Parts for your 2001 Holden Commodore-Thrust bearing

2001 Holden Commodore thrust-bearing — what it does and when to replace it

Based on Holden’s VX Series Workshop Manual for manual models and the transmission manufacturers’ documentation (Getrag 5-speed and Tremec T56), a thrust-bearing — commonly called the clutch release bearing — is fitted to 2001 Holden Commodore manuals. The automatic variants (Hydra-Matic 4L60-E per GM service literature) don’t use a clutch thrust-bearing because they run a torque converter instead of a manual clutch. So, the thrust-bearing is relevant to 2001 Commodores with a manual gearbox only.

On manual VX Commodores, the thrust-bearing sits on the gearbox input area and presses on the clutch diaphragm when the pedal’s pushed. Its job is simple but critical: convert the pedal’s movement into smooth, low-friction contact so the clutch can disengage cleanly. Depending on the transmission, this is either a conventional release bearing riding on a fork (common on the Getrag 5-speed) or an internal concentric slave cylinder with an integrated bearing (seen on many Tremec T56 setups). These layouts are documented in the respective Getrag/Tremec service manuals and Holden’s workshop procedures.

Tell-tale signs it’s on the way out include:

• A whirring or growling that appears when the clutch pedal is pressed, then fades when released
• Notchy pedal feel, clutch drag, or difficulty selecting gears when stationary
• Fluid weep at the bellhousing on cars with a concentric slave cylinder

Good practice during servicing is to treat the thrust-bearing as a “while you’re in there” item. If a clutch is being replaced, fit a new quality release bearing (or complete concentric slave cylinder, if that’s the design) at the same time. That advice aligns with Holden’s workshop approach and both Getrag and Tremec service guidance for clutch-overhaul procedures.

What a shop will typically do on a 2001 Commodore manual:

1. Remove the gearbox, inspect the clutch, pressure plate, flywheel, fork/pivot, and guide tube
2. Replace the thrust-bearing and pilot/spigot bearing with the clutch kit
3. If a concentric slave is fitted, replace the unit and bleed the hydraulic system with fresh DOT 4
4. Check end-float and runout specs, then reassemble and road test for noise-free operation

Day to day, there’s no special maintenance beyond keeping the clutch hydraulic fluid fresh and addressing any pedal feel changes early. If the Commodore is an automatic, a clutch thrust-bearing isn’t used, any drivetrain whine or engagement issue should be diagnosed within the torque converter or auto trans, not a release bearing.

Does an automatic 2001 Commodore have a thrust-bearing?

No. The 4L60-E automatic uses a torque converter, so there’s no clutch release (thrust) bearing. If it’s making noise on engagement, the diagnosis is in the converter, pump, or internal bearings — not a clutch bearing.

What noise points to a failing thrust-bearing on a manual VX?

A rumble, growl, or chirp that starts when the clutch pedal is pressed and disappears when it’s released is classic thrust-bearing territory. If the noise is present all the time, look elsewhere (input shaft bearing, diff, or wheel bearings).

Should the thrust-bearing be replaced with the clutch?

Absolutely. With the gearbox out, the bearing (or concentric slave assembly) is cheap insurance. Most reputable clutch kits for the 2001 Commodore include a release bearing and pilot/spigot bearing for exactly this reason.
