Parts for your 1999 Mazda Premacy-Centre bearing

1999 Mazda Premacy centre bearing — do you actually have one?

For Australia and New Zealand–spec 1999 Mazda Premacy (CP series, front‑wheel drive), a centre bearing isn’t fitted and isn’t relevant. That’s because these cars run a transverse transaxle with two short CV half‑shafts and no tailshaft/prop shaft to the rear. A centre (centre support) bearing is only used on two‑piece prop shafts, which you’ll find on rear‑wheel drive or some all‑wheel drive layouts.

This isn’t just workshop folklore. The Mazda Premacy CP Workshop Manual and service schematics for the FWD models show no propeller shaft group and no centre support bearing, they focus on CV joints, wheel bearings, and (on some engines) a right‑hand driveshaft carrier bearing on the intermediate shaft. The Mazda electronic parts catalogue (CP Premacy) likewise lists no centre support bearing for FWD models, while a prop shaft and support appear only on certain 4WD CP8W variants sold in Japan. Most AU/NZ‑delivered Premacy vehicles are FWD, so a centre bearing doesn’t enter the picture.

Why it isn’t used on the local 1999 Premacy:

• FWD layout: torque goes straight from the transaxle to the front wheels via CV shafts—no long tailshaft to support.
• No two‑piece shaft: a centre bearing’s whole job is to support a long, two‑piece prop shaft in the middle of the car.
• Different “support” part: some FWD Premacy variants have a right‑hand intermediate driveshaft with a small carrier bearing on a bracket. That’s not the same thing as a tailshaft centre bearing, and it’s serviced differently.

A quick way to double‑check your car’s setup:

1. Look underneath: if there’s no long shaft running down the centre tunnel to a rear diff, there’s no centre bearing to worry about.
2. Check the model code/VIN details: AU/NZ cars are typically FWD, rare JDM 4WD imports (CP8W) can have a two‑piece prop shaft with a centre support.
3. Noise diagnosis: humming or vibration on FWD Premacy is more likely tyres, a wheel bearing, a CV joint, or that right‑hand driveshaft carrier bearing—rather than a non‑existent centre bearing.

Popular questions

Does a 1999 Mazda Premacy have a centre bearing?
For AU/NZ‑delivered FWD models, no. There’s no prop shaft, so no centre support bearing. If the vehicle is a grey‑import 4WD variant (CP8W), it may use a two‑piece prop shaft with a centre bearing.

How can I tell if my Premacy is the 4WD version that uses a centre bearing?
Look underneath for a prop shaft running to a rear differential. You’ll also see a rear diff and driveshafts to the rear wheels. The build plate/model code and import paperwork can confirm CP8W 4WD spec. If you only see front CV shafts and no rear diff, it’s FWD and has no centre bearing.

I’m getting a droning noise—could it be the centre bearing on my FWD Premacy?
Unlikely. On FWD Premacy, common causes are tyre roar, a front wheel bearing, a worn CV joint, or (if equipped) the right‑hand driveshaft carrier bearing. A road test and under‑car inspection will pinpoint the source far better than swapping parts at random.
