Parts for your 2005 Toyota Altezza-Thrust bearing

2005 Toyota Altezza thrust bearing — what it is, and when to sort it

Yes, a thrust bearing is relevant on a 2005 Toyota Altezza equipped with a manual gearbox. In Aussie and Kiwi workshops it’s commonly called the clutch thrust (release) bearing. Technical sources that document its fitment and function include the Toyota Altezza/Lexus IS200 (XE10) repair manual, the Aisin J160 6‑speed transmission service manual, and Toyota’s Electronic Parts Catalogue, all of which list and illustrate the clutch release bearing for manual models. Automatic Altezzas don’t use a clutch thrust bearing (they use a torque converter), though the engine itself does have crankshaft thrust bearings that aren’t a routine service item.

On a manual Altezza, the thrust bearing sits on the clutch fork and presses against the pressure plate’s diaphragm spring when the driver pushes the pedal. Its job is to turn that push into smooth, low‑friction movement so gears can be selected cleanly without shudder or graunching. When it’s healthy, pedal feel is light and quiet, when it’s tired, it’ll let you know.

• Common signs it’s on the way out: chirping or squealing with the clutch pedal depressed, rough or notchy pedal feel, vibration through the pedal, hard shifts, or a rumble that changes when you touch the pedal.

There’s no scheduled interval to replace the thrust bearing, it’s a “replace on condition” part. The smart play is to renew it whenever the clutch is out, as the labour overlaps. A quality clutch kit (cover, disc, thrust/release bearing, and pilot/spigot bearing) saves time and dramas later. Follow the factory torque specs and alignment steps in the Toyota repair manual.

• While you’re in there, check: clutch fork and pivot ball wear, input shaft splines (clean and lightly lubricate), clutch slave cylinder condition, rear main seal seepage, and flywheel surface (resurface or replace if heat‑spotted).

Day‑to‑day, there’s not much to “maintain” on the bearing itself. Good habits are the win: don’t ride the clutch, keep proper pedal free‑play, and bleed the clutch hydraulics if the pedal feels spongy. A tiny smear of high‑temp moly grease on the fork contact points during installation is fine, don’t grease the bearing face.

If the car’s an automatic Altezza, a clutch thrust bearing doesn’t apply. Any axial load control happens inside the auto transmission and via the engine’s crankshaft thrust bearings, which are checked only when an engine is rebuilt or if end‑float issues are diagnosed.

Popular questions about the 2005 Toyota Altezza thrust bearing

Does every 2005 Altezza have a thrust bearing?
Manual models do — it’s the clutch release (thrust) bearing in the bellhousing. Automatic versions don’t have one because they use a torque converter. Regardless of transmission, the engine has crankshaft thrust bearings, but those aren’t routine service items.

How can someone tell if the thrust bearing is failing on their Altezza?
Noises that change when the clutch pedal is pressed are the big clue: chirp, squeal, or rumble. Add in a rough or juddery pedal, hard gear changes, or a whirring at idle that disappears with pedal pressure. If those show up, plan for a clutch‑out inspection and likely bearing replacement.

Should the thrust bearing be greased during installation?
Only at the contact points: a light smear of high‑temp moly grease on the release fork pads, pivot ball, and input shaft splines. Do not grease the bearing’s contact face or over‑grease anything — excess can fling onto the clutch, causing slip or chatter.
