Parts for your 2014 Mazda Premacy-Centre bearing

2014 Mazda Premacy centre-bearing: what’s actually fitted

For the 2014 Mazda Premacy (CW series), a traditional propeller-shaft centre-bearing isn’t fitted or required. That style of centre support bearing is used on vehicles with a long, two‑piece driveshaft running to a rear differential (common on rear‑wheel drive or all‑wheel drive layouts). The 2014 Premacy is a front‑wheel drive MPV, so there’s no rear prop shaft and therefore no centre-bearing in the driveline.

Technical references back this up. The factory service information and parts listings for the CW Premacy show only a front transaxle with left and right driveshafts. There’s no prop shaft assembly or centre support bearing listed for this model year.

• Mazda Service Manual – Premacy/Mazda 5 (CW, 2010–2017), Driveline/Axle: details front driveshafts and an RH intermediate shaft with a support bracket, but no propeller shaft or centre support bearing.
• Mazda Electronic Parts Catalogue (EPC) – 2014 Premacy (CW): lists front driveshaft components, including an “intermediate shaft (RH) and bearing”, and does not list a centre-bearing.
• Model specifications – CW Premacy: front‑engine, front‑wheel drive only for this generation/year.

What sometimes causes confusion is the right‑hand intermediate shaft bearing. On many FWD Mazdas, including the 2014 Premacy, the longer right driveshaft is split into an inner intermediate shaft with a support bearing bolted to the engine block. Some workshops casually call that support bearing a “centre-bearing”, but it isn’t a prop shaft centre support bearing. It serves to stabilise the RH shaft, equalise shaft lengths to reduce torque steer, and keep NVH in check within the compact FWD layout.

So, if someone is chasing a “centre-bearing” for a 2014 Mazda Premacy, what they usually need is the RH intermediate shaft support bearing (or the complete intermediate shaft assembly if the bearing isn’t serviceable separately). Typical symptoms when that support bearing is worn include a droning or rumble that rises with road speed, vibration under load, or grease seepage around the bearing mount. A proper inspection on a hoist—checking for radial play, roughness when spun by hand, or noise under stethoscope—will confirm it.

Because there’s no prop shaft centre-bearing on this model, routine servicing focuses on the front driveshafts: inspect CV boots for splits, listen for bearing noise, and check that RH intermediate shaft support is tight in its bracket. Replace the intermediate shaft bearing or assembly if noisy or loose, and torque bracket fasteners to spec from the service manual.

• Does a 2014 Mazda Premacy have a centre-bearing?

No. The CW‑series Premacy is front‑wheel drive, so it doesn’t use a rear prop shaft or a prop‑shaft centre support bearing. If a shop mentions a “centre-bearing” on this car, they’re almost certainly referring to the right‑hand intermediate shaft support bearing on the front driveshaft assembly.

• I’m hearing a rumble at 60–80 km/h — could it be the centre-bearing on my Premacy?

It won’t be a prop‑shaft centre-bearing, as the vehicle doesn’t have one. However, that speed‑related rumble could be the RH intermediate shaft support bearing, a front wheel bearing, or a tyre issue. A technician can road test, then check for play and roughness at the intermediate shaft support and wheel hubs to pinpoint the source.

• What part should be ordered if the “centre-bearing” is worn on a 2014 Premacy?

Ask for the right‑hand intermediate shaft support bearing or, if specified by Mazda for your VIN, the complete RH intermediate shaft assembly that includes the bearing. Many catalogues list the bearing with the shaft as a unit, your parts supplier can confirm what’s serviceable separately for your exact engine and market spec.
