Parts for your 2007 Toyota Ist-Thrust bearing

2007 Toyota ist thrust-bearing — what’s fitted and how to look after it

Based on Toyota’s Electronic Parts Catalogue (EPC) for the 2007 ist (NCP110/NCP115 platform, same underpinnings as Scion xD/Urban Cruiser) and the Toyota 1NZ‑FE engine and transaxle repair manuals, a thrust-bearing is indeed used on manual-transmission models — specifically the clutch release (thrust) bearing in the C5x 5‑speed transaxle. Automatic/CVT variants don’t use a clutch release/thrust bearing because they run a torque converter, though the engine still has crankshaft thrust bearings integrated into the main bearings, which aren’t routine service items.

For a 2007 Toyota ist with a manual ’box, the thrust-bearing (commonly called the release or throw‑out bearing) sits on the gearbox input shaft and presses on the clutch pressure plate fingers when the clutch pedal is pushed. Its job is simple but critical: let the rotating clutch assembly be smoothly disengaged while the pedal effort is transmitted through a non‑spinning bearing. When healthy, gearchanges are silky and quiet. When it’s on the way out, owners may hear a whirring or squeal with the pedal down, feel a bit of grumble through the pedal, or notice clutch take‑up getting notchy.

Best practice in Australia and New Zealand is to treat the thrust-bearing as a consumable bundled with a clutch kit. Any time the clutch is out — whether for a worn disc or a leaking rear main seal — the bearing should be replaced. It’s low extra cost compared with the labour of pulling the gearbox. A competent technician will also:

• Lightly lubricate the release fork pivot and bearing contact points with a high‑temp moly grease (no over‑greasing).
• Inspect the input shaft sleeve/guide tube for scoring, replace if worn to prevent rapid new‑bearing noise.
• Check the release fork for cracks and correct return spring tension.
• Verify clutch hydraulic operation and bleed if the pedal feel is spongy or engagement point is inconsistent.

Longevity varies with driving — lots of stop‑start and clutch riding shortens life — but many release bearings last 120,000–200,000 km when the driver fully releases the pedal between shifts and avoids holding the car on the clutch at lights. If noise is present only with the pedal depressed, it’s a strong hint the thrust-bearing is the culprit. Sorted promptly, it prevents collateral wear to the pressure plate fingers and the guide tube, saving a second go at the job down the track.

Does an automatic 2007 Toyota ist have a thrust-bearing?

No clutch thrust/release bearing is used on automatic or CVT versions because they use a torque converter instead of a manual clutch. The engine still has crankshaft thrust bearings inside the block, but these are not serviced unless the engine is rebuilt.

How long should the thrust/release bearing last on a 2007 ist?

With sensible driving, many last 120,000–200,000 km or more. Frequent stop‑start, riding the clutch, or holding the car on hills with the pedal can shorten life. Replace it whenever the clutch is out to avoid paying labour twice.

Can a noisy thrust-bearing damage other parts?

Left as‑is, a rough bearing can chew into the pressure plate fingers, mark the input shaft guide tube, and cause shuddery engagement. Fixing it early usually limits repairs to a standard clutch kit and tidy-up.
