to 6 times per month. In order to get the shimmy to stop, sometimes I can slow down below 40 mph. Otherwise, I have to stop. It may or may not go away. The strange thing is that it does not always do this. The truck has new shocks, new tires, balanced, and aligned. Tires are approved for the truck. The shimmy has become more frequent and is prematurly wearing the tires. Tires are inflated properly for use of the vehicle. Problem has recently started within the last 6 to 7 months. Mileage is currently 78,490. Therefore shimmy started at approximately 75, 000 miles.

Upon driving at highway posted speed, I encountered a bump in the road while in a turn. Upon hitting the bump, it sent my front-end into a violent speed-wobble which almost put my family and I into the retaining wall. Being that I'm a former state police officer, I may have "saved" us only by being highly trained within driving and vehicle control. I have read forums with many stating that they have experienced the same flaw, some with not very god endings.

This vehicle since new has had numerous incidents with a severe uncontrollable shimmy in front end and steering wheel.I have had it to the dealer numerous times and they tell me there is nothing wrong with it. Ford has sent a few notifications stating that they are aware of the problem, but that it is just caused from improper inflation.I have set the tires to manufacturers recommended psi weekly, and doesn't make a bit of difference.Ford is closing their eyes on this one, and it is going to cost lives!!!.when this occurs you have absolutely no control of the vehicle.another problem with this vehicle is the engine is junk. My vehicle has 43000 miles currently, and has had the motor taken out of it twice already for repairs!!!,and has been to dealer at least 6 or 7 times.I own a small tree care company and really cant afford a $45000 mistake to a multi billion dollar company.

2006 F-350 lariat Super Duty- in March while driving on I-70 I hit a bump in the road at 65mph and the front end and steering wheel shook violently and I was immediately thrown into the passing lane. I took the truck to summit Ford in silverthorne, co where they called my description the "death wobble" and they replaced the track bar, ball joint and steering dampener. I felt fortunate that no traffic was near me and I survived the uncontrollable event! now with the $600 "repair" expense I left the service center satisfied that I would be safe on the road. Two weeks ago while on a trip, the same "death wobble" happened again and I was out of control and in the other lane again, thankfully no traffic was beside me or oncoming which would have caused an accident. So now I have lost all confidence in the safety of my truck and drove conservatively to get home avoiding all bumps and slowing dramatically when approaching any imperfect road surfaces. Even with my new cautious approach to driving the "death wobble" happened again at only 50mph. I have since discovered numerous complaints and you-tube videos of others with the same problem as well as complaints on the National Highway Traffic Safety Administration's website. I have found 2 documents issued by Ford Motor Company regarding this problem, a technical service bulletin 04-26-1, and a letter dated April 2009 (literature program 09L02) addressed to [xxx] regarding "shimmy, a severe vibration and oscillation in the steering wheel...........". I am running the truck at the label specified tire pressure and there are no suspension modifications. I am considering replacing the F-350 with another vehicle that I can be assured of not having this problem. My question to Ford is, what am I supposed to do now?

2006 Ford F350 experience extremely violent shaking when driving 45 plus mph and hit any type bump. Shaking is so violent steering is not capable and braking only makes shaking worse. I've contacted dealer and they said they replaced a bushing but problem persisted. They have not corrected the problem. Vehicle is basically out of control when this happens. Last date of occurrence is July 14,2011 and this problem has persisted since truck was purchased new from dealer. Truck has no lift and is stock model. Please help!

Ford F350 death shake has happened multiple times truck hits bump or pot hole regardless of speed (but shake is worse over 40 mph)and starts a very dangerous shake that gets worse until the whole truck is out of control. Braking hard to stop will stop it but accident seems to be around the corner. I have taken to dealer and tire shop they say nothing wrong.

This is a company vehicle driven by several different employees. Many of these drivers have complained of a sudden violent shaking of the vehicle while at highway speeds, usually after hitting a bump in the road, expansion joint, etc. This shaking will only stop by lowering speed sometimes to as low as 10 mph. We have taken the vehicle to a local Ford dealership multiple times with no success in solving the problem. They even advised us to install airbags to the rear suspension to distribute weight to the front of the vehicle when loaded. We are currently on our fourth set of quality E-rated tires (recommended tire pressure is maintained) but are still experiencing the problem.

1. traveling at 65 mph hitting a bump in the road 2. front axle begins oscillating with such violence that control of the truck is difficult until slowed down, the entire vehicle shakes to the point you feel it will come apart. I was traveling on a highway when I experienced this. I nearly caused an accident. I'm terrified when this will happen on a icy road. Someone is going to get killed. 3. nothing. Apparently there is no fix as it is unknown. Ford is aware of the problem but refuses to be held responsible. Vehicle information: " 2006 ? Ford ? F350 ?? entire front suspension component ?

Excessive front end shimmy on occasion with my Ford F350 4X4. I have received a letter from Ford discussing this issue. The first time the problem occurred, my tire pressure was low and subsequently maintaining proper tire pressure seemed to prevent the problem for a while. However, recently I hit some bumps while traveling on the highway at a speed of approximately 65 mph and the front end began to shimmy very violently. I knew to hit the brakes to regain control of the steering, but I had to stay on my brakes until I slowed to approximately 40 mph before I could regain control of the steering wheel. I called a local Ford service center, but they said they would "only be guessing" at the proper way to fix the problem. I then called Ford customer service to discuss the issue, as I am nervous about riding on the highway with the vehicle. They suggested that I call several service centers until I find one that has experience with trying to fix this particular problem. I have done that and I have made an appointment for service tomorrow. The reason for my writing this complaint is that the last occurring was so severe, that I was afraid of causing an accident due to the quick deceleration I was forced into in order to regain steering control of the vehicle.

When traveling down the freeway a bridge deck or pot hole will cause my 06 F-350 to shimmy uncontrollably. This has happened about a dozen times. I have to come to a complete stop to get the truck to stop shaking. Ford says there isn't anything wrong with the truck.

- Mt. Gilead, OH, USA

The front end of my 2006 F-350 will shake when going over a bump at speeds of +65 mph. It is almost uncontrollable. I have taken it to Ford and they say there isn't anything wrong, this has happened 6 times. I have checked numerous web-sites and there are at least 500 other complaints on this subject. It is a danger to me and all the other motorists around me.
