  • Quantity, target market and destination

Interface and evidence matrix

CheckRecord in the briefReview before acceptance
ApplicationOE cross reference, vehicle and model year, drive layout and axle position. Use a vehicle identifier only when necessary through a channel agreed with the desk.Resolve catalogue supersessions and trim variants against the buyer reference before release.
Hub flangeMounting pattern, pitch circle diameter (PCD), pilot diameter, offset and flange depth. For the mating wheel, include center bore, wheel offset (ET), rim size, load rating and finish.Match the supplier drawing to the assembly revision. For lateral runout, agree the mounting datum, fixture and indicator position on the flange. Rotate the mounted sample one full turn and record maximum minus minimum indication against the drawing limit.
ABS encoderMagnetic or toothed design, reading face, pole or tooth count where specified, connector keying and harness route where fitted.Match the encoder and sensor interface to the vehicle configuration. Compare a sample against the approved drawing or reference part.
Bearing and sealBore, outside diameter, width, seal lip orientation and included installation hardware. State whether the platform uses a serviceable bearing or a hub unit.An integrated hub may reduce field assembly steps. A serviceable bearing retains separate replacement where the vehicle permits it. Use the vehicle service procedure for bearing preload or endplay and verify the kit contents separately.
Tire line, where applicableSize, load index, speed rating, duty cycle, tread pattern, quantity and destination port.Review market-specific requirements against the exact tire model and report scope before purchase. A size such as 225/45R18 does not establish load index or speed rating.

Documents that resolve a fitment question

Supplier-provided

Drawing crosswalk

List buyer and supplier drawing numbers together with the quoted revision.

Supplier-provided

Part record

Tie the report or declaration to the part ID, revision and intended market. An IATF 16949 or ISO 9001 certificate is a management system record. Ask for separate product evidence where the application requires it.

Third party

Measurement sheet

Record the sample ID, datum, method and results for requested dimensions.

Third party

Interface inspection

Check the connector and encoder against the buyer-supplied criteria.

Buyer-approved

Application match

Record who accepts the application, axle and reference number combination.

Buyer-approved

Deviation decision

Keep each open discrepancy beside the approved disposition and revision.
