Parts for your 2016 Holden Astra-Centre bearing

2016 Holden Astra centre-bearing: is it used?

Based on GM Global Service Information for the BK (Astra K) platform and Holden’s Electronic Parts Catalogue for the 2016–2017 Astra, a traditional tailshaft centre-bearing isn’t fitted to this model. The Astra is a front‑wheel‑drive hatch with a transaxle, two front drive shafts and CV joints—there’s no propeller shaft running the length of the car, so there’s no need for a centre support bearing as seen on rear‑ or all‑wheel‑drive vehicles. Opel/GM workshop literature instead details a right‑hand intermediate (jack) shaft with a carrier/support bearing mounted to the engine block, which some people casually call a “centre-bearing”, but it serves a different purpose to the tailshaft type.

Why it’s not used comes down to layout. With the gearbox and differential integrated up front, power goes straight to short drive shafts. There’s no long tailshaft to support, so a centre-bearing isn’t relevant on the 2016 Holden Astra. The only “support bearing” you’ll encounter is the intermediate shaft carrier bearing on the right‑hand side, designed to balance left/right shaft lengths and help curb torque steer—again, not a tailshaft centre-bearing.

If someone’s chasing a “centre-bearing” because of vibration or a hum at speed in a 2016 Astra, the likely culprits are elsewhere. Common checks include:

• Front wheel bearings and tyres (cupping, out‑of‑round, imbalance)
• CV joints/drive shafts (clicking on lock, rumble under load)
• Engine and transmission mounts (shudder on take‑off, excessive movement)
• Right‑hand intermediate shaft support bearing (growl that changes with throttle)

That intermediate shaft support bearing isn’t a scheduled service item, it’s replaced on condition. Telltales include a droning noise between roughly 60–90 km/h that loads and unloads with throttle, or noticeable play when the shaft is supported and gently levered. Replacement involves removing the right drive shaft and carrier bracket and should follow the factory procedure (Astra K/BK workshop manual) for correct torque settings, shaft sealing and bracket alignment. Using quality bearings and confirming wheel balance and alignment after driveline work helps keep the Astra smooth on Aussie and Kiwi roads.

Popular questions about a 2016 Holden Astra centre-bearing

Does a 2016 Holden Astra have a centre-bearing?
Not in the tailshaft sense. The BK Astra doesn’t have a prop shaft, so there’s no tailshaft centre support bearing. It does have a right‑hand intermediate drive shaft with a carrier/support bearing, which some people loosely call a centre-bearing, but it’s a different component and function.

What causes vibration if there’s no centre-bearing?
Most vibration complaints come back to front wheel balance/tyres, worn wheel bearings, tired engine/trans mounts or CV/drive shaft issues. The intermediate shaft support bearing can also drone or rumble when worn, but it’s less common than tyres or wheel bearings.

How can an owner tell if the intermediate shaft support bearing is failing?
Listen for a steady growl that appears around suburban to highway speeds and changes with light throttle. On a hoist, a tech will check for play at the intermediate shaft and inspect the bearing bracket and rubber support. If there’s roughness or movement, replacement following the factory procedure is the go.
