Parts for your 2015 Holden Commodore-Driveshafts

2015 Holden Commodore driveshafts

Based on the Holden VF Series (2013–2017) Service Manual – Driveline/Axle section, GM Global Service Information, and the Holden/ACDelco Electronic Parts Catalogue, the 2015 Holden Commodore is rear‑wheel drive and is fitted with a two‑piece propeller shaft (tailshaft) plus independent rear axle shafts with CV joints. So driveshafts are absolutely relevant on this model—there’s a tailshaft carrying torque from the transmission to the differential, and rear CV half‑shafts delivering it to the wheels.

On the VF Commodore, the tailshaft’s job is simple but crucial: transmit engine torque smoothly to the rear diff while coping with body movement and suspension travel. A centre support bearing and flexible rubber couplings (often called giubos) help control vibration and harshness. From the diff outward, the rear CV driveshafts manage angular changes as the independent rear suspension moves, keeping things quiet and planted even over rough Kiwi and Aussie roads.

For servicing, most workshops check the driveline every 20,000–30,000 km. The big items to watch are cracked or perished giubo couplings, play in the centre bearing, loose flange bolts, and torn CV boots that can fling grease. Owners who’ve lowered their Commodore, tow regularly, or run higher‑output SS/HSV packages should be extra fussy—steeper angles and extra torque speed up wear.

• Common signs it’s time for attention:
  • Shudder or vibration on take‑off or at highway speeds
  • Clunk when selecting Drive or when lifting off/on throttle
  • Hum or drone from the tunnel area (centre bearing)
  • Grease spray around a rear hub (torn CV boot)

Replacement is straightforward for a trained tech: mark the tailshaft orientation, support the exhaust and heat shields as needed, then remove and refit with new self‑locking hardware where specified. Giubo bolts and nuts are typically single‑use, torqueing to spec matters to avoid imbalance. Rear CV shafts should be replaced if boots are split and joints feel gritty or have excessive play—rebooting early can save the joint if caught in time.

After any driveline work, a road test for vibration across the rev and speed range is smart. If the vehicle’s been modified (lowered springs, big power), an upgraded coupling or heavy‑duty tailshaft can be worthwhile insurance for long‑haul reliability.

Popular questions about 2015 Holden Commodore driveshafts

Does the 2015 Commodore have CV driveshafts at the front?
No. The VF Commodore is rear‑wheel drive, so there are no front CV driveshafts. It uses a tailshaft from the transmission to the rear differential and CV half‑shafts only at the rear wheels.

How often should the tailshaft couplings and centre bearing be replaced?
There’s no fixed kilometre interval—replace on condition. Many cars run well past 120,000–200,000 km, but heat, load, and mods can shorten life. Regular inspections for cracks in the giubo, bearing play, and vibration keep surprises away.

Can a vibrating tailshaft damage other components?
Yes. Persistent vibration can accelerate wear in the transmission output seal, differential pinion bearings, and even fatigue exhaust mounts. Sorting vibration early protects the rest of the driveline and keeps the cabin calm.
