Parts for your 2010 Mitsubishi Lancer-Thrust bearing

2010 Mitsubishi Lancer thrust-bearing — what it is, where it fits, and when to sort it

Technical references including the Mitsubishi Lancer CJ Service Manual (Clutch section), the Mitsubishi 4B11/4B12 Engine Workshop Manual (main bearing/thrust clearance), and Jatco JF011E (RE0F10A) CVT service literature confirm that thrust-bearings are relevant to the 2010 Lancer. Manual-transmission models use a clutch release (thrust/throwout) bearing, all 4B1 engines use crankshaft thrust bearings integrated with the main bearings, CVT and conventional automatics do not have a serviceable clutch thrust bearing.

On manual 2010 Mitsubishi Lancer models, the thrust-bearing (commonly called the clutch release or throwout bearing) sits between the clutch fork and the pressure plate’s release fingers. Its job is to let the clutch assembly and the gearbox input shaft spin while the pedal force is applied smoothly, reducing friction and heat at that contact point. That keeps pedal effort consistent and helps the clutch disengage cleanly during shifts. It’s a small part, but it has a big say in shift feel and driveline refinement.

The 4B11/4B12 engines also run thrust faces on the crankshaft main bearings to control end float. Those engine thrust bearings aren’t a routine service item, they’re inspected and renewed during engine rebuilds or when end float is out of spec. For typical servicing, the manual-trans clutch thrust-bearing is the focus.

Best practice on a Lancer manual is to replace the thrust-bearing whenever the clutch is out for a disc and pressure plate. The bearing lives the same hard life as the clutch and the extra parts cost is minor compared with the labour to pull the gearbox again. Drivers who habitually ride the clutch pedal, sit at lights with the pedal depressed, or drive frequently in stop–start conditions will load the bearing more and may see earlier wear.

• Typical symptoms of a worn clutch thrust-bearing:
  • Whirring, chirping, or grinding noise with the clutch pedal pressed that quietens when released
  • Notchy or reluctant gear engagement when stationary
  • Vibration felt through the pedal during take-up

Service tips for the 2010 Lancer:

• Replace the release (thrust) bearing with any new clutch kit
• Inspect the clutch fork pivot and guide tube, lubricate per service manual
• Check pedal free play and hydraulic operation to avoid partial engagement that cooks the bearing
• CVT/auto owners: there’s no clutch thrust-bearing to service, noises under load are likely elsewhere

Quality OE-equivalent bearings, correct installation, and good driving habits will see the Lancer’s thrust-bearing run quietly for many kilometres.

Popular questions

Does a 2010 Mitsubishi Lancer have a thrust-bearing?
Yes. Manual-transmission models use a clutch release (thrust/throwout) bearing. The 4B11/4B12 engines also incorporate crankshaft thrust bearings within the main bearing set. CVT and automatic models don’t have a serviceable clutch thrust-bearing.

What are the signs the clutch thrust-bearing is failing?
Most owners notice a whirring, chirping, or grinding noise when the clutch pedal is pressed that fades when the pedal is released. There can also be a rough pedal feel or a slight shudder on take-up. If ignored, the bearing can seize and damage the pressure plate fingers.

Should the thrust-bearing be replaced with the clutch?
Absolutely. The labour to access it is the same as a clutch job, and bearings wear at a similar rate to the disc and pressure plate. Swapping it as part of a complete clutch kit is the most cost-effective approach.
