Parts for your 1999 Toyota Caldina-Thrust bearing

1999 Toyota Caldina thrust-bearing — what it is and how to look after it

Based on Toyota’s factory literature and parts catalogues, a thrust-bearing is absolutely relevant to the 1999 Toyota Caldina. The Toyota Electronic Parts Catalogue for ST210/ST215 lists a “Release Bearing Assy, Clutch” for the manual transaxles (Aisin S54 2WD and E56F AWD). The Toyota Caldina (ST210/215) Repair Manual — Clutch section — details inspection and replacement of the release (thrust) bearing. Separately, the 3S‑FE/3S‑GTE Engine Repair Manual specifies crankshaft thrust bearing clearance as part of the main bearing set. So: manual Caldinas use a clutch release/thrust bearing, and all engines use crankshaft thrust bearings. Automatic-trans models don’t have a clutch release bearing, but the engine still has thrust bearings inside.

On a manual 1999 Caldina, the thrust-bearing (also called the clutch release or throwout bearing) sits on the gearbox input shaft collar and presses on the pressure plate’s diaphragm when the clutch pedal’s down. Its job is to let the rotating clutch assembly be pushed smoothly without transferring rotational load to the release fork and hydraulics. When it’s healthy, pedal feel is light and the engagement is drama-free. When worn, you can cop a whirring or growl with the pedal pressed, notchy engagement, or clutch drag at the lights.

As part of sensible servicing, treat the thrust-bearing as a replace-once-you’re-in-there item. Any time the clutch is out — whether for a worn disc, a rear main seal, or gearbox work — fit a new quality bearing (genuine Toyota or reputable OEM such as Aisin), and replace it together with the clutch disc and pressure plate. Lightly grease the release fork pivot and the bearing’s sliding surfaces on the guide collar with a high-temp moly grease, but keep grease off the friction surfaces and the bearing face. Inspect the release fork, pivot ball, input shaft seal, clutch fork boot, and hydraulics (master/slave cylinder) so you don’t have to pull the box again. If you’ve got an AWD ST215, allow extra time as removal is tighter around the transfer case.

• Typical symptoms of a crook thrust-bearing:
  • Noise only when the clutch pedal is depressed
  • Harsh or notchy pedal feel
  • Clutch drag or hard shifting into first/reverse
  • Noise that worsens as the bearing warms up

Toyota’s manuals also note that engine crankshaft thrust bearings aren’t routine service items, they’re checked and renewed during an engine rebuild when axial play is out of spec.

Popular questions about 1999 Toyota Caldina thrust-bearing

Does an automatic 1999 Caldina have a thrust-bearing?
Automatic versions don’t have a clutch release (thrust) bearing because there’s no manual clutch. They still have engine crankshaft thrust bearings inside the block, but those aren’t serviced unless the engine is being rebuilt or there’s abnormal end-float.

How can someone tell if the thrust-bearing is failing on a manual Caldina?
The classic giveaway is noise with the clutch pedal pressed — a whirring, rumble, or chirp that disappears when the pedal’s released. You might also notice a rough pedal feel or trouble selecting gears at a standstill. If the noise is present with the pedal up, look instead at the gearbox input bearing or idlers.

Should a new thrust-bearing be greased during installation?
Don’t pack the bearing itself with grease — it’s pre-lubed. Only apply a light smear of high-temp grease to the release fork pivot, the contact points on the fork, and the bearing’s sliding surface on the input shaft collar. Keep lubricant well clear of the clutch disc and pressure plate face.
