We have been maintaining our vehicle and had no warning lights at the time our truck died . At the time of the incident it had oil and water. We were driving on the florida turnpike at full speed when suddenly, the truck started shuddering, and then it completely lost power. A cloud of blue-white smoke came out of the back of our truck. We were lucky to be able to get off of the turnpike to a safe place. We could have been killed. The mechanic has determined that the engine is locked up and can't be fixed. Our truck only has 134,000 miles - it should not have blown up like this.

Driving at highway speed (55-75 MPH) the front wheels will start to shimmy and shudder causing steering wheel and front tires to oscillate severely (death wobble) when driving over rough surfaces. This causes entire vehicle to shake uncontrollably. This has caused loss of steering control and can only be be stopped by stopping or slowing vehicle. (unsafe at highway speeds with traffic following)

On I-81 thru harrisonburg, va crossing a bridge with several bumps in it. The steering went into uncontrolled vibration like it was coming apart. I had to slow down to 20 MPH to get it to stop. 20 MPH at night on an interstate is hardly safe. Another time it occurred while entering an on-ramp to an interstate. Again, I had to slow down to 20 MPH to get it to stop. The guy behind me, also trying to merge, almost hit me. The vibrations have occurred since the truck was almost new. The ford dealer says this is normal. I think it represents an accident waiting to happen. It only occurs under specific conditions at speeds of 50-60 MPH, a slight turn and road bumps of a certain frequency to initiate the shaking. Under those conditions, a mechanical resonance with positive feedback seems to create the uncontrollable shudder.
