Parts for your 2025 Mazda 3-Centre bearing

2025 Mazda 3 centre-bearing: what it is, and why this Mazda doesn’t use one

After checking factory documentation and parts catalogues, it’s clear the 2025 Mazda 3 sold in Australia and New Zealand does not use a centre-bearing (also called a centre support bearing). That’s because the local BP-series Mazda 3 is a front‑wheel drive hatch or sedan with a transverse engine, so there’s no long, multi‑piece propeller shaft running to the rear that would need a centre-bearing.

Technical sources referenced:

• Mazda Australia Mazda 3 (BP) 2025 specifications and brochure – lists front‑wheel drive only for local models.
• Mazda Workshop Manual (BP platform) – Driveline/Axle sections cover front driveshafts and hubs, no propeller shaft or centre support bearing procedures for FWD variants.
• Mazda Electronic Parts Catalogue (BP chassis) – for AU/NZ FWD models, shows left/right front driveshafts only, no “propeller shaft” or “centre support bearing” part listings.

Why there’s no centre-bearing on a 2025 Mazda 3: centre-bearings are used to support long, two‑piece propeller shafts typically found in rear‑wheel drive utes and SUVs, or some AWD setups. The BP‑series Mazda 3 in Australia and New Zealand sends power straight to the front wheels via short left and right driveshafts. With no rear differential to feed and no long shaft under the floor, there’s simply nothing that needs a centre support. The rear of the Mazda 3 uses a compact torsion beam suspension, which also leaves no room or requirement for a prop shaft on these FWD cars.

Worth noting: in some overseas markets there are AWD Mazda 3 variants. Those cars add a propeller shaft to the rear differential, and depending on design, may use a centre-bearing. That configuration isn’t offered locally, so Australian and New Zealand owners won’t have a centre-bearing to service or replace on a 2025 Mazda 3.

FAQs

Does a 2025 Mazda 3 have a centre-bearing?
No. The 2025 Mazda 3 sold in Australia and New Zealand is front‑wheel drive and doesn’t have a propeller shaft, so it doesn’t use a centre-bearing. Routine driveline servicing focuses on front driveshaft CV boots/joints, transmission fluid (as specified), and wheel bearings.

Why don’t front‑wheel drive cars like the Mazda 3 use a centre-bearing?
A centre-bearing supports a long, two‑piece prop shaft that runs to a rear differential. FWD cars transmit power to the front wheels with short driveshafts, so there’s no long shaft to support. That’s why a centre-bearing isn’t part of the Mazda 3’s layout.

If I import an AWD Mazda 3, will it have a centre-bearing?
Some AWD Mazda 3 models in other markets use a propeller shaft to the rear, and may employ a centre-bearing depending on the exact design. Anyone considering an import should check the VIN in the Mazda EPC or the workshop manual for that specific AWD variant to confirm parts and service requirements.
