2007 Toyota Vitz/Yaris Thrust Bearing

Based on Toyota’s P9-series Repair Manual for the Vitz/Yaris (KSP90/NCP90/NCP91/SCP90) and the Toyota Electronic Parts Catalogue for the 5‑speed manual transmission models, this vehicle is fitted with a clutch release (thrust) bearing on manual variants. Aisin’s clutch kit documentation for these models also specifies a release bearing as part of the set. Automatic models (Aisin U340 series) do not use a clutch thrust bearing, and the engine’s crankshaft thrust washers are internal components not serviced during routine clutch work.

For a 2007 Toyota Vitz/Yaris with a manual gearbox, the thrust bearing (often called the clutch release or throwout bearing) is the sealed bearing that rides on the gearbox input sleeve and presses on the clutch diaphragm spring when the pedal is pushed. Its job is simple but critical: translate pedal effort into smooth, low‑friction movement so gears select cleanly and the clutch disengages without complaint.

While it’s sealed and not a scheduled maintenance item, the thrust bearing lives a hard life. Typical signs it’s on the way out include a whirring or growling noise with the clutch pedal depressed, a change in pedal feel, or notchy engagement. If noise changes as the pedal is feathered, that’s a strong clue.

Any time the clutch is out, it’s smart practice to replace the thrust bearing. Most reputable clutch kits for the 2007 Vitz/Yaris include a new friction disc, pressure plate, and release bearing, and that’s the way to go. Gearbox removal is required, so saving a few dollars by reusing an old bearing is false economy.

• Service tips the techs like: lightly lubricate the clutch fork pivot and contact points with a high‑temp moly grease, keep grease off the bearing face and friction surfaces.
• Inspect the guide tube, fork, and clip for wear, replace if sloppy.
• Check the spigot (pilot) bearing in the crank, rear main seal, and gearbox input seal while access is easy.
• Resurface or at least inspect the flywheel, glaze and hot spots shorten clutch life.
• Bleed/adjust the clutch hydraulics if equipped, a tidy pedal feel protects the new bearing.

Driving style matters. Lots of stop‑start or resting a foot on the pedal can shorten bearing life. Treated right, the new thrust bearing will quietly clock up the kilometres with the rest of the clutch.

• Does a 2007 Vitz/Yaris automatic have a thrust bearing?

No. The automatic uses a torque converter, so there’s no clutch release (thrust) bearing. The engine does have crankshaft thrust bearings inside, but they’re unrelated to clutch operation and aren’t serviced during normal transmission work.

• What are the common signs the thrust bearing needs replacing?

A rumble, whirr, or chirp that appears when the clutch pedal is pressed and disappears when released is classic. You might also feel a rough or notchy pedal, or notice cleaner shifts once the bearing and clutch are renewed.

• Can the thrust bearing be replaced without a full clutch kit?

It can, but it’s not recommended. Because the gearbox has to come out, most workshops fit a full kit (disc, pressure plate, release bearing) and inspect the flywheel and spigot bearing at the same time to avoid doing the job twice.
