Front Suspension Stabilizer Bar problems of the 2008 Dodge Ram 3500

Death wobble! I hit a pot hole or rough bump in the road and the suspension shakes so violently that I could hardly hold on to the steering wheel. All the items on the console went on to the floor, cleared the dash and center console. This was the first of 5 times I have had this happen. 3 times when coming off a bridge deck. All times the truck is at approximately 65mph. The only way to stop the violent shaking is to brake and bring the vehicle to a near stop. The problem with this is its always happened on the freeway where there are other vehicles all around. Very dangerous and scares the life out of me. I have replaced steering control link with tie rod ends. Stabilizer bar, added after market steering box stabilizer and done two alignments. All parts are like new there is only 55000 miles on the truck. There is definitely a design flaw with the suspension! I have owned 4 other trucks. 2 with solid axles in the front and never had this problem.
