Parts for your 2017 Holden Astra-Centre bearing

2017 Holden Astra centre-bearing — what’s actually fitted

Based on the Holden/GM Global Service Information for the BK/BL Astra (model year 2017), the Opel Astra K workshop manual, and the Holden Electronic Parts Catalogue for those models, a tailshaft centre-bearing is not fitted to the 2017 Holden Astra sold in Australia and New Zealand. All 2017 Astra hatch (BK) and sedan (BL) variants are front‑wheel drive with a transversely mounted engine and a transaxle. Those technical sources document front drive shafts (left and right) only, there’s no propeller shaft or tailshaft assembly, and therefore no centre-bearing listed or serviced for this vehicle.

Why isn’t a centre-bearing used here? A centre-bearing supports the middle of a long, two‑piece tailshaft on rear‑wheel drive or all‑wheel drive vehicles. The 2017 Astra doesn’t have a tailshaft at all. Instead, it uses two short half‑shafts (CV axles) from the transaxle to the front wheels. On the right‑hand side, there’s an intermediate shaft that’s bolted to the engine block with a carrier bracket, its support is an intermediate shaft carrier bearing, not a tailshaft centre-bearing. The workshop procedures and parts listings for the 2017 Astra cover CV joints, boots, and that intermediate shaft support, but nothing described as a “centre-bearing.”

• Vehicle layout: transverse FWD, no propeller/tailshaft to the rear axle.
• Relevant service items: CV joints/boots, wheel bearings, engine/trans mounts, and the RH intermediate shaft carrier bearing.
• Typical “centre-bearing” symptoms on other cars (driveline shudder) map in the Astra to CV wear, out‑of‑balance wheels/tyres, or a tired intermediate shaft bearing.

So if someone is searching for a 2017 Holden Astra centre-bearing, what they likely need is either a CV shaft assembly, the right‑hand intermediate shaft carrier bearing, or to diagnose vibration from mounts, wheels, or tyres. A technician will road test, check for play in the CV joints, spin the wheels for balance and bearing noise, and inspect the intermediate shaft bracket and bearing for roughness or movement. Any faulty component is replaced as a unit per the Holden/GM procedures, these parts are serviced under Front Drive Axle in the manuals and EPC, not under propeller/tailshaft groups.

FAQs

Does a 2017 Holden Astra have a centre-bearing?
No. Technical documentation for the BK/BL Astra (2017) shows no tailshaft or centre-bearing. It’s a front‑wheel drive setup with half‑shafts and, on the right side, an intermediate shaft with a carrier bearing mounted to the engine block.

What causes driveline vibration on a 2017 Astra if there’s no centre-bearing?
Common culprits are worn CV joints, a failing right‑hand intermediate shaft carrier bearing, out‑of‑balance or damaged wheels/tyres, or perished engine/transmission mounts. A proper inspection will isolate which item is introducing the vibration under load or at certain speeds.

Is there a bearing similar to a centre-bearing on the Astra?
Yes—the right‑hand intermediate shaft carrier bearing. It supports the longer RH driveshaft between the transaxle and the CV joint. If it becomes noisy or loose, it’s serviced under the front drive axle section of the workshop manual and replaced following the specified procedure and torque settings.
