FORD recall on F450 CHASSIS CAB and F550 CHASSIS CAB models

On certain vehicles, the steering gear may contain a gear piston that was assembled with an incorrect re-circulating ball tube retainer. An incorrect retainer may result in an improperly retained re-circulating ball tube, which may not keep the re-circulating balls in place during steering gear actuation. If the re-circulating balls become dislodged, a vehicle operator may notice noise and increased steering efforts that may eventually progress to impaired steering or potential loss of steering control. Correction: Dealers will inspect and, if necessary, replace the steering gear.
