Parts for your 2001 Lexus Is-Thrust bearing

2001 Lexus IS thrust bearing — what it is and when it matters

Based on the Lexus IS (XE10) factory repair literature and Toyota’s Electronic Parts Catalogue, a thrust bearing (also called a clutch release bearing) is fitted to 2001 Lexus IS manual models (e.g., IS200 with the W55 5‑speed). The 2001 IS300 in many markets was automatic-only (A650E), so it doesn’t use a clutch release bearing. Both the 1G‑FE and 2JZ‑GE engines do have crankshaft thrust bearings/washers, but those aren’t typical service items during regular maintenance.

For a 2001 Lexus IS with a manual ‘box, the thrust bearing is the little hero that lets the clutch disengage smoothly. Press the pedal and the bearing rides the clutch fork to push on the pressure plate fingers, taking the load while everything keeps spinning. When it’s healthy, gear changes feel buttery, when it’s tired, things get noisy and a bit rough around the edges.

Owners often first notice a chirp, squeal, or rumble with the clutch pedal depressed. A gritty pedal feel, clutch shudder, or difficulty selecting gears can also point to a release bearing that’s past its best. Because the bearing lives deep inside the bellhousing, it’s not a routine lube-and-go item—replacement is the go-to fix, usually done when the clutch is out.

• Best practice is to replace the thrust bearing whenever fitting a new clutch kit.
• Use quality OE or reputable aftermarket parts, cheap bearings can get noisy quickly.
• Lightly grease only the contact points (fork pivot, bearing carrier/guide tube) with a high-temp moly grease—keep any grease away from the clutch friction surfaces.
• Inspect the clutch fork, pivot ball, guide tube, and spigot/pilot bearing, replace if worn.
• Check the gearbox input shaft seal and engine rear main seal while you’re in there—any leaks will contaminate the new clutch.

There’s no fixed kilometre interval for thrust bearing replacement, it’s condition-based. Habits help, though: don’t ride the clutch at lights, keep the pedal fully up between shifts, and ensure the hydraulic system is bled and leak-free. After installation, torque everything to spec per the Lexus manual, align the clutch correctly, and bed it in gently over the first few hundred kilometres for a quiet, drama-free result.

If the vehicle is an automatic 2001 IS, there’s no clutch release (thrust) bearing in the driveline. Any noise with the selector in Drive or Neutral is more likely from the torque converter, front pump, or ancillary components, not a thrust bearing. Engine crank thrust bearings rarely require attention unless there’s abnormal crank end-float or oiling concerns.

• Is a noisy clutch pedal always the thrust bearing?
• Does an automatic 2001 Lexus IS have a thrust bearing to service?
• What else should be replaced with the thrust bearing on a manual 2001 IS?

Is a noisy clutch pedal always the thrust bearing?
Not always. A chirp or squeal with the pedal depressed often is the release (thrust) bearing, but a dry spigot/pilot bearing, worn fork pivot, or contaminated clutch can sound similar. A good check is whether the noise changes only when the pedal is pressed, if so, the release bearing is a prime suspect.

Does an automatic 2001 Lexus IS have a thrust bearing to service?
No clutch release bearing in the auto. The A650E automatic uses a torque converter, so there’s nothing to service that’s equivalent to a manual’s thrust bearing. The engine still has crankshaft thrust washers, but they’re not a routine service item.

What else should be replaced with the thrust bearing on a manual 2001 IS?
Commonly: clutch disc, pressure plate, spigot/pilot bearing, and the release fork pivot if worn. It’s wise to inspect and replace the gearbox input shaft seal and engine rear main seal if there’s any hint of leakage. Doing it all together saves paying for gearbox removal twice.
