The Ford Super Duty has a generally well-deserved reputation for toughness and the ability to handle heavy loads. But it appears there could be a potential weak spot on some 2008 F-250 and F-350 models. The National Highway Traffic Safety administration has received five reports of steering loss on the models, with two causing the vehicles to go off the road and one resulting in a car-to-car collision.

A total of 340,000 trucks may potentially be subject to the investigation. Two complaints allege the steering wheel spun freely with no apparent directional control. A failure of the steering gear box would seize the steering shaft, causing a shearing of the steering wheel shaft pin. One of the failures caused the truck to veer off the road at 35 mph, and another ran into a parked car at 20 mph. The failures all occurred on vehicles with less than 100,000 miles. One complaint claims two steering box failures within 4000 miles of each other.

None of the cases reported so far have resulted in serious injury. If you have experienced a similar issue, and want to report it to the agency, go to www.odi.nhtsa.dot.gov/ivoq.
