Parts for your 2012 Holden Commodore-Driveshafts

2012 Holden Commodore driveshafts

Driveshafts are absolutely relevant and used on the 2012 Holden Commodore. Technical references such as the Holden VE Series II Service Manual (GMH Service Information), GM Genuine Parts Catalogue listings for “propeller/tailshaft” and “rear drive axle shaft,” and workshop data for VE/VF platforms all specify a two‑piece tailshaft with a centre support bearing, plus independent rear suspension with left and right CV half‑shafts. That means every 2012 Commodore sedan, wagon and ute in the range uses driveshafts to get power to the back wheels.

On this model, there are two key bits people call “driveshafts”: the tailshaft (also called prop shaft) that runs from the gearbox to the rear differential, and the rear axle shafts (CV shafts) that run from the diff to each wheel hub. Together they transfer engine torque smoothly, allow suspension movement, and keep everything spinning true at highway speeds.

As part of routine servicing, it’s smart to inspect the driveshafts every 10,000–15,000 km or at each service interval. Look for split or weeping CV boots on the rear shafts, play in the CV joints, and any sling‑off grease around the inner joints. On the tailshaft, check the centre support bearing for torn rubber, excess movement, or droning noises, and inspect the joints (CV or universal joints depending on variant) for free play and dry, rusty dust—classic signs they’re on the way out. Also scan for dents, missing balance weights, or flange bolt looseness that can cause a vibration under load.

Common symptoms that warrant attention include a clunk on take‑off, a shudder on acceleration, vibration at 80–110 km/h, or a rhythmic clicking from the rear when turning. If replacement is needed, mark flange positions before removal to preserve balance, replace single‑use flange bolts, and torque to spec. It’s good practice to replace a noisy centre bearing with a quality unit rather than just the rubber isolator. After rear CV shaft replacement, check wheel bearing preload where applicable and road‑test for vibration. There’s no set replacement interval—condition and driving style rule—but keeping boots intact and addressing small vibrations early will save bigger dollars down the track.

• Inspect CV boots, joints, and tailshaft centre bearing at each service.
• Chase down any vibration or clunk promptly to avoid collateral damage.
• Use new flange bolts and maintain original orientation on refit.

Popular questions

What are the signs my 2012 Commodore’s driveshafts are worn?
Drivers often notice a shudder on acceleration, a thump when shifting from reverse to drive, or a vibration that appears at certain speeds. Clicking on turns usually points to a rear CV joint, while a steady drone that changes with throttle can hint at a tired centre bearing.

How long do the driveshafts typically last?
There’s no fixed lifespan. With intact CV boots and balanced components, many last well beyond 200,000 km. Frequent towing, hard launches, lowered suspension, or torn boots can shorten that dramatically. Regular inspections and prompt boot repairs extend service life.

Is it safe to keep driving with a vibration from the tailshaft?
It’s not recommended. Ongoing vibration can accelerate wear of the centre bearing, diff pinion seal, and even gearbox mount. If the vibration just appeared, get it checked quickly—often it’s a simple balance, bolt, or joint issue that’s cheaper to fix early.
