Parts for your 2007 Mazda Premacy-Centre bearing

2007 Mazda Premacy centre-bearing: what’s actually fitted

Based on technical references for the CR-series Premacy (2005–2010), a traditional tailshaft centre-bearing isn’t used on the 2007 Mazda Premacy in its common front‑wheel‑drive configuration. The Mazda CR Premacy/Mazda5 Workshop Manual and the Mazda Electronic Parts Catalogue (EPC) list front drive shafts, CV joints, and an intermediate/right‑hand driveshaft carrier bearing for FWD models, but no propeller shaft or centre support bearing. Centre support bearings are typically found on rear‑wheel‑drive or all‑wheel‑drive vehicles with a multi‑piece tailshaft. The FWD Premacy doesn’t run a tailshaft, so there’s no centre-bearing to service.

Why it’s not used on this vehicle is down to layout. The Premacy’s transaxle and differential sit up front, sending drive to two short half‑shafts. To keep torque steer in check, Mazda uses an intermediate (right‑hand) driveshaft with a support/carrier bearing mounted to the engine block/subframe, not a centre support bearing for a tailshaft. That’s consistent with FWD architecture shown in the CR Premacy workshop procedures and parts listings for AU/NZ‑market and typical JDM FWD imports.

• Centre-bearing (tailshaft support) – not applicable to FWD CR Premacy.
• Intermediate driveshaft carrier bearing – present on many FWD CR Premacy variants.

If a grey‑import 4WD variant is in play, it may use a propeller shaft with a centre support bearing, but that’s the exception. The straightforward way to verify is by checking the VIN against the Mazda EPC or inspecting for a rear differential and a longitudinal prop shaft. For the vast majority of 2007 Premacy models in Australia and New Zealand, a centre-bearing simply isn’t a thing.

What should owners look after instead? Keep an eye on the front CV boots for splits, listen for clicking on full lock (outer CVs), and feel for vibration under load that changes with throttle (often the intermediate carrier bearing or inner CVs). If there’s a dull growl at steady speeds that doesn’t change with steering input, the intermediate carrier bearing could be tired. Replacement is typically done with the right driveshaft assembly out, pressing the old bearing off the shaft and installing a quality unit with the correct circlip and bracket torque. Fresh gearbox oil seals are a smart add‑on if there’s any weep. A proper wheel alignment check and road test afterwards will round it out.

Popular questions

Does a 2007 Mazda Premacy have a centre-bearing?
Most FWD 2007 Premacy models do not. They use an intermediate driveshaft carrier bearing up front instead. Only rare 4WD variants (if present) would use a tailshaft centre support bearing.

What’s the humming or vibration at 60–90 km/h on my Premacy—could it be the centre-bearing?
On FWD Premacy models, a hum or vibration is more likely a front wheel bearing, tyre cupping, or the intermediate driveshaft carrier bearing—not a tailshaft centre-bearing.

How do I tell if my Premacy has a centre-bearing?
Look underneath: if there’s no rear diff or propeller shaft running down the centre tunnel, there’s no centre-bearing. Most AU/NZ cars won’t have one. A VIN check in the Mazda EPC will confirm drivetrain spec.
