Ford Bronco Dana 30 Front Axle Steering Knuckle & Roller Bearings Cutaway

This document is a cutaway cross-section schematic illustration of a front axle steering knuckle assembly, uploaded to a 1974 Ford Bronco gallery and identified by the uploader as depicting a Dana 30 axle knuckle. The illustration shows the axle housing, axle shaft with universal joint, wheel hub, and the steering knuckle pivot arrangement. Two callout labels are present: 'ROLLER BEARINGS,' with leader lines pointing to the upper and lower kingpin-style bearing assemblies (highlighted in orange) on which the steering knuckle pivots, and 'STEERING KNUCKLE,' pointing to the knuckle casting that wraps around the axle universal joint. The image carries a 'Copyright FoMoCo' (Ford Motor Company) mark, indicating it originates from Ford factory literature. A reader can learn from this diagram how the steering knuckle pivots on upper and lower tapered roller bearings, how the axle shaft's U-joint sits inside the knuckle at the pivot centerline, and the general internal arrangement of a closed-knuckle-style front drive axle. The document contains no part numbers, torque specifications, or year/model applicability text — it is purely a labeled sectional view for identification and understanding of component relationships.
