What Each Diagram Tells You
Use the diagrams to identify the hub family first, then confirm the exact replacement assembly by part number, application, and sensor or axle details.
Non-driven hub: free-rolling support layout
The non-driven diagram is the right reference when the wheel end is carrying load and rotating freely without transmitting engine or axle torque through the center of the hub. This layout is common where the wheel assembly behaves as a support point rather than a powered drive connection.
Driven hub: support plus power transfer
The driven diagram is the right reference when the hub assembly also interfaces with a driven axle or shaft. Because the assembly has to handle torque transfer as well as wheel support, the design can include spline engagement, different sealing needs, and added service considerations.
Why the comparison matters before ordering
Misidentifying a driven hub as non-driven, or the reverse, can send a buyer into the wrong part family immediately. The diagrams help you avoid that first mistake, especially when the application details are incomplete or the old bearing or hub has already been removed.
What to confirm after using the diagrams
Once the diagram gets you into the right hub category, verify the exact replacement using the OE or interchange number, axle and sensor details, flange pattern, and any application-specific notes. The diagram narrows the search; the part number finishes it.
