2006 FORD F250 SD User Comment / Complaint

Took to dealership at approxiamtely 10,000 miles and they performed tsb's (technical service bulletins). have taken vehicle to 2 different dealership dealers now going on the 8th time for same issue. the truck experiences a dangerous "hyper-shake" at approximately 50-70 mph. the truck shakes violently side to side, and up and down and drifts out of lane and to correct it must apply the brakes. steering of the vehicle is significantly impeded , and shaking continues until truck speed is decreased to approx. 30 mph. i have done all suggestions given to me by the dealerships. rebalance tires, checked alignment and tire pressure. i am currently taking this vehicle to ford dealership march 23, 2007 for them to try and fix the hyper-shake. this is very dangerous issue and it needs to be corrected. this vehicle is not highway safe.
