Parts for your 2012 Mitsubishi Lancer-Thrust bearing

2012 Mitsubishi Lancer thrust-bearing — what it does and when to sort it

Based on technical references — the Mitsubishi Motors Lancer CJ/CF Service Manual (2012, Clutch and Manual Transaxle sections), the Mitsubishi ASA electronic parts catalogue for CJ/CF models, and Jatco CVT service information — a thrust-bearing (commonly called the clutch release bearing) is fitted to 2012 Lancer models with a manual gearbox. It’s not used on CVT-equipped Lancers, and the Ralliart’s Twin‑Clutch SST houses its own internal release hardware that isn’t serviced as a standalone “thrust-bearing”.

On a manual 2012 Lancer, the thrust-bearing sits on the gearbox input shaft collar and presses on the clutch diaphragm spring when the pedal’s pushed. Its job is to convert that pedal movement into smooth, axial force so the clutch can disengage cleanly. When it’s healthy, gear changes feel light and tidy, when it’s tired, drivers may hear a chirp, squeal, or rumble that changes as the pedal is pressed, or feel a slightly gritty pedal and notchy shifts.

This bearing isn’t on a time-based service schedule, but it’s smart to replace it any time the clutch is out — typically somewhere around 120–200,000 km, depending on driving style. The Service Manual guidance is straightforward: if the bearing feels rough, drags, or is noisy when spun by hand, replace it. Most workshops will fit a complete clutch kit (pressure plate, friction disc, release bearing) because mixing old and new bits can shorten the life of the lot.

• Best practice during a clutch job:
  1. Inspect and lightly lube the release fork pivot and bearing carrier with high-temp moly grease, don’t grease the bearing contact face.
  2. Check for oil leaks from the gearbox input seal or engine rear main — oil contamination will kill a new bearing fast.
  3. Use quality OEM-spec bearings (common suppliers include NTN/NSK) and renew clips/springs if specified.
  4. Bleed the hydraulic system and verify pedal free play per the Service Manual.

Good habits help: avoid resting a foot on the clutch, and at long lights pop it in neutral rather than holding the pedal down. For CVT models, a traditional thrust-bearing isn’t part of the driveline, so any noise under load or at idle points to different components entirely.

Popular questions

Does every 2012 Lancer have a thrust-bearing?
No. Manual-transmission cars do. CVT models don’t use a clutch release (thrust) bearing, and the Ralliart’s Twin‑Clutch SST has internal release hardware that isn’t serviced as a separate thrust-bearing.

What are the tell-tale signs the thrust-bearing is on the way out?
A chirp, squeal, or rumble that changes when the clutch pedal is pressed, a rough pedal feel, or trouble selecting gears. If the noise disappears when the pedal’s released or vice versa, that’s a classic clue. A proper inspection with the gearbox out confirms it.

Should the bearing be replaced on its own or with the clutch?
It can be done on its own, but it’s usually better value to replace it with the full clutch kit while the gearbox is out, especially if the disc or pressure plate shows wear. That way the whole system starts fresh.
