Download ISSUE Some 2005-2007 F-Super Duty vehicles may exhibit steering wheel oscillation (back and forth motion), immediately following front or rear wheel impacts (i.e. pavement joints, frost heaves, rough roads, etc.). Steering wheel motion is typically in the range of ± 5 degrees, and typically dampens out in fewer than five oscillations. This condition occurs mostly on F-250/F-350 4X4 vehicles, and is more evident on trucks equipped with a gas engine. ACTION Refer to the following Service Procedure to minimize the steering wheel oscillations on impacts, however, there may be some remaining minor oscillation which would be considered normal. SERVICE PROCEDURE SUMMARY 1. Set tire pressure and road test vehicle to evaluate vehicle before proceeding with further repairs. If issue is resolved, do not proceed with the rest of this TSB.
