Parts for your 2018 Toyota Hilux-Thrust bearing

2018 Toyota HiLux thrust (release) bearing — what it does and when to replace it

Technical sources identify a thrust-bearing (also called the clutch release bearing) on manual-transmission 2018 Toyota HiLux models, but not on automatics. This is confirmed in Toyota service literature for the N80 HiLux clutch system (Toyota TIS: CL – Clutch, Release Bearing) and by clutch manufacturers listing a release/thrust bearing in their HiLux kits (e.g., Exedy Australia and Aisin catalogues). Note: the engine itself also uses crankshaft thrust bearings inside the bottom end, but those are not routine service items.

On a manual HiLux, the thrust-bearing’s job is simple but critical. When the driver presses the clutch pedal, hydraulic force moves the clutch fork, which presses the release (thrust) bearing into the pressure plate’s diaphragm spring. That cleanly disconnects the engine from the gearbox so gears can be selected without graunching. The bearing must run smoothly and quietly under axial load while spinning at engine speed whenever the pedal’s down.

Because it works hard and lives in a hot, dusty place, the bearing is a sealed, non-serviceable part. It’s designed to be replaced whenever the clutch assembly is renewed. Most HiLux utes will see a clutch service at anywhere from 120,000 to 220,000 kilometres depending on load, towing, and driving style. If the driver rests a foot on the pedal or does lots of stop–start with a load on board, expect a shorter life.

Common signs of a crook thrust-bearing include a chirp, whirr or squeal only when the clutch pedal is depressed, pedal roughness or pulsing, and occasional difficulty selecting first or reverse. If the noise disappears when the pedal is released, the bearing is usually the prime suspect. Ignoring it can score the pressure plate fingers and lead to a heavier, notchy pedal feel.

Replacement involves removing the gearbox, so it’s smart to do the lot in one go: clutch plate, pressure plate, release (thrust) bearing, spigot/pilot bearing, and inspect the fork, pivot ball, and input shaft sleeve/guide tube. Use the specified high-temp moly grease sparingly on contact points only, never contaminate the friction surfaces. Bleed the hydraulic system, check pedal feel, and road test for clean engagement and no noises.

• Helpful habits: avoid riding the clutch, keep hold times at the lights short (neutral and clutch out is kinder), and don’t slip the clutch on long hill starts with a heavy trailer.
• Automatics: the 2018 HiLux with auto has no clutch thrust-bearing, it uses a torque converter instead.

Popular questions about 2018 Toyota HiLux thrust-bearings

Does every 2018 HiLux have a thrust-bearing?
Manual models do — it’s the clutch release bearing. Automatic models don’t, as they use a torque converter. Toyota’s N80 HiLux service information and aftermarket clutch kits list the release/thrust bearing for manuals only.

How long should a HiLux thrust-bearing last, and can it be replaced on its own?
With sensible driving, many last well past 150,000 km. It can technically be replaced on its own, but because the gearbox has to come out, most techs recommend doing the full clutch kit (disc, pressure plate, thrust-bearing, pilot bearing) at the same time to save labour and avoid repeat pull-outs.

What noises point to a failing thrust-bearing?
Listen for a chirp, squeal, or grinding that appears only when the clutch pedal is pressed, and disappears when it’s released. A rough or vibrating pedal can also hint at bearing wear. If those symptoms show up, plan a clutch inspection before it escalates.
