Parts for your 2013 Mazda Premacy-Wheel bearings

2013 Mazda Premacy wheel bearings: what they do and when to replace them

Wheel bearings are absolutely fitted to the 2013 Mazda Premacy. Mazda’s workshop manual for the Premacy/MAZDA5 (2010–2015) cites unitised front and rear wheel hub bearings in the Front and Rear Axle sections, and the Mazda Electronic Parts Catalogue lists complete hub-and-bearing assemblies for both axles. Major bearing manufacturers’ catalogues (SKF, NTN/SNR, Timken) also specify direct-replacement hub units for this model and year. Put simply, this vehicle relies on sealed, double-row hub bearings to support the wheels, manage cornering loads, and keep things rolling smoothly and quietly.

On this Premacy, each hub bearing carries the car’s weight, keeps rolling resistance low, and provides a precise path for the ABS tone ring to deliver clean wheel-speed signals. Because the bearings are sealed and preloaded at the factory, there’s no routine greasing or adjustment. When healthy, they’re quiet, tight, and help the tyres wear evenly, when tired, they hum, growl, or allow the wheel to wobble over bumps.

Servicing focuses on inspection rather than periodic replacement. During regular maintenance, a tech will road test for a low-pitch hum that rises with speed, spin each wheel off the ground and feel for roughness, and check for play with hands at 12 and 6 o’clock. They’ll also look for ABS faults that can stem from a damaged encoder ring inside the hub. Keeping wheel torque correct, avoiding water blasting directly at the hub, and nipping any CV boot or brake shield issues early all help bearings live a long life in Australasian conditions.

• Drumming or growling noise that changes with speed or load
• Play at the wheel rim or vague steering feel
• ABS light triggered by erratic wheel-speed signals
• Uneven tyre wear despite correct alignment
• Heat or discolouration at the hub after a drive

When a bearing is noisy or loose, replacement is the fix, it’s not a serviceable part. The Premacy typically uses a bolt-in hub assembly (front and rear), so the job involves removing the brake hardware, unclipping the ABS lead, and swapping the hub. Correct axle-nut torque is critical—over- or under-torque can shorten the new bearing’s life. Quality OEM-equivalent hubs and a proper alignment check afterwards will keep this Mazda quiet and sure-footed for many more kilometres.

Popular questions about 2013 Mazda Premacy wheel bearings

How can someone tell which wheel bearing is failing on a 2013 Premacy?

A road test that loads the car side to side helps: a right-hand sweep that quietens the noise often points to the right bearing (and vice versa). Spinning each wheel off the ground and feeling for roughness or play is the next step. A mechanic may use a mechanic’s stethoscope or chassis ears on the knuckle to pinpoint the culprit.

Do the Premacy’s bearings get repacked, or are they complete hubs?

They’re sealed, unitised hub bearings—no repacking, no adjustment. Once worn or noisy, the whole hub assembly is replaced. This design keeps contaminants out and alignment spot-on, but it does mean replacement rather than overhaul when they fail.

How long do wheel bearings last on this model?

There’s no fixed interval. Many last well beyond 120,000–200,000 km, but rough roads, water ingress, curb strikes, or incorrect wheel/axle nut torque can shorten life. Regular inspections and proper torque practices during brake or suspension work make a big difference.
