NHTSA Defect Investigation #PE07057 ODI has received 78 consumer complaints of severe suspension and steering wheel shimmy and oscillations commencing after the subject vehicles traveled over an uneven road surface. The majority of these incidents occurred at speeds of 50 mph or greater.thirteen of the complaints received by ODI allege loss of steering control and that the vehicle changed driving lanes uncontrollably.four of the complaints received by ODI allege that the vehicle left the road surface as a result of the violent suspension and steering wheel oscillations.in one case the consumer alleges that after the vehicle left the road surface, it crashed into a wooded area.additionalfactors contributing to the opening of this ea were early warning field reports,submitted by Ford, describing suspension shimmy / oscillationsand a Ford tsb (07-10-10) describing the suspension shimmy issue and how to repair the problem.Ford has described shimmy as "self-excited oscillation of the steering wheels with accompanying wheel tramp".this PE has been upgraded to an engineering analysis (ea) to determine if the shimmy condition that occurs on the subject vehicles creates a condition where the vehicle becomes difficult to control or startles the driver, thus presenting a safety risk.

2007 FORD F-350 -- ODI has received 61 consumer complaints of severe suspension and steering wheel oscillations after the subject vehicles traveled over an uneven surface. The majority of these incidents occurred at speeds of 50 mph or higher. Many of the complainants indicated loss of steering control and that the oscillations do not stop until the vehicle has slowed significantly or stopped. Some complainants indicated that the vehicle shifted lanes and spun out as a result of the violent suspension and steering wheel oscillations.
Additional factors contributing to the opening of this PE were early warning field reports, submitted by Ford, describing suspension oscillations and a tsb (07-10-10) submitted by Ford describing the suspension oscillation issue and how to repair the problem.
A preliminary evaluation has been opened to assess the scope, frequency, and safety consequences of the alleged defect.
