Parts for your 2023 Mazda 3-Centre bearing

2023 Mazda 3 centre-bearing: is it used on this model?

Short answer: for Australian and New Zealand–delivered 2023 Mazda 3 models, a centre-bearing isn’t fitted or required. The 2023 Mazda 3 sold locally is front‑wheel drive (FWD) across the range, so there’s no long tailshaft/propshaft running down the car that would need a centre support bearing. Centre-bearings are a feature of two‑piece propshafts on longitudinal rear‑wheel drive or all‑wheel drive layouts.

Why that matters: in a typical FWD setup like the BP‑series Mazda 3, the engine and transaxle sit transversely and drive the front wheels via two short drive shafts. There’s no centre-bearing in that arrangement. Some FWD cars, including the Mazda 3, use a right‑hand intermediate shaft with a carrier/support bearing bolted to the engine block to balance drive shaft lengths — but that’s not the same thing as a tailshaft centre-bearing.

• Local spec: 2023 Mazda 3 (AU/NZ) is FWD only — no propshaft, no centre-bearing.
• What a centre-bearing does: supports a two‑piece propshaft in RWD/AWD vehicles to control vibration and shaft whip at speed.
• What the Mazda 3 actually has: two front drive shafts, many variants include a right‑hand intermediate shaft with a support bearing (often called an intermediate or carrier bearing), not a centre-bearing.

Technical sources referenced: Mazda Australia and Mazda New Zealand 2023 Mazda 3 specifications list FWD across the range, the Mazda BP Workshop Manual details a propeller shaft and centre bearing only for AWD variants (not sold locally) and separately describes the front drive shaft intermediate shaft and bearing for FWD vehicles, general driveline texts (e.g., OEM service manuals and automotive engineering handbooks) define centre support bearings as components of multi‑piece propeller shafts, not front transaxle layouts.

So if someone’s told there’s a “centre-bearing” to replace on a 2023 Mazda 3 in Australia or New Zealand, they’re probably thinking of a different part. If there’s a rumbling or droning from the front, especially on throttle, a technician will usually check the right‑hand intermediate shaft support bearing, the CV joints, engine/trans mounts, and tyres. For grey‑import AWD Mazda 3s (from markets where AWD is offered), a centre-bearing can indeed exist on the propshaft — but that’s a different driveline to local cars.

• Does a 2023 Mazda 3 have a centre-bearing in Australia or New Zealand?
  No. Local 2023 Mazda 3 models are FWD, so there’s no propshaft and no tailshaft centre-bearing fitted.
• What bearing might people confuse with a centre-bearing on a Mazda 3?
  The right‑hand intermediate shaft support (carrier) bearing in the front driveline. It supports the intermediate shaft, not a propshaft.
• What if the car is a grey‑import AWD Mazda 3?
  AWD variants from other markets can have a propshaft with a centre-bearing. Inspection involves checking the bearing mount, rubber isolator and propshaft joints for play or noise.

Popular questions about the 2023 Mazda 3 “centre-bearing”

Does my 2023 Mazda 3 have a centre-bearing?
For Australian and New Zealand models, no. They’re front‑wheel drive only, so there’s no propshaft or centre support bearing. If there’s a vibration or hum, a workshop will look instead at the front drive shafts, the right‑hand intermediate shaft support bearing, and the CVs.

What’s the difference between a centre-bearing and the intermediate shaft bearing on a Mazda 3?
A centre-bearing supports a two‑piece tailshaft on RWD/AWD cars. The Mazda 3’s intermediate shaft bearing is a small carrier bearing that supports the right‑hand drive shaft assembly on FWD cars. Different jobs, different locations, different parts.

Could an imported AWD 2023 Mazda 3 have a centre-bearing?
Yes. AWD versions from markets that offered i‑Activ AWD can use a propshaft with a centre-bearing. Maintenance is usually “inspect and replace if noisy or loose,” checking the bearing bracket, rubber isolator and propshaft joints during servicing.
