Abstract
A steer axle assembly in accordance with the present invention includes an axle beam defining a first boss with a first bore. The assembly further includes a knuckle body that defines a second boss. The second boss is in the form of a unitary sleeve from which a tie rod arm and steering arm extend. The second boss includes a second bore. The assembly further includes a set of bearings disposed in one of the first and second bores. In one embodiment of the invention, the bearings are disposed in the axle beam bore. In another embodiment of the invention, the bearings are disposed in the bore defined by the knuckle body. The assembly finally includes a kingpin. The kingpin is rotatably received within the bore having the bearings and is rigidly coupled within the bore that does not include the bearings. The kingpin may be tightened to its required specification via the use of a washer and nut on one end of the kingpin.
