Parts for your 2012 Holden Commodore-Universal joints

2012 Holden Commodore universal joints — used or not?

Short answer: traditional, serviceable universal joints aren’t used on the 2012 Holden Commodore (VE Series II). The factory tailshaft is a two‑piece assembly that uses a front rubber flex coupling (guibo), a centre support bearing, and a constant velocity (CV) joint at the rear, rather than greasable uni joints. This layout is shown in the Holden VE Series Workshop Manual (Driveline – Propeller Shaft), GM Global Service Information (GMSi) procedures, and backed by GM/ACDelco parts catalogues that list CV joints and flex couplings for VE models, not universal joints. Driveline specialists (e.g., Hardy Spicer/Dana technical bulletins) also describe VE’s move to CV‑based shafts to reduce NVH and improve smoothness.

Why no universal joints on a 2012 Commodore? Holden engineered the VE platform for lower noise, vibration and harshness, better high‑speed manners, and slicker shifting under load. A CV joint maintains constant rotational velocity through angles, so it delivers smoother torque than a single‑cardan uni joint. Pair that with a rubber flex disc to cushion shock loads and you get fewer driveline clunks and less cabin buzz. The design is sold as a balanced assembly and is largely “fit and forget”, which also aligns with modern servicing philosophies—replace the component or complete shaft when worn, rather than periodic greasing.

So while someone might go hunting “2012 Commodore universal joints”, what they actually need to service are the components Holden did fit:

• Front rubber flex coupling (guibo)
• Centre support bearing
• Rear CV joint (or full tailshaft assembly)

Tell‑tale signs it’s time to act include a take‑off shudder, a thump or clunk on gear changes, or a persistent vibration at highway speeds. During replacement, align marks on the flanges, torque bolts to spec, and keep the shaft’s orientation to preserve balance. If the shaft’s been separated or shows dents, consider professional balancing or a complete replacement assembly. Quality parts matter here—OE, OEM, or reputable driveline brands are worth the coin. And if there’s any diff or transmission mount sag, fix that at the same time to protect the new parts.

Popular questions

Does a 2012 Holden Commodore have universal joints?
No—VE Series II models use a two‑piece tailshaft with a flex coupling at the front and a CV joint at the rear. There are no serviceable uni joints in the factory setup, which is why parts catalogues list CV kits and guibos rather than uni joints for this year.

What’s usually causing driveline vibration if there are no uni joints?
Most commonly a worn rear CV joint, cracked or softened front flex disc, or a tired centre support bearing. Engine and transmission mounts can add to the shake too. A quick inspection of the coupling for cracks and the centre bearing for play usually points in the right direction.

Can universal joints be retrofitted to a VE tailshaft?
It’s not recommended. The shaft is designed and balanced around a CV/flex‑disc system. Converting to uni joints alters geometry and NVH, and will often introduce vibration unless the entire assembly is re‑engineered and rebalanced by a driveline specialist.
