Parts for your 2019 Holden Commodore-Universal joints

2019 Holden Commodore universal joints (U-joints) — are they used?

For the 2019 Holden Commodore (ZB), “universal joints” in the classic cross-type/Cardan sense aren’t a fitted or serviceable part. This generation is based on the Opel Insignia B with a transverse engine layout. Both the front-wheel drive models and the all-wheel drive variants use constant velocity (CV) joints rather than traditional U-joints.

Technical documentation backs this up. GM Service Information (ZB Commodore/Insignia B) describes the half-shafts as using Rzeppa and tripod CV joints, and outlines the AWD propeller shaft as a sealed, two-piece assembly with a centre support bearing and CV joints at its ends, serviced as a complete unit rather than by replacing individual joints. The Holden/GM Electronic Parts Catalogue for ZB lists the propeller shaft as an assembly and does not list separate U-joints. On AWD models, the rear drive is handled by GKN’s Twinster torque-vectoring module, a system typically paired with CV-jointed propshafts for smooth torque delivery and refined NVH.

Why no U-joints here? It comes down to packaging and refinement in a modern, FWD-based platform:

• CV joints deliver true constant velocity through larger operating angles, which suits transverse layouts and AWD torque transfer without the speed fluctuations of a Cardan joint.
• Noise, vibration and harshness are lower with CVs, aligning with the Commodore’s ride and refinement targets.
• Service strategy: shafts are sealed-for-life assemblies, maintenance focuses on inspection rather than periodic greasing or joint replacement.

What owners should do instead of chasing U-joints: keep an eye on CV boots for splits or grease fling, listen for clicking on full lock (front CVs), and watch for driveline vibration or droning that could hint at a worn propshaft centre bearing on AWD cars. If a joint or the AWD propshaft is worn, the correct repair is usually replacement of the complete shaft assembly as per GM SI and parts catalogue guidance.

Popular questions

Does a 2019 Holden Commodore have universal joints?
For this ZB model, no traditional serviceable U-joints are fitted. It uses constant velocity joints on the front drive shafts, and AWD versions have a sealed propshaft with CV joints and a centre bearing. There aren’t separate U-joints listed in the Holden/GM parts catalogue for this car.

How are driveline joints serviced on a 2019 Commodore?
They’re generally not serviced individually. Workshop guidance from GM SI calls for inspection of CV boots, noise/vibration checks, and replacement of the complete driveshaft or propshaft assembly if wear or damage is found. There’s no routine greasing of U-joints because there aren’t any greaseable Cardan joints on this model.

What symptoms point to joint or propshaft issues on AWD Commodores?
Owners might notice vibration under load or at certain speeds, a droning noise from the tunnel area (possible centre bearing wear), or thumps on take-off. Front CV issues typically show up as clicking on full-lock turns or grease flung around a split boot. Diagnosis follows GM SI procedures and usually ends with replacing the affected assembly.
