Parts for your 2025 Mitsubishi Triton-Thrust bearing

2025 Mitsubishi Triton thrust-bearing: what’s fitted and how to look after it

Based on Mitsubishi’s technical literature for the sixth‑gen Triton/L200 (MY24–MY25) — including the Service Manual clutch section and the Mitsubishi ASA electronic parts catalogue — manual-transmission variants are fitted with a clutch release bearing (commonly called a thrust-bearing). Automatic Tritons don’t use a clutch thrust-bearing because they run a torque converter. The engine itself also has crankshaft thrust bearings to control end float, but those aren’t routine service items.

On a 2025 Mitsubishi Triton with the 6‑speed manual, the thrust-bearing sits on the gearbox input shaft sleeve and pushes on the clutch pressure plate’s diaphragm via the release fork. Its job is to convert the pedal action into a smooth, axial load so the clutch can disengage cleanly. When it’s healthy, gear changes feel slick and quiet, when it’s worn, the driver may notice noise or a rough pedal feel.

Typical signs it’s on the way out include:

• A chirp, squeal, or rumble that appears when the clutch pedal is pressed and fades when released
• Notchy or pulsing pedal feel, or clutch engagement that’s inconsistent
• Vibration through the pedal under load

There’s no scheduled interval to replace the thrust-bearing, it’s usually renewed whenever the clutch is out for service. Best practice, as echoed in Mitsubishi’s service procedures, is to replace it as part of a complete clutch kit. While the gearbox is out, also inspect the release fork, pivot ball, guide tube, spigot/pilot bearing, and the rear main seal. Lightly grease the input shaft splines and the fork pivot with the specified high‑temp lubricant, but never grease the bearing’s contact face.

Good habits go a long way: don’t ride the clutch at lights, keep the foot off the pedal between shifts, and make sure any pedal free play is within spec after hydraulic work. If the vehicle sees heavy towing or off‑road work, pay extra attention to any new pedal noise. Once a bearing gets noisy, it won’t heal itself — plan the repair before it takes out the pressure plate fingers.

For automatic 2025 Tritons, there’s no clutch thrust-bearing to service, focus instead on transmission fluid condition per Mitsubishi’s maintenance schedule.

Popular questions about the 2025 Triton thrust-bearing

Does a 2025 Triton with auto have a thrust-bearing?
No. Automatic variants use a torque converter and don’t have a clutch release (thrust) bearing. Only the manual models have a thrust-bearing in the clutch release mechanism.

What noise points to a failing thrust-bearing?
A chirp, squeal, or rumble that starts when the clutch pedal is pressed and stops when it’s released is the classic sign. If the noise occurs with the pedal up and disappears when pressed, that’s more likely an input shaft or spigot/pilot bearing.

When should the thrust-bearing be replaced on a Triton?
It’s typically replaced whenever the clutch is serviced or if it becomes noisy or rough. Because gearbox removal is required, most workshops fit a complete clutch kit (pressure plate, disc, release bearing, and often spigot/pilot bearing) in one go.
