Clutch Release Bearing for Hyundai Coupe, Elantra, Matrix and Kia Cerato

The Clutch Release Bearing for HYUNDAI Coupe, Elantra, Matrix & KIA Cerato is a self-centering TKA-type bearing for Hyundai-Kia manual transmission platforms. It directly replaces OEM numbers 4142128001, 4142128002, 4142128010 and 4142128030, so it drops in where the factory Mobis bearing sits.

It is a passive mechanical part and works with CAN-bus 3.0 diagnostics, including CAN FD at 5 Mbps per ISO 11898-1:2015, plus Hyundai-Kia TCU monitoring logic on 7-speed DCT and 5/6-speed manual platforms. Nothing needs coding after install. Market context: global demand for clutch release bearings is projected at $843 million by end-of-2025, and Euro 7 / CARB 2026 rules favor low-friction designs that support CO₂ compliance targets.

Which vehicles it fits

• Hyundai Coupe (GK), 2001–2009, including the Tiburon range
• Hyundai Elantra III / XD (Lantra), 2000–2006
• Hyundai Matrix (FC), 2001–2010
• Kia Cerato (LD), 2004–2009, including the Cerato Saloon

Fitment is confirmed for the Cerato LD with the 1.6L G4ED petrol engine and the 5-speed M5CF1 manual. OEM numbers 4142128001 and 4142128002 are listed in the Hyundai-Kia Mobis EPC for this platform. If your car sits between model years, send the VIN through the Koeep RFQ page and the parts team will verify the correct sub-variant.

Technical Specifications

Material Science: What Is Inside the Bearing

Race and sleeve

The inner race is forged from SAE J403 Grade 52100 high-carbon chromium steel (1.0% C, 1.5% Cr), vacuum-degassed to limit oxide inclusions and induction-hardened to HRC 60–64.

That grade resists the cyclic brinelling and false-brinelling (fretting corrosion) that kills cheaper bearings in stop-start traffic. The CNC-machined steel sleeve carrier follows the approach NSK and PDM validated in their TSK-series retrofit kits.

Cage and grease

The cage is injection-molded PA66-GF25 polyamide rated for 180°C continuous service with peak survivability at 230°C. Clutch housings can soak past 200°C after aggressive driving, so that headroom counts.

The grease is a polyurea-thickened synthetic ISO VG 220 base oil with MoS₂ solid lubricant additives, providing boundary-layer protection during cold-start clutch engagement before the full elastohydrodynamic film forms.

DTC Mapping: How a Worn Bearing Shows Up in OBD-II

A failing release bearing is a mechanical fault, but the TCU sees the consequences. Bearing drag alters clutch fork travel, and out-of-range data sets trouble codes. Expect one or more of these on Hyundai-Kia platforms:

• P0805-P0808: Clutch Position Sensor Circuit Range/Performance, triggered when bearing drag alters clutch fork travel geometry
• P2906: Clutch Actuator Temperature Too High, a Hyundai 7-speed DCT code that can be secondary to release bearing friction overheating
• P0700: Transmission Control System Malfunction, the gateway code when the TCU detects clutch disengagement anomalies
• P0900-P090B: Clutch Actuator Circuit / Stuck, linked to a failed bearing that prevents full diaphragm spring return

These codes sit in the SAE J2012 ranges P0800-P0899 and P0900-P0999. Scan for pending P0800-series codes before you blame the bearing for a noise. If you pull P0806, check for radial or axial play over 0.5 mm; play beyond that pushes the clutch position sensor voltage outside the ECU's learned range.

Side-by-Side Comparison with OEM and EXEDY

On price, this bearing typically runs 30–50% below Hyundai-Kia Mobis counter parts, with production under ISO/TS 16949 quality management and bore ID tolerance at ±0.01 mm. The synthetic grease also holds stability above 200°C, where the OEM mineral pack tops out. The EXEDY BRG947 covers fewer platforms, dropping Tiburon and Lantra from its fitment list.

Service Life and Maintenance Timing

Under normal conditions, expect 120,000–150,000 km of service, in line with Hyundai's published maintenance schedules for manual-transmission vehicles through the 2026–2030 window. Severe-duty use (frequent stop-and-go, mountainous terrain, taxi or rideshare work) calls for an inspection at 90,000 km.

An estimated 4.2 million Coupe (GK), Elantra XD, Matrix (FC) and Cerato (LD) vehicles remain in operation, keeping this SKU in the active 2026–2030 aftermarket cycle.

Replace the release bearing every time you service the clutch. Access requires transmission removal, the same 4–6 hours of labor as a full clutch job, and a bearing that fails 20,000 km after a new clutch means paying that labor bill twice. Hyundai, Kia, Ford, GM, Toyota and Volkswagen mandate release bearing replacement during clutch servicing.

Rear hub bearings

If the car also hums or drones at highway speed, check the rear hubs. Koeep carries a 2-piece rear wheel hub bearing assembly for the Hyundai Accent and Kia Rio, 2018–2021, 1.6L L4 for compact platforms of that era.

Larger sedans and crossovers take a different hub: this single rear FWD wheel hub bearing fits the Hyundai Sonata, Tucson, Kia Optima and Sportage.
