Tie Rods Ball Joints
 

F-350 King Ranch 2005 diesel/dually with 40k miles. Has been serviced every 5k miles. Tows 4-horse living quarters trailer 30% - 35% of the miles. Drives fine but one of the front tires had a bit of wear on the outside so I asked for a front end check...have been told it needs ball joints and tie rods.
Anyone else experience this? Seems odd for such low mileage.
