Parts for your 1998 Daihatsu Terios-Thrust bearing

1998 Daihatsu Terios thrust-bearing: what it is and what to do with it

Technical verdict: a thrust-bearing is relevant to the 1998 Daihatsu Terios. Manual-transmission models use a clutch release (thrust) bearing within the clutch assembly, and the engine uses crankshaft thrust washers to control end-float. Automatic-transmission Terios models don’t have a clutch thrust-bearing because there’s no manual clutch to operate, though they still have crankshaft thrust control inside the engine.

References to technical sources: Daihatsu Terios J100/J102 Workshop Manual (Clutch/CL section) details the clutch release bearing’s role, inspection and replacement procedure. The Daihatsu HC‑EJ and K3‑VE Engine Repair Manuals (Engine/EM section) specify crankshaft end-float and thrust washer location at the centre main bearing. The Daihatsu Electronic Parts Catalogue (J100 series) lists the clutch release bearing as a service part for 5‑speed manual variants.

On a 1998 Terios with a manual box, the thrust-bearing sits on the clutch release fork and slides on the gearbox snout. When the driver presses the pedal, it pushes on the pressure plate’s diaphragm spring, letting the clutch disc freewheel so gears can be shifted smoothly. It cops plenty of load and spins only when the pedal’s down, so it’s quiet when healthy and gets grumbly or squealy when worn—especially with the clutch depressed.

Servicing advice is straightforward: replace the thrust-bearing any time the clutch is out, ideally as part of a complete clutch kit (disc, pressure plate, release bearing, and pilot bearing/bush). It’s a false economy to reuse an old bearing once the gearbox is already out. During the job, the mechanic should lightly grease the bearing carrier snout and the fork contact points with a high-temp moly grease, keeping lubricant well away from the friction surfaces. They’ll also check the fork pivot, guide tube, and input shaft splines for wear, and verify clutch cable free play or hydraulic adjustment per the workshop manual. On the Terios’s 4WD layout, gearbox and transfer case removal is a bigger task, so planning a full clutch refresh makes sense while access is open.

If the vehicle is an automatic, there’s no clutch thrust-bearing to service. Any “thrust” component then refers to the engine’s internal thrust washers, which aren’t routine service items and are addressed only during an engine overhaul or if end-float is out of spec.

Popular questions

How do you know the thrust-bearing is failing on a 1998 Terios?
Common signs include a whirring, chirping or growling noise that appears when the clutch pedal is pressed and disappears when it’s released. Pedal feel can also turn notchy. If the noise is present with the pedal up, that’s more likely an input shaft or pilot bearing issue.

Should the thrust-bearing be replaced on its own or with a full clutch kit?
Best practice is to replace it with a complete clutch kit while the gearbox is out. Labour is the biggest part of the bill on the Terios’s 4WD setup, so fitting a new pressure plate, disc, release bearing and pilot bearing/bush together saves doing the job twice.

Does an automatic 1998 Terios have a clutch thrust-bearing?
No. Automatic models don’t use a clutch release bearing. They do have engine crankshaft thrust washers internally, but those aren’t periodic service items and only come into play during engine repair or if end-float checks fail.
