When driving this truck, if you hit a pothole or any uneven surface, the truck will shake violently and it's all over the road. It takes all the strength in my body just to hold onto the steering wheel, and the only way to stop it is come almost to a complete stop. Someone's going to get killed, because when it start to shake, you have know control over the direction it's going to go. From what I've read on the net, this shake is called the death wobble and for good reasons. I also heard that Ford had known about this defect for years, but want do anything except give you the run around.

At highway speeds when making a slight left turn when encountering a bump in the road the front suspension begins shaking violently. This is commonly known as the "death wobble" for which Ford has many service bulletins. Once vehicle speed is reduced to approximately 40 mph shaking stops. The process of fixing is long and consists of trial and error until the many possible reasons are finally addressed and specific thing fixed.

When you hit a bump at a higher rate of speed it proceeds to shake so violently that you almost lose control. Research shows that an anti-wobble track bar will fix the problem. If that is the case, Ford should be responsible for fixing it. It is dangerous and a ticking time bomb. It has nothing to do with tire pressure. It is a design defect that Ford should be responsible for. A person should not spend $60,000 on a vehicle only to have to turn around and sink thousands more just to have a safe vehicle. This should be a recall and corrected by Ford. How many crashes/deaths have happened but have not been attributed to this as it has not officially been a recall issue??

Death wobble. Severe steering wheel and tires shaking on the front.

- Bay St Louis, MS, USA

We have a 2011 Ford F250 Super Duty diesel pick up with less than 20,000 miles. It is like new, but has developed a serious mechanical defect. Ford Motor Company has tried up to (11) eleven fixes for this life threatening problem with no success. None of these "fixes" apply on this pick up. Now since the pick up is older than 3 yrs. Even with such low mileage they want us to pay for "trying" out more possible fixes that have currently been unsuccessful for all these Ford F250 & F350 pick ups. This should be at the Ford Motor Company's expense. The bottom line, it should be bought back by Ford since it is not yet proven to be fixable. Problem: The "death wobble" as described on the internet. This occurs anytime these Ford Super Duty F250 or F350 diesel pickups are driven over 40mph and a bump, rough road, or pothole in the road is hit. The operator looses control of the vehicle. The first time this happened, the pickup was pulled into the on-coming traffic. It took all my son's strength to gain some control and keep from hitting an oncoming semi-truck. This vehicle is worse than the internet video as confirmed by the bend Oregon Ford dealership. Applying the brakes makes it worse. It has to be allowed to slow down on its own. The vibration is so violent it takes all ones strength to keep it on the road. It's one of the more frightening experiences you'll encounter behind the wheel. The vehicle is shaking so badly you think it'll fall apart and that you're going to die. That's why it's called death wobble.

After hitting a bump in the highway the front suspension on our 2011 Ford F250 4X4 pickup began to shake violently. I had to apply the brakes and slow down to about 40 miles per hour to get the shaking to stop. After this incident, the death wobble occurred again several times. I took the vehicle back to the Ford dealership and they replaced the track bar bushing and ball joints at a cost to me of about $400. Now 3,000 miles after the repair was done by Ford the death wobble has occurred again. The violent shaking of the front suspension and steering is a huge safety concern and could easily cause the driver to lose control of the vehicle. Also having to quickly slow the vehicle down 30 or 40 mph to get the front suspension to stop wobbling could easily cause an rear end accident leading to casualties.

Ford Super Duty F250 & F350 are well known to have the death wobble. This problem has been an issue for several years. Starting as early as 10000 miles. If the death wobble happens during a rain storm you are pretty certain to lose control of your vehicle. The front end will start shaking violently after hitting the smallest uneven surface in the road. I hear that the Dodge has a similar problem this can be googles and there will be thousands of people discussing this dangerous issue.

My husband was driving through a road construction work zone when suddenly the steering wheel started shaking violently and jumped out of his hands. He lost control of the truck. The other drivers were able to compensate for the out of control truck and an accident was avoided. I went on to research this issue. I found a forum with many others having the same issue. My husband took it to the local dealership where they say they have no knowledge of such issues. They told him it was poor tire pressure or out of alignment. My husband had both checked and there was no problem. I fear it is just a matter of time before there is a severe accident due to this issue. The others say the vehicle continues to do the" death wobble" as it has been coined online. Please have someone look into this problem. I have also emailed Ford Motor Company.

When traveling at highway speeds, if my truck hits a ridge or bump in road, it starts shaking violently up and down. I slow down and fight the wheel to get the truck to the side of the road. So far, this has happened approximately 18 times. Most of the time, it stops shaking as I slow down. Twice it stopped shaking after I crossed traffic to get to edge of road to stop. Very scary! the first time it happened, it bounced up & down so hard, it pulled the wheel out of my hands. As I gently braked to slow down, it stopped bouncing up and down, but then started up again when I hit the next expansion seam on the road. This happened about 6 times on my way to work that day. I was driving approximately 30 mph in the right lane to get to work in a 65 mph zone because I was scared to go faster. Traffic was zooming around me and honking. The vertical shaking didn't happen again for about 3 months although I traveled the same highway with the same bumps and the same speed (gritting my teeth). My mechanic examined the truck 2 days after the first round of incidents and found no problems with the front end, steering, or shocks. Nothing was loose, broken, or out of specs. I informed Ford.com about the problem and was told to take the vehicle to the dealer. All of the discussion groups said that the dealers could not fix the problem. There seems to be no recall for this incredibly frightening problem. I have always owned Ford trucks (last truck is a 1996 F250 that was a wonderful truck - still have it). As background, there are several videos of this happening on youtube with several discussion groups talking about this problem. The "death wobble" shown in the videos is the same thing I experienced.

While towing my 8000lb trailer, I went over some uneven highway pavement and the entire truck started shaking to the point I was no longer able to control where the truck went I had to left off the gas until it coasted to a top. 50 miles later, I entered a suspension bridge over a 500 foot drop with a tractor trailer coming in the opposite direction. As I crossed over the bridge/road seam the truck started shaking again this time it went in to the lane of the semi truck after leaving a considerable amount of rubber he and I avoided a deadly accident. I googled these symptoms and it appears you have known about this issue for some time, please I beg you for the safety of my family make Ford corporation fix this issue with these trucks.
