The short version
- The CX-3 wheel bearing story up front is borrowed: the 513354 hub shared with the 2014 to 2018 Mazda3.
- The rear runs the 512661 family, with a separate 512660 listing tied to all wheel drive.
- Coverage is the 2016 to 2021 US run, retail verified.
- Mazda’s own rear number is D10E-26-15X.
Mazda built its smallest crossover on the Mazda2’s bones with Mazda3 parts sprinkled through, and the bearings follow that recipe: a shared front, and a rear that asks about the driven wheels.
The borrowed front
The front CX-3 wheel bearing is the 513354 bolt-on hub, retail listed for 2016 to 2021 and for the 2014 to 2018 Mazda3.
The sedan’s volume keeps this crossover’s front cheap.

The rear drivetrain check
Retail listings separate the CX-3’s rears by drivetrain, and Mazda’s own D10E-26-15X sits behind them.
Check for the rear driveshaft or run the VIN before ordering the back.
The Mazda family
The bigger crossovers run their own charts on the CX-5 page, and the donor sedan’s story is on the Mazda3 page. The make overview is on the Mazda page.
Small car, city miles
CX-3s live on urban commutes where potholes do the real damage, per the pothole page. Otherwise the light body is gentle on bearings and they last well past 100,000 miles.
Diagnosing a CX-3 wheel bearing
- Confirm the drivetrain before a rear order.
- Weave at speed and place the hum.
- Rule out tire drone, loud in a light car.
- Rock each wheel at twelve and six.
- Cross-shop Mazda3 listings for the front.
The routine is on the checking page and the tire noise page.
