One problem related to steering gear box has been reported for the 2005 Ford F-350. The most recently reported issues are listed below.
Making a left hand turn the steering failed causing the truck to run into a pole. The truck is being repaired using a much stronger steering box by my Ford dealer. This is being paid for by my insurance CO. Even thow the truck has only 26000 miles on it and is under factory warrenty. I will get the undersize broken steering box. The truck has the original suspension,wheels,and tires it came with. Thanks Ford.
