| Vehicle identity | Model year, make, model, trim, engine, and VIN | Use the VIN from the vehicle registration or windshield and check it against a current application catalog. | All vehicle details must match the catalog listing for 515036. |
| Axle position | Front or rear; left or right where the application specifies a side | Check the catalog application notes and compare them with the vehicle’s repair information. | The assembly must be listed for the required axle position and side. |
| Drivetrain and axle configuration | Two-wheel drive or four-wheel drive; applicable axle and suspension configuration | Confirm the drivetrain from the VIN or vehicle build information, then check the catalog’s exclusions and notes. | Do not assume a part listed for one drivetrain fits another. |
| ABS compatibility | Anti-lock braking system (ABS) sensor, encoder, and electrical connector configuration | Compare the vehicle’s original assembly and connector with the catalog description and installation information. | Sensor and connector type must match; do not rely on visual similarity alone. |
| Mounting interface | Flange shape, mounting-hole arrangement, pilot diameter, and mounting depth | Compare manufacturer specifications or measurements from the original assembly with the replacement listing. | Mounting points and locating surfaces must match the vehicle specification. |
| Wheel and axle interface | Wheel-stud count and spacing, hub pilot, and axle-shaft or spline interface where applicable | Check catalog specifications and service information; compare with the original part if it is still available. | Every interface must match; do not infer dimensions from the part number. |
| Brake and wheel clearance | Compatibility with the vehicle’s brake rotor, caliper, and wheel assembly | Confirm the catalog application and compare the specified hub offset and assembly dimensions. | The assembly must preserve the vehicle’s specified brake and wheel fit. |
| Original part comparison | Markings, connector, mounting face, and major dimensions of the removed assembly | Record the original part identification and compare it with the replacement documentation. | A visual match is useful but does not replace VIN-based catalog verification. |
| Final pre-installation check | Part number, package condition, supplied hardware, and installation instructions | Confirm the label identifies 515036 and review the applicable vehicle service procedure. | Stop installation if the part, connector, or fitment details do not agree. |
