Hyundai and Kia Wheel Bearing OE Cross-Reference Guide

What This Guide Covers

This guide provides a structured OE-number reference for Hyundai and Kia wheel bearing sourcing. It covers 11 catalogue numbers linked to wheel bearing and front wheel hub bearing product groups, including 40210-ZP50A, 43550-42030, 51720-1G000, 51720-2B000, 51720-2H000, 51720-2S000, 51720-3W000, 51720-A7000, 44300-SNA-A02, 527202P000, and 8L8Z-1104-A. Eight of these numbers have published OE detail pages that can be used during cross-checking.

The information is intended for parts importers, distributors, and purchasing teams that need to compare an OE number with the corresponding catalogue product before requesting a commercial quotation. It also explains the fitment distinctions between the general wheel bearing listing and the two front hub bearing groups associated with the Elantra, Cerato, i30, Tucson, ix35, and Sportage.

Wheel bearing identification should be based on the complete OE number, product configuration, and vehicle application together. An OE number alone should not replace a physical or packaging check because catalogue records group several references within related product families. The correct sequence is to verify the number, confirm the product category, compare the specifications, and then request a quotation with the required SKU quantity clearly sta

How to Identify the Right Part

Begin with the OE number printed on the bearing, hub, package, or parts documentation. Preserve every character, including hyphens, spacing, and letter suffixes. For example, the suffix in 51720-A7000 must not be shortened, while the full form of 51720-2H000 must be matched as written. Searching by only the first six characters can create confusion across multiple catalogue references.

Next, distinguish the general Hyundai and Kia wheel bearing catalogue from the front hub assemblies used in specific vehicle groups. The general product page lists 43550-42030, 44300-SNA-A02, 40210-ZP50A, and 8L8Z-1104-A. Its listed specifications include an IP68 double seal, an integrated ABS tone ring on Gen 3 units, factory-set preload, and an angular contact, tapered, Gen 3 hub design.

For compact models, compare the front wheel hub bearing for Hyundai Elantra and Kia Cerato. The catalogue associates this product with 51720-1G000, 51720-2H000, and 51720-A7000. It is described as a double-row angular contact unit with an integrated magnetic encoder ABS ring, a maintenance-free sealed design, and high-temperature pre-filled grease.

For the SUV group, compare the front wheel hub bearing for Hyundai Tucson and Kia Sportage. The listed references are 51720-2S000, 51720-3W000, and 51720-2B000. The product is described as a double-row angular contact unit with an integrated ABS ring, a maintenance-free seal, and compatibility with both 2WD and AWD applications.

Physical confirmation should include the hub flange, mounting geometry, ABS ring arrangement, seal construction, and overall configuration. These checks help prevent a general wheel bearing from being selected for a hub-bearing application. Any mismatch between the requested OE number, packaging, and fitted configuration should be resolved before shipment

OE Number Cross-Reference

The following cross-reference table groups the catalogue numbers by the product name used in the fitment records. Use the complete OE number as written when preparing an inquiry. Published OE pages can provide an additional reference point for eight entries, while three numbers are included in the catalogue without a published OE detail page.

For a direct catalogue check, review OE 40210-ZP50A wheel bearing details and OE 43550-42030 wheel bearing details. Each published page identifies the corresponding part as a wheel bearing with Hyundai and Kia fitment. The product grouping should then be confirmed against the exact application.

The compact-model hub references also have dedicated records: OE 51720-1G000 hub bearing details, OE 51720-2H000 hub bearing details, and OE 51720-A7000 hub bearing details. These entries share the Hyundai Elantra, Kia Cerato, and i30 fitment description.

For the SUV group, use OE 51720-2B000 hub bearing details, OE 51720-2S000 hub bearing details, and OE 51720-3W000 hub bearing details. The catalogue identifies these with the Hyundai Tucson, ix35, and Kia Sportage group. The remaining references, 44300-SNA-A02, 527202P000, and 8L8Z-1104-A, belong to the general wheel bearing listing and do not have publis

Vehicle Fitment

Vehicle Fitment

The catalogue lists Hyundai and Kia as the overall fitment brands. The more specific front hub records divide the applications into two groups. The Hyundai Elantra, Kia Cerato, and i30 group is associated with 51720-1G000, 51720-2H000, and 51720-A7000. These numbers should be checked together with the compact-model hub product specifications before inclusion in a quotation request.

The Hyundai Tucson, ix35, and Kia Sportage group is associated with 51720-2S000, 51720-3W000, and 51720-2B000. The corresponding product is identified as a front wheel hub bearing for SUV applications and is listed as compatible with 2WD and AWD. Those drive configurations do not remove the need to verify the complete OE number and hub configuration.

The general wheel bearing references are listed for Hyundai and Kia without a more specific model grouping in the supplied catalogue: 40210-ZP50A, 43550-42030, 44300-SNA-A02, 527202P000, and 8L8Z-1104-A. For a distributor order, these references should remain tied to the general wheel bearing product page rather than being moved into the Elantra, Cerato, i30, Tucson, ix35, or Sportage hub groups without additional verification.

Fitment matching should therefore operate at three levels: brand, named model, and complete OE number. A Hyundai designation alone is not enough to establish interchangeability, and two products serving the same brand may belong to different hub configurations. Keep the fitment record, OE number, and product specifications toge

Pricing, MOQ and Lead Time

MOQ is 10 pieces per SKU. Pricing is FOB quotation on request, so the commercial offer should be prepared against a defined SKU and quantity rather than represented by a fixed unit price. Distributors planning mixed model coverage can identify the relevant OE numbers first, group them by product family, and request quotation lines for the quantities required under each SKU.

The quotation lead time is 1 business day. This is the stated lead time for a quotation and should not be interpreted as a stock statement or a shipment commitment. The catalogue does not confirm stock availability, so inventory status should not be inferred from the product listings or OE pages.

For an efficient request, provide the exact OE number, vehicle application, product family, required quantity, and destination if additional quotation information is requested. Examples include 51720-1G000 for the Hyundai Elantra, Kia Cerato, and i30 group or 51720-3W000 for the Hyundai Tucson, ix35, and Kia Sportage group. Keeping the request SKU-specific helps prevent ambiguity when one product page contains several cross-referenced numbers.

General bearing enquiries can use 43550-42030, 40210-ZP50A, 44300-SNA-A02, or 8L8Z-1104-A as the identifying reference. For the two hub-bearing groups, use the OE numbers assigned to the matching vehicle category. The quotation response can then be evaluated against the correct catalogue product rather than against a broa

Common Failure Signs

Common Failure Signs

A worn or damaged wheel bearing may be associated with a hum that changes with vehicle speed, vibration during travel, or a grinding noise from the wheel area. These symptoms justify inspection, but they do not by themselves establish that the failed component is a general wheel bearing or a front hub bearing. The unit type and OE number must still be confirmed.

ABS-related warning indications can prompt a check of the integrated ABS ring, but the catalogue specifications differ between product groups. The general wheel bearing has an integrated ABS tone ring on Gen 3 units, while the compact-model hub bearing uses an integrated magnetic encoder ABS ring and the SUV hub bearing is listed with an integrated ABS ring. This difference matters when diagnosing or quoting a replacement.

Other inspection points include looseness, rough rotation, heat, damaged seals, contamination, corrosion, and play at the hub. A sealed-for-life or maintenance-free seal description does not mean the unit requires no inspection. It describes the listed seal configuration, not a claim that bearing defects cannot occur.

Moisture intrusion, impact damage, or incorrect installation can compromise a bearing even when its exterior appears clean. The best sourcing practice is to remove and inspect the existing unit, retain its identification markings, and compare the replacement configuration with the

Quality Checklist

Quality Checklist

For incoming inspection, confirm that the package identification and physical bearing correspond to the ordered OE number. Check that no component has been dropped, damaged, or contaminated during handling. Protect the sealing surfaces and integrated ABS ring from impact during transport and unpacking.

Verify the product-specific construction against the catalogue. The general wheel bearing is listed as IP68 double-sealed, with factory-set preload and an integrated ABS tone ring on Gen 3 units. The Elantra, Cerato, and i30 front hub bearing is listed as double-row angular contact with an integrated magnetic encoder ABS ring, maintenance-free sealed construction, and high-temperature pre-filled grease.

For the Tucson, ix35, and Sportage front hub bearing, check the double-row angular contact design, integrated ABS ring, maintenance-free seal, and stated 2WD and AWD compatibility. The catalogue also records the OEM reference pair 51720-2S000 / 51720-3W000 for that product.

Finally, record the quantity received against the SKU MOQ of 10 pieces and compare the supplied number with the purchase order. If the received unit differs from the expected configuration, quarantine it for review and retain the packaging and identification details for the discrepancy record. A precise receiving process is especially important where sever
