2011 Ford F350 4X4 48,000 the first time I was driving at 50mph, while driving over a bridge the wheel hit a small hole in the road and put my truck in to a horrible violent wobble! I had to switch lanes and brake to gain control of my truck. I thought it was the hole, but since then at while im traveling at 50+ and pass over any decent size imperfection in the roadway it puts the truck into that dangerous wobble. This needs to be addressed by Ford I do not feel safe driving this truck on the freeway!!! and 80% of my driving for business is on the freeway. Please help Ford owners this is dangerous and cause a horrible accident [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I have owned this truck for 45 days / 2,000 miles. Numerous times I have experienced a suspension malfunction commonly known as a "deathwobble". as of late, it has become increasingly worse. Yesterday's incident required me to lower my speed to 10 mph on a major highway to regain control of my F350 Super Duty. I was nearly rearended by multiple vehicles including a tractor trailer. In addition I nearly collided with a jersey wall on a bridge. Taking the vehicle back to the dealer, but want to ensure that there is a record of the danger in this vehicle.

Steering goes into violent shaking. Feels like tires are falling off. Slowed down and stopped. According to you're reports this is not the first time for this problem. This should be a recall before someone gets killed because of this.

I have a 2011 Ford sd F-350 srw with 26505 miles. On several occasions, I have experience violent front end shimmy after hitting a bump in the road or an expansion joint on a bridge or on the freeway. The vehicle requires sudden braking to bring the vehicle back in control. The front end shakes violently to the point of taking the steering out of your hands. This is very dangerous. The last time it occurred I was on a bridge. The violent movement of the front end moved me into the adjacent lane, luckily, there was no vehicle in the lane. I could have caused an accident due to this problem.

While driving in the left side passing lane and coming up to a slight left bend in the road the truck went over a expansion joint in the road, if there is slight pressure on the steering wheel from holding the truck into the left bend in the road the trucks wheels will start to shake and wobble, it will get so bad you need to hold the steering wheel with two hands and guide the truck to a complete stop in that left lane so to make it go away. This is real scary. I know there is items on the web sights that will fix this problem, but Ford will void your warranty if they find any aftermarket parts on the truck. What I don't understand is Ford knows there is a problem with this wobble and if you go and fix it they void your warranty.

Front wheels went into an extreme wobble after hitting a bump, and would not stop wobbling until I came to a complete stop.

The contact owns a 2011 Ford F-350 sd. While driving 60 mph, the contact drove over a bump and the vehicle started to shake excessively, causing him to lose control of the vehicle. The dealer informed the contact that the steering dampner was faulty and needed to be replaced. The manufacturer had not been notified and the vehicle was not repaired. The approximate failure mileage was 36,000 and the current mileage was 38,000.. updated 12/07/11 updated 12/12/11
