Parts for your 2000 Mazda Premacy-Wheel hubs

2000 Mazda Premacy wheel hubs — what they do and how to look after them

Technical sources confirm wheel hubs are absolutely relevant and fitted to the 2000 Mazda Premacy. The Mazda Premacy (CP platform) Workshop Manual (1999–2001, Suspension/Driveline sections), the Mazda Electronic Parts Catalogue (EPC), and aftermarket catalogues from bearing specialists like SKF and NTN all list front and rear hub and bearing assemblies for this model. The front uses a press-in double-row bearing with a separate hub, while the rear uses a hub-and-bearing unit suited to the vehicle’s drum or disc rear brake setup, often with an integrated ABS tone ring.

On this Premacy, the wheel hub is the central mounting point that locates the wheel, houses the wheel bearing, and provides the interface for the brake rotor or drum. It keeps the wheel rotating smoothly on the axle or knuckle and maintains correct alignment under load. Where ABS is fitted, the hub or bearing typically carries the tone ring that the sensor reads for wheel speed.

Because the bearings are sealed, they’re not a grease-and-go item, maintenance is about inspection and correct fitment. During routine servicing, it’s wise to check for play by rocking the wheel at 12 and 6 o’clock, listen for humming or growling that rises with road speed, and scan for ABS faults. Any roughness when spinning the wheel by hand with the brake pads backed off points to a tired bearing.

Replacement on the front is a press job and benefits from the right tools. The knuckle needs supporting so the new bearing isn’t side-loaded, and the hub must be pressed squarely into the inner race. A new axle nut should be used and torqued to Mazda spec, over- or under-tightening can kill a fresh bearing quickly. Rear hub units are more straightforward: they’re removed from the stub axle or carrier, then refitted with a new nut or lock feature, and the park-brake is adjusted as needed. After any hub work, a road test and a quick wheel alignment check are smart moves, especially if the knuckle has been out.

• Keep the hub face clean and free of rust before refitting the wheel.
• Torque wheel nuts correctly, avoid rattle-gun overkill.
• Inspect ABS sensors and wiring whenever a hub is off the car.

Popular questions about 2000 Mazda Premacy wheel hubs

How can someone tell if a Premacy wheel hub or bearing is failing?
Typical signs include a droning or humming that increases with speed, a change in tone when turning, play felt when rocking the wheel, uneven tyre wear, or the hub running noticeably hot after a drive. On ABS-equipped cars, a failing hub or tone ring can also trigger the ABS warning light.

If noise changes when loading one side (for example, turning right makes the left-front noisier), that often points to the opposite side hub. Always confirm by spinning the wheel off the ground and feeling for roughness.

Are the rear hubs the same on drum and disc brake versions?
No. Technical listings in Mazda’s EPC and bearing catalogues show different rear hub assemblies depending on whether the vehicle has rear drums or discs, and whether ABS is fitted. The mounting style and the presence of an integrated tone ring vary.

When ordering, match by VIN, brake type, and ABS. Mixing styles can cause fit or ABS issues.

Can a DIYer replace the front wheel bearing at home?
It’s possible but not always practical without a quality press, proper drifts, and a torque wrench. The front bearing is a press-fit into the knuckle, and incorrect support or pressing on the wrong race can ruin a new bearing or distort the knuckle.

Many owners opt to remove the knuckle and have a workshop press the bearing and hub, then refit it at home with new hardware torqued to spec.
