Parts for your 2019 Mitsubishi Asx-Thrust bearing

2019 Mitsubishi ASX thrust bearing — what it is and when it matters

Based on Mitsubishi factory service information and parts catalogues for the GA‑series ASX/Outlander Sport (2019 MY), the 2.0‑litre petrol engine uses an integral crankshaft thrust bearing, and 5‑speed manual models also use a clutch release (thrust) bearing. CVT models do not have a clutch release bearing. These details are shown in Mitsubishi workshop manual sections covering the engine crankshaft (Group 11) and the clutch system (Group 21), as well as OEM parts diagrams.

In the engine, the thrust bearing is part of the main bearing set and controls crankshaft end‑float. It keeps the crank from walking forwards and back under axial loads from the accessory drive and, on manual cars, the clutch. Kept happy by clean engine oil, it’s a fit‑for‑life component that isn’t serviced on its own unless the engine is being rebuilt.

On 2019 ASX models with the 5‑speed manual, there’s also a clutch release (often called “thrust”) bearing. Its job is simple: when the driver presses the pedal, the bearing rides the pressure plate’s fingers and allows smooth, quiet disengagement of the clutch. It’s a wear item and the smart play is to replace it whenever the clutch is done.

Practical servicing advice for an ASX manual owner:

• Replace the release bearing with the clutch kit to save on labour and avoid repeat gearbox removal.
• Listen for a light whirr, chirp, or squeal that appears with the clutch pedal depressed and fades when released — classic release‑bearing noise.
• Have the clutch fork, pivot, guide tube and input shaft splines checked and lubricated per spec, rough or dry hardware shortens bearing life.
• Avoid riding the clutch — it loads the bearing and can add axial load to the crank.

For CVT‑equipped ASX models, there’s no clutch release bearing to maintain. The engine’s thrust bearing is not a routine service item, the best protection is regular oil and filter changes with the correct spec oil at the intervals in the service book. Any sign of abnormal crank end‑float (e.g., pulley movement or changes in clutch engagement on manuals) warrants professional diagnosis, but that’s uncommon on a well‑serviced ASX.

• Does a 2019 Mitsubishi ASX have a thrust bearing?
  Yes. All engines in the 2019 ASX have a crankshaft thrust bearing. Manual‑transmission models also have a clutch release (thrust) bearing, CVT models do not use a release bearing.
• What are the signs of a failing clutch thrust/release bearing on an ASX?
  Typical symptoms are a whirring, chirping or grinding noise when the clutch pedal is pressed, rough or notchy pedal feel, and possible vibration through the pedal. If the noise disappears when the pedal is released, the release bearing is the prime suspect.
• Should the thrust/release bearing be replaced with every clutch?
  It’s best practice to replace the release bearing whenever the clutch is replaced. The gearbox is already out, the bearing is relatively inexpensive, and doing it together prevents repeat labour. It’s also a good time to inspect the fork, pivot, guide tube and rear main seal, and to resurface the flywheel if needed.
