Parts for your 2003 Toyota Wish-Thrust bearing

2003 Toyota Wish thrust bearing — is it actually there?

Short answer: a clutch thrust/release bearing isn’t fitted to the 2003 Toyota Wish. Toyota’s own parts catalogue for the first‑gen Wish (ZNE10G/ANE10G, 2003) shows the model was sold with either the Aisin K110 CVT or the U241E 4‑speed automatic. There’s no manual gearbox listed, so there’s no clutch assembly and therefore no clutch thrust/release bearing to service. This aligns with Aisin’s K110 CVT technical information (torque converter input, no clutch release mechanism) and Toyota transmission documentation for the U241E automatic.

If someone’s chasing a “thrust bearing” for a Wish, they’re usually thinking of the manual clutch release/thrust bearing. Autos and CVTs use a torque converter and internal multi‑plate clutches, so there’s nothing that’s operated by a clutch pedal and no release bearing to make noise when you “press the clutch” — because there isn’t one.

Two other bearings are worth a mention so owners don’t get led astray:

• Engine crankshaft thrust bearing: The 1ZZ‑FE and 1AZ‑FSE engines in the Wish use thrust bearings integrated with the main bearing set to control crankshaft end float. Toyota’s engine repair manuals specify measuring thrust clearance during an engine rebuild, but this isn’t a routine service part. If these wear, you’re looking at engine‑out work, not a quick driveway fix.
• Front strut top mount bearing: The Wish runs MacPherson struts up front. The upper support includes a bearing to let the strut rotate smoothly while steering. Some tradies casually call this a “thrust bearing”. This one is serviceable and commonly replaced with the strut mount if there’s groaning, notchy steering, or a clunk over bumps.

What this means for regular servicing:

1. No clutch thrust/release bearing to replace — it’s not part of the drivetrain on this model.
2. If there’s a whirring or grinding noise that someone reckons is a “thrust bearing”, check the front strut top mounts and the CVT/automatic fluid condition instead.
3. Engine thrust bearings are only inspected during bottom‑end work. Unless there are serious symptoms (abnormal crank end float, metallic debris in oil, harsh axial knock), they’re left alone.

Popular questions

Does a 2003 Toyota Wish have a clutch thrust/release bearing?
No. The 2003 Wish was delivered with a CVT (K110) or a 4‑speed auto (U241E), so there’s no clutch pedal and no release/thrust bearing. Any noise that sounds like a “clutch bearing” won’t be that — look to the transmission, driveline, or suspension instead.

What “thrust bearing” could mechanics be talking about on a Wish?
They might mean the front strut top mount bearing, which allows the strut to turn during steering, or the engine’s internal crankshaft thrust bearing. The strut bearing is a normal service item, the engine thrust bearing is only addressed during a rebuild.

How do you spot a worn strut top bearing on a Wish?
Common tells include notchy or heavy steering at low speeds, a groan when turning the wheel, or a clunk over speed humps and driveway entries. If it’s tired, replace the bearing or complete mount, and consider fresh strut boots and bump stops while you’re in there.
