Parts for your 2013 Mazda Premacy-Wheel hubs

2013 Mazda Premacy wheel hubs — what they do and how to look after them

Wheel hubs are absolutely used on the 2013 Mazda Premacy (also known as the Mazda5). Technical sources that document this include the Mazda Premacy/Mazda5 Workshop Manual (2010–2015, Suspension and Axle sections), the Mazda Electronic Parts Catalogue (EPC), and major bearing catalogues from suppliers such as SKF and NTN-SNR, all of which list front and rear hub/bearing units for this model. So, wheel-hubs are very much relevant to the 2013 Premacy.

On this MPV, the wheel hub is the bit that the wheel bolts to. It houses the bearing that lets the wheel spin smoothly, supports the vehicle’s weight, and, in most trims, carries the ABS encoder for wheel speed sensing. Up front, the hub and bearing sit in the steering knuckle and lock to the driveshaft, at the rear, the hub is a bolt-on assembly with an integrated sealed bearing. Together, they keep the car tracking straight, keep noise down, and protect the ABS from contamination.

Because the Premacy’s hubs use sealed bearings, there’s no routine greasing. Instead, servicing is about inspection and smart replacement when wear shows up. Typical signs a hub is on the way out include a humming or growling that changes with road speed, play you can feel when rocking the wheel at the 12 and 6 o’clock positions, ABS warning lights, or uneven tyre wear. Technicians will also check for heat at the hub after a drive and look for rusty dust from a failing bearing.

When replacement is needed, go for quality hub/bearing assemblies from reputable brands. Front hubs generally require pressing the bearing in and out of the knuckle, so the right tools (and care around the ABS encoder and sensor) are crucial. The rear is usually a straightforward bolt-off, bolt-on job. Always follow the factory torque specs for the axle nut and wheel nuts (refer to the Mazda workshop manual or the vehicle’s placard), and consider a wheel alignment if the front knuckle or strut bolts were disturbed. Replacing in pairs isn’t mandatory, but if one side has failed from high kilometres or harsh use, the mate may not be far behind.

• Keep wheel nuts torqued correctly to avoid bearing stress.
• Avoid water blasting directly at the hub/ABS area.
• Rotate tyres on schedule, tyre roar can mimic hub noise.

Does the 2013 Mazda Premacy use bolt-in hub assemblies or press-in bearings?

It uses a hub and bearing unit at the front installed in the steering knuckle (with the hub splined to the driveshaft), and a bolt-on hub assembly with an integrated sealed bearing at the rear. That rear unit also incorporates the ABS encoder ring.

How long should the wheel hubs last on a Premacy?

Plenty make it well past 150,000–200,000 kilometres, but life varies with road conditions, wheel impacts (kerbs and potholes), tyre choice, and wheel-nut torque habits. If a steady humming grows with speed or the ABS light flickers without a sensor fault, it’s time to test the hubs.

Can a noisy tyre sound like a bad hub?

Yes. Chopped or cupped tyres can drone like a worn bearing. Swap tyres front to rear and recheck noise, then inspect for wheel play and use a mechanic’s stethoscope on the knuckle while spinning the wheel to confirm the diagnosis before replacing any hub.
