See attached description with this report using tcn: Ccn26-19640 description write-up.....updated 04/19/12 the consumer stated the defect involved severe front suspension and steering wheel oscillation that can result in loss of control and lane change at highway speeds. The consumer stated the vehicle performs perfect when not transportation a load at any speed on any road condition. However, when traveling downgrades of 6% or more with the 5th wheel trailer at speeds above 50 mph, a light touch of the brakes to slow the combination vehicle down initiates the oscillation which will not stop the until the vehicle speed falls below 50 mph.

I have a 2006 F250 Super Duty truck that will have violent front end shakes after hitting a pot hole at average road speeds (55-70). It has occurred while towing and during normal driving without towing. When it occurred I had to immediately pull of to the side of the road to regain control of the truck. I believe this to be a very unsafe condition that Ford needs to resolve.

The contact owns a 2006 Ford F-250. The contact was driving approximately 60 mph and drove over a pot hole when the entire vehicle began to vibrate violently and caused the driver to almost lose control of the vehicle. The failure was experienced on an intermittent basis. The vehicle was taken to the dealer where they advised him that they were unable to diagnose the failure. The manufacturer was contacted and they offered no assistance. The failure mileage was approximately 15,000.

Uncontrollable wobble to vehicle after hitting bump on freeway at 65 mph. Not first time and lucky I didn't end up off the freeway. Had service done at Ford dealership for the same problem in Aug 2010, replaced camber casting and two wheel alignment, and tire pressure. Problem is back.

2006 F250 with 36,000 miles. Front end shakes violently after hitting bumps in road. Appears to be more pronounced when encountering a series of bumps and going down hill. There is a loss of effective braking when front end is shaking. Can not understand why no recall when there are so many similar postings submitted. Also front drive universals are being replaced at 45,000 miles and vacuum line for 4 wheel activation has burned off three times, repaired twice my dealer at customers cost.

The contact owns a 2006 Ford F-250. The contact was driving 70 mph and drove over a road bump. The vehicle began to shake violently. The contact received a letter from the manufacturer regarding the "death wobble" that informed owners to change the tires, lower the tire pressure and have a wheel alignment performed. The contact followed the directions according to the letter but to no avail. The contact stated that there were numerous complaints online regarding the "death wobble" and believed that the manufacturer should issue a recall. The failure mileage was 30,000.

I have a 2006 Ford F-250 Super Duty truck. When I hit a rough spot in the road the front end shakes so bad you have no control of the steering. The only way to get it to stop shaking is to get on the brakes and stop. I have been back to the dealer and they tell me there is nothing wrong. Someone is going to get killed if this is not corrected.

Violent shaking of front end after hitting a bump on the road. One strip of highway in our town we can recreate issue everytime.

Over the past 9 months I have noticed a front end/steering wheel vibration at highway speeds in my 2006 Ford F250. At first, the vibration would go away if I accelerated through it or slowed down. It has worsened to the point where it has caused me to partially lose control of the truck. I first bought four new tires. I then had the large retail chain where I purchased the new tires rotate and balance the them multiple times with no improvement. They suggested taking the truck to the dealership to have it checked. I have since had the truck into the dealership multiple times (balancing and rotating, steering dampener, and carrier bearing).

My Ford F250 4X4 truck has a severe shimmy of the front wheels which can occur when driving around 55-60 miles per hour. In order to calm the shimmy or oscillation, I have to slow down at least 10 miles per hour. This has happened on several times, both when towing a 5th wheel and without the 5th wheel. However, it is more prone to occurring when downing the 5th wheel. I took my truck into the Ford dealer to inspect the suspension and adjust the tire pressure, but they said it was all fine. I had an occurrence of this shimmy within 3 days from taking it from the dealer. I have seen there has been some report on this type of behavior, and Ford has stated it is a tire inflation problem, but after taking it into the Ford dealer and them checking it out and then it happening, I think it is something more serious.

Front end death rattle. Going into a curve on a highway and hitting a bump. The front end shakes and rattles to the point where I have to hit the brakes until the speed slows down to about 40 mph. I have changed the steering dampener, the shocks and nothing seems to help. Ford said to check the tire pressure. I've set it to the recommended tire pressure from Ford and I've set it from the tire manufactures recommendations. Nothing works. I've shimmied across several lanes of traffic and am totally surprised that I have not gotten into a accident yet.

I have a problem with my 2006 Ford F-250. My front end wants to veer off the road when I hit pot holes in the road. I have traveled the same roads with my work truck, 2006 F-150 and have little or no problems compared to the F250. I have taken my truck to the dealer I purchased the truck from and have no success getting the problem resolved.

Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6) within the last year and a half I purchased a 2006 Ford F-250, diesel, 4 wheel drive truck. On 3 different occasions, while driving at interstate speeds and immediately after hitting a pot hole or bump, my truck went into a violent front end wobble/cavitation causing a sudden reduction of speed to zero from approx 70 mph. All three times it felt as if the truck was coming apart and had to Dodge traffic and get to the shoulder to inspect the truck. After finding nothing wrong I contacted our local dealership to look at the truck and they tried different air press changes in the tires, and re-alignment, nothing has helped and they refuse to look any further. I started researching this on the internet and found hundreds if not thousands of Ford F-250 truck owners who are experiencing the same problem. You can google "Ford 250 death wobble" or "Ford F250 violent shaking" and read for your self the stories of near accidents and problems Ford refuses to recognize in the design of these trucks. Here recently Ford Motor Co. Has came out with a service bulletin were I have to pay to have Ford fix this problem. Why should I have to pay $40,000 for a truck that has a design flaw and pay for the fix, out of my own pocket as well. A recall needs to be done on these trucks before people get killed, why should someone have to die first before Ford will do anything. Any help you can generate on this would be awesome."this is not a tire press problem, but rather a design flaw." Your report sounds like you side with money instead of consumer safety. [xxx]

2006 F250 front end shakes violently I had near miss on a head on collision.

- Robstown, TX, USA

The failure occurs when your 2006 Ford F250 Super Duty is moving 45-65 mph and you hit a bump, the truck steering becomes oscillating and you can easily loose control if you don't slow down immediately. It feels like the tire is coming loose. We have talked to our local mechanic and he currently has two other trucks with the same problems and is not sure how to fix it.

I own a 2006 Ford F250 Super Duty. It has just passed 16,000 miles on it. When I drive on a highway and hit a bump or pothole the front end of the vehicle begins to shake violently. It radiates through the whole vehicle and it becomes very hard to control and your only option is to slow down and wait for it to pass. I will no longer allow my children to ride in my truck as I feel it is very unsafe. This has happened on several occasions and appears to be getting worse. Ford sent out a bulletin to owners of these vehicles that we must change our tire pressure to 65 psi, but this still does not resolve the problem.

My 2006 Ford F250 4WD superduty pickup shakes violently whenever I hit the smallest pothole or drive over railroad tracks. It is a danger to myself, my children and anyone driving around me on the road. Took the truck to my dealer and almost got thrown out after getting into an argument with both the mechanic and svc manager who said there was nothing wrong with the truck, they never heard of this problem and I need to buy new tires. Tires are brand new with less than 20K on them.

I drive a 2006 F250 and it has been experiencing violet front end vibrations. This occurs at various speeds and I have to slow down or stop to get it to return to normal. It almost caused an accident the other day when I had to slow down to 10 miles per hour on the freeway to get it to stop. Ford claims it is tire pressure but had tires rotated and balanced two days prior. This appears to be a major design issue and a very dangerous one.

- North Richland Hills, TX, USA

The contact owns a 2006 Ford F-250. While driving 65 mph, the vehicle would shimmy when it drove over a bump in the road. The dealer could not provide a remedy; therefore, the vehicle could not be repaired. The contact feels that a crash could occur one day. The current mileage was 74,000 and failure mileage was 32,000.
