Supplier records
Ask for the OE cross reference, vehicle and axle, hub flange pilot diameter in mm, stud pattern and drawing revision. Treat a conflicting reference as unresolved until fitment evidence is available.
Sourcing Lab / Fitment intake
WJB Bearings Sourcing Lab
Turn a front wheel hub assembly diagram or OE cross reference into a reviewable RFQ. Mark missing flange, ABS encoder and kit information before comparing offers.
Evidence fields for a wheel hub RFQ
Use separate rows for the exact SKU and any proposed replacement. Carry each exception into the supplier comparison.
Sample check
Identify the sample lot and drawing. Have the inspector record the flange datum, measurement setup, observed runout and deviation. Compare the observed value with the buyer-approved limit.
Document scope
Check the issuer, entity, site and expiry on supplier quality-system evidence. Ask the lab or supplier which SKU, revision and conditions the test file actually covers.
ABS interface
Record the ABS encoder ring type, pole count where specified, target face and wheel speed sensor connector keying. A similar flange drawing leaves electrical compatibility unresolved.
Bearing architecture
An integrated unit reduces field assembly work. A serviceable design can retain a separate replacement path where allowed. Verify bore, OD, width, seal lip direction and bearing preload method.
Commercial comparison
Stock offers depend on confirmed SKU and quantity. Custom programs add sample approval and revised minimums. Compare scope, MOQ, Incoterm, lead time and packing per quote.
Carry fitment through to the shipment record
Clarify
Capture axle, drivetrain and drawing revision. Record whether the wheel hub bearing and steering knuckle assembly is requested as a set.
Compare
A single supplier simplifies revision control. With multiple suppliers, normalize carton counts, scope and reporting for each line.
Verify
Agree which fixture, tolerance and method the appointed inspector will use. Keep actual readings against the sample ID for buyer review.
Coordinate
Link the approved part number and lot to carton labels and packing quantities before the forwarder takes over.
