Assign the sample a stable ID, preserve its supplier model and RFQ line, verify the OE/application evidence, photograph every critical interface, compare drawing-defined characteristics with a controlled method, record ABS or encoder configuration and supplied hardware, review packaging, and resolve every deviation before release. Approve a named revision for a named customer scope—not a generic ‘looks good’ sample. Bulk supply must match the approved evidence, and any later change should trigger documented review.

Use twelve controlled checks: source OE number, vehicle and market, model-year or chassis boundary, axle, side, driven status, hub construction, flange and mounting pattern, bore or spline, studs and threads, ABS or encoder configuration, and kit contents. Record the source and status of every field. A candidate cross-reference is not confirmed fitment, a matching connector is not proof of signal compatibility, and a similar photograph is not interchange evidence. Final approval should link the exact quoted item to the evidence reviewed.

Use a wheel hub OE number as a traceable starting reference, then verify it against the vehicle and the physical hub configuration before ordering. Record the number exactly as shown on the OE catalog, label or sample, including prefixes, suffixes, spaces and hyphens. In separate fields, add the source, vehicle make and model, model year or chassis range, front or rear axle, left or right side, drive configuration, ABS encoder or sensor details, flange and bolt data, spline count, key dimensions and quantity. Keep OE numbers, aftermarket cross references and supplier model numbers in different columns so they are not mistaken for the same identifier type. If a number has been superseded or appears against several vehicle variants, mark the row for confirmation rather than assuming interchange. A supplier-ready RFQ is one application per row with evidence attached.

Identify an ABS-equipped wheel hub assembly by combining the OE reference and vehicle application with physical evidence of the sensing system. Check whether the unit has a magnetic encoder integrated into a seal, a visible tone ring, an internally mounted sensor, or an external sensor lead and connector. Record the encoder or sensor side, cable routing, connector shape and pin arrangement, plus the axle position, drive configuration, flange, spline and mounting dimensions. A dark seal surface can contain a multipole magnetic encoder even when no teeth are visible, so appearance alone is not enough. Because sensor and target arrangements vary by vehicle, the safest RFQ includes photos of both faces, the connector and label, together with the OE number, vehicle model year and quantity. The supplier should confirm the complete configuration before interchange approval.

A wheel bearing is the rolling-element component that supports rotation at the wheel end. A wheel hub assembly is a more integrated replacement unit that can combine the bearing with one or more mounting flanges, wheel studs, a splined bore, seals and an ABS encoder or sensor connection. The terms overlap because later-generation hub bearings integrate functions that were separate in earlier designs, and aftermarket catalogs do not always use the same naming convention. Buyers should therefore specify the OE reference, vehicle and model year, front or rear axle, left or right side when applicable, driven or non-driven position, ABS configuration, flange and bolt details, spline count, key dimensions and required quantity. Those identifiers are more reliable than requesting a part from the words “wheel bearing” or “hub assembly” alone.
