Steering Linkages problems of the 2005 Ford F-350

I have a 2005 Ford f350 superduty and on several occasions I have been driving down the road and have gone over blemishes in the highway and it has caused a violent shaking in the front end. It has gotten so bad at points that it almost caused a severe accident which might have involved many. This has happened on many occasions and I have to slow down and stop before it subsides. I have been to several dealers and they all say that they have a quick fix but nothing seems to work. Everytime I have tried to fix the problem I have paid for it out of my own pocket. I have spoekn with many for superduty owners that have had this problem and they all say the same thing. This is not only a problem for the driver of the vehicle but also for others on the road as well. Do people need to start dying before there is a service recall to fix the problem. Ford didn't start replacing tires on trucks and SUV's before so many people died in care crashes. This is a severe problem and needs to be addressed. There should be no call for paying for and being financially locked into a $50,000 vehicle that could be considered a death trap. This problem exists in all models of the Ford superduty and Ford still produces these and sells them to consumers and doesn't fix them.

We own a Ford f350, 2005 model with about 6000 miles. On sun. ,3/4, as my wife drove away from a service station pump, she lost control of the truck, I. E. She could not steer. Lucky for her she was able to stop before entering a heavily traveled highway. We found that the nut holding the pivot arm with the steering linkage had sheared off along with the cotter pin holding the nut. The nut threads were stripped off. I have the failed nut along with ring/clip holding the cotter pin. The bolt threads on the linkage, to the eye appear to be o'k. As stated though, the nut threads were stripped off. Was this due to a softer metal being used, over torquing or a bad nut??' the truck was towed to newberg Ford in newberg, or.
