Parts for your 2023 Mitsubishi Triton-Thrust bearing

2023 Mitsubishi Triton thrust-bearing

Based on technical references, a thrust-bearing (better known as the clutch release bearing) is fitted to 2023 Mitsubishi Triton models equipped with the 6‑speed manual gearbox. The Mitsubishi MR Triton Workshop Manual (Group 21A – Clutch) diagrams the release/thrust bearing as part of the clutch release mechanism, and the Mitsubishi Motors ASA electronic parts catalogue lists a clutch release bearing for MR Triton VINs with manual transmission. Mitsubishi’s MY23 Triton specification sheets also confirm manual variants in the line-up. Automatic models don’t use a clutch release bearing, although the engine still has crankshaft thrust washers that aren’t a service item in normal maintenance.

On a manual 2023 Triton, the thrust-bearing’s job is to smoothly transfer pedal force via the fork/slave cylinder to the clutch pressure plate diaphragm. It spins only when the clutch pedal’s pressed, keeping things quiet and silky when shifting or selecting gears at the lights. If it gets dry or worn, it can chirp, squeal, or feel rough underfoot.

It’s not a routine service item, it’s typically replaced whenever the clutch is done, because the gearbox has to come out to access it. Smart owners bundle it with a full clutch kit (pressure plate, friction disc, release/thrust bearing, and usually a pilot bearing/bush) to save on labour and come away with a fresh, matched set.

Signs it’s time to look at the thrust-bearing:

• Noise that starts the moment the clutch pedal is depressed (chirp, whirr, squeal)
• Notchy or inconsistent pedal feel when disengaging the clutch
• Vibration through the pedal that changes with pedal position

Good habits help it last: don’t sit at lights holding the clutch in, use neutral and release the pedal. Make sure clutch free play and hydraulic operation are within spec during regular services. If the box is out for any reason (clutch, rear main seal, or gearbox work), it’s cheap insurance to replace the thrust-bearing at the same time. When fitting, technicians should check the fork pivot and guide tube for wear, lightly lube the input shaft splines with the specified high‑temp grease, and keep grease well away from friction surfaces. For utes that tow, carry heavy loads, or work off‑road, expect more frequent clutch inspections, as heat and dust accelerate wear.

For automatic Tritons, thrust-bearing chatter isn’t a thing—any driveline noise will have a different cause, so diagnostics head elsewhere.

Popular questions

Does a 2023 Triton with an automatic have a thrust-bearing?

No. Automatics don’t use a clutch release (thrust) bearing. They use a torque converter, so any noise when stationary with the foot on the brake isn’t related to a clutch bearing. The engine still has internal thrust washers, but they’re not serviced in normal maintenance.

How long should a Triton’s thrust-bearing last?

Typically the life of the clutch—often 100,000 to 200,000 km—depending on driving style, towing, terrain, and traffic. Riding the clutch, holding the pedal at lights, or frequent hill starts will shorten its life.

Can the thrust-bearing be replaced without changing the clutch?

Yes, but it’s rarely cost‑effective. Because the gearbox has to come out, most workshops recommend a full clutch kit while they’re in there, avoiding duplicated labour and ensuring all mating parts wear in together.
