Parts for your 2009 Lexus Is-Thrust bearing

2009 Lexus IS thrust-bearing: what’s actually fitted

Based on technical sources, a thrust-bearing is relevant on the 2009 Lexus IS only for models fitted with the 6‑speed manual transmission (IS250 GSE20). The Lexus/Toyota Repair Manual for the GSE20 series (Clutch Unit section) details a clutch release (thrust) bearing as part of the manual clutch assembly, and the Toyota Electronic Parts Catalogue lists a “Release Bearing Assembly” for IS250 6MT. Automatic models (A960E/AA80E/AB60-style autos, including IS350 and IS F) use a torque converter and do not have a clutch thrust-bearing. For completeness, the 4GR‑FSE/2GR‑FSE/2UR‑GSE engines do have crankshaft thrust faces integrated in the main bearing set (Engine Repair Manual), but these aren’t service items during routine maintenance. The Lexus New Car Features documentation also shows the IS uses double-wishbone front suspension, so there’s no MacPherson strut top thrust-bearing to service.

For owners of a 2009 IS250 with the 6‑speed manual, the clutch thrust-bearing’s job is simple but vital: it transfers pedal effort smoothly to the pressure plate diaphragm, letting the clutch disengage without noise or graunching. When healthy, it keeps shifts slick and pedal feel consistent. When tired, it’s often the first thing you’ll hear—think a chirp, whirr, or growl that appears when the pedal’s pressed and fades when released.

Best practice during servicing is to treat the thrust-bearing as a “while-you’re-in-there” replacement whenever the gearbox is out. The labour to access it is the same as a clutch job, so fitting a fresh bearing with a full clutch kit is the smart money. Stick with quality OEM-equivalent parts, lightly grease the bearing guide and fork contact points with the specified high-temp moly grease (sparingly), and make sure the clutch hydraulics are properly bled so the bearing isn’t preloaded.

Practical tips for local conditions: avoid riding the clutch in stop‑start city traffic, don’t rest a foot on the pedal during long cruises, and use a clean, decisive pedal action. During the job, have the tech inspect the fork, pivot ball, slave cylinder, and pilot bearing, and check the rear main seal for weeping. The IS250 manual typically runs a dual‑mass flywheel—get it measured for free play and damping, if it’s out of spec, replace rather than resurface. Done right, the new thrust-bearing and clutch package should deliver years and many kilometres of quiet, easy shifts.

• Common symptoms: noise with the pedal depressed, notchy engagement, pedal vibration.
• Typical interval: replace with the clutch—often 120,000–200,000 km depending on use.
• Driving tip: minimise half-clutch on hills, use the handbrake start to save the bearing.

FAQs

Does a 2009 Lexus IS automatic have a thrust-bearing?
No. Auto models use a torque converter, so there’s no clutch thrust-bearing to service. The engine’s crankshaft thrust surfaces exist inside the main bearings, but they’re not routine maintenance parts.

Can the thrust-bearing be replaced on its own?
It can, but it’s not recommended. Because the gearbox has to come out, most techs replace the full clutch kit (pressure plate, disc, release bearing) and inspect the pilot bearing and flywheel at the same time.

What noises point to a bad thrust-bearing on an IS250 manual?
A chirp, squeal, or grinding sound that appears only when the clutch pedal is pressed is classic release bearing noise. If it chatters or the pedal feels rough, book it in for inspection before it damages the pressure plate fingers.
