This axle steering knuckle bushing is the original component for the front axle assembly. It serves as the bearing surface between the steering knuckle and the axle housing, allowing the knuckle to pivot smoothly during steering. The bushing is press-fit into the axle eye and provides a controlled clearance for the kingpin or trunnion. Wear in this bushing produces steering play, imprecise directional control, and accelerated wear on the kingpin and seal. As an original part, its bore and outer diameters are machined to the same tolerances as the axle housing bore, so no shimming or reaming is required during installation. On reinstall, ensure the bushing is pressed squarely into the bore and that the lubrication passages align.
