Dana 10398904 is a steer knuckle, a genuine Dana part from Pro Gear and Transmission. On a steer axle the knuckle pivots on the kingpin at the axle beam, which lets the front wheel turn while the joint carries the load on the front end.
When that joint wears, the truck can wander, the steering feels loose, the wheel may shake, and the front tires wear unevenly or fast. Call us to confirm proper fit for your application.
