Parts for your 2011 Holden Commodore-Thrust bearing

2011 Holden Commodore thrust bearing — what it is, and when it matters

Based on the Holden VE Series II Service Manual (clutch section), plus the Tremec TR-6060 and Aisin AY6 transmission service data, the 2011 Holden Commodore with a manual gearbox uses a hydraulic concentric slave cylinder that integrates the clutch release (thrust) bearing. Parts catalogues from Exedy and Sachs also list this combined CSC/release bearing for VE/2011 Commodore manuals. The Hydra‑Matic 6L50/6L80 automatic transmissions don’t use a clutch thrust bearing because they run a torque converter. Separately, GM Powertrain documentation for the HFV6 and LS-series engines shows crankshaft thrust bearings in the main bearing set, but they’re not a routine service item unless the engine is being rebuilt.

For manual models, the thrust bearing’s job is simple but crucial: it rides the pressure plate’s diaphragm spring when the clutch pedal is pressed, taking axial load and letting the clutch disengage smoothly and quietly. On the 2011 Commodore the bearing lives inside the bellhousing as part of the concentric slave cylinder, so it’s hydraulically actuated and self-centring. When it’s healthy, shifts feel clean, there’s no squeal or rumble with the pedal down, and take-up is consistent.

Because the bearing is integrated with the slave cylinder, it’s standard practice to replace the CSC/release bearing whenever the clutch is replaced. It’s a gearbox-out job, so doing the lot in one hit saves repeat labour. Good workshops will also inspect the flywheel face, replace the spigot/pilot bearing, and check for rear main seal weep. Use the correct spec brake fluid (DOT 4) and bleed the system thoroughly to keep pedal feel crisp.

• Tell‑tale signs: a chirp or whirr with the pedal depressed, clutch drag at a standstill, a notchier first/second shift, or hydraulic fluid loss around the bellhousing.
• Fitment tips: avoid contaminating the friction disc, pre‑fill the CSC as directed in the service manual, and torque fasteners to spec.
• Service habit: flush clutch hydraulics when you do the brakes, heat and moisture are rough on seals and bearings.

If the car’s an auto, there’s no clutch thrust bearing to worry about. Any driveline noise with an automatic is more likely torque‑converter, flexplate, or accessory related. Engine crankshaft thrust bearings exist on all variants, but unless there’s measurable end‑float or unusual clutch/torque‑converter load issues, they’re not touched during routine servicing.

Popular questions

Does my 2011 Commodore have a thrust bearing?
Manual models (Aisin AY6 V6 and Tremec TR‑6060 V8) do — it’s the release bearing built into the concentric slave cylinder. Automatics (6L50/6L80) don’t have a clutch thrust bearing because they use a torque converter. All engines have crankshaft thrust bearings internally, but they’re not a normal service item.

What are the symptoms of a failing thrust bearing/CSC?
Listen for a chirp or whirr when the clutch pedal is pressed, rough or notchy shifts, clutch drag when selecting first, or hydraulic fluid seepage at the bellhousing. Pedal feel that gets spongy or inconsistent can also point to an issue.

When should it be replaced?
Replace the CSC/release bearing whenever you replace the clutch. It’s a gearbox-out job, so doing the bearing, spigot/pilot bearing, and inspecting the flywheel at the same time is the smart play. If symptoms show up earlier, don’t wait — address it to avoid collateral clutch or gearbox wear.
