While traveling West bound on interstate 70 in a construction zone with uneven pavement the vehicle's right front wheel passed over a pavement patch which was slightly raised. Almost immediately the left front wheel passed over a pavement patch which was slightly raised. These two relatively minor bumps caused a wobble in the steering which then intensified until the vehicle steering was virtually uncontrollable. In order to stop the violent bouncing and wobble I had to brake hard almost coming to a stop. This unexpected rapid speed reduction quite naturally caused vehicles to have to brake very hard to avoid a collision. Subsequent research on the internet has revealed that this is not an unusual problem with this vehicle. www.thedieselstop.com/forums/F149/front-end-bounce-high-speeds-274673/ it is important to note that I am not a beginner at operating heavy duty pick up trucks. I drove 3/4 ton and one ton 4X4 trucks for 30 years as part of my duties as a rural area law enforcement officer with co-lateral duties in remote area search and rescue. Had I been towing my fifth wheel trailer when this high speed wobble occurred it could very well have resulted in a major traffic incident/collision involving multiple vehicles. As it was we were very lucky to have avoided rear end collisions as a result of the necessity to unexpectedly brake and slow to regain control of our truck.

Driving approximately 45 mph on a state highway, making a slight left turn, hit a small bump in the road, and the steering wheel started jerking violently from left to right from the 9:00 to 3:00 positions. I could not stop it with both hands. I had to brake the vehicle to almost a complete stop to end the jerking. This has been happening on almost a daily basis. The vehicle currently has 22,193 miles on it. It has been to the dealership at least 4 times and they have been called numerous times with the problem. They have checked the tire pressure several times. The front end. Changed the steering damper, which slightly helped for about 500 miles. It is now happening every time I drive the vehicle and is getting worse. Now also happening at lower speeds, around 30 mph and up.
