Parts for your 2008 Mitsubishi Lancer-Thrust bearing

2008 Mitsubishi Lancer thrust-bearing: what it is, where it’s used, and when to replace

Based on the Mitsubishi Lancer CJ (2007–2013) Workshop Manual (Group 22A: Clutch and Group 11A: Engine Overhaul) and Jatco JF011E CVT service literature, a thrust-bearing is relevant to the 2008 Mitsubishi Lancer. Manual-transmission models use a clutch release (thrust) bearing, and all 4B11/4B12 petrol engines use a crankshaft thrust bearing integrated with the main bearings to control end-float. CVT-equipped cars don’t use a clutch release bearing, but they still have the engine’s crankshaft thrust bearing.

For a 2008 Lancer with a manual gearbox, the thrust-bearing most owners talk about is the clutch release bearing. It takes the axial load from the clutch fork and transfers it smoothly to the pressure plate fingers, so the clutch can disengage cleanly. When it’s healthy, gear changes feel neat and the driveline stays quiet. When it’s tired, there’s usually a chirp, squeal, or growl with the pedal pressed, along with a clutch that feels rough or notchy.

Replacement is straightforward but does require removing the gearbox, so it’s smart to fit a complete clutch kit (pressure plate, friction disc, release bearing) at the same time. Many workshops in Australia and New Zealand recommend doing the release bearing with any clutch job, typically somewhere between 120,000 and 200,000 kilometres depending on use. During the job, it’s well worth:

• Lightly greasing the clutch fork pivot and release bearing contact points with a high-temp moly grease.
• Inspecting the input shaft sleeve/guide for wear and the fork for cracks or slop.
• Checking the rear main seal and driveshaft seals while access is easy.
• Inspecting the spigot/pilot bearing if fitted to the specific engine/trans combo.

Tell-tale signs the release (thrust) bearing is on the way out include noise only when the clutch pedal is depressed, a vibration in the pedal, or difficulty selecting gears at a standstill. If the noise is present in neutral with the pedal up and fades when the pedal is pressed, that points more towards an input shaft bearing rather than the release bearing.

Every 2008 Lancer engine also uses a crankshaft thrust bearing to control end float. It isn’t a routine service item, but if there’s excessive fore–aft movement of the crank pulley, or a metallic knock during clutch engagement, an inspection is warranted. Causes of premature thrust wear include riding the clutch, heavy-duty pressure plates with higher clamp loads, or hydraulic issues that keep the release system partially engaged. If wear is confirmed, the engine will need bearing replacement and end-float measurement to factory specs during reassembly.

CVT models don’t have a clutch release bearing, so any driveline noise on those cars should be assessed in terms of CVT service condition, mounts, or ancillary pulleys—while remembering the engine’s crank thrust bearing is still present but rarely needs attention unless there’s a specific fault.

FAQs

Does a 2008 Lancer with CVT have a thrust-bearing?
CVT models don’t have a clutch release (thrust) bearing because there’s no conventional clutch. They do, however, have the engine’s crankshaft thrust bearing, which manages end-float inside the 4B11/4B12 engine and isn’t typically a service item unless there’s a diagnosed issue.

What noise points to a failing clutch thrust-bearing?
If the noise appears only when the clutch pedal is pressed—often a chirp, squeal, or rumble—it’s likely the release bearing. A whine in neutral that disappears when the pedal is pressed usually points to the gearbox input shaft bearing instead.

How long does replacement take and what else should be done?
Expect around 4–7 hours of labour depending on workshop and model. It’s best to replace the full clutch kit, renew gearbox oil, lightly grease the fork pivot, and inspect seals and the guide tube while it’s all apart.
