Home › Vehicles › Mazda › Mazda3 › 2014-2018 Mazda3 Wheel Bearing Part Numbers
The short version
- The 2015 Mazda 3 wheel bearing numbers split by where the car was built. Japan-built 2014-2016 cars use front hub 513354 and rear hub 512523. Mexico-built cars document only the rear, 512552.
- 2017 reuses those same rear numbers, 512523 and 512552, in the front position instead.
- The build plate inside the driver’s door is the only reliable way to tell Japan production from Mexico production.
- 2018 has no documented number. The Mexico-built front from 2014-2016 has none either; match the old part or check by VIN.
Two Mazda3 plants build this generation, and the parts list splits with them. A 2015 Mazda 3 wheel bearing order depends more on the factory, Japan or Mexico, than on the model year. That split runs through the front and the rear alike.
The core numbers
Japan-built 2014-2016 cars run front hub 513354 and rear hub 512523.
Mexico-built 2014-2016 cars document only the rear, 512552. The front there is a match or VIN job.

This page covers the 2014-2018 Mazda3: 2014, 2015, 2016, 2017, 2018. Other years live on the main Mazda3 wheel bearing page.
A 2014-2016 Mazda3 splits every number by where the car was built, Japan or Mexico. The door jamb plate is the only reliable way to tell. Nothing on the outside of the car gives it away.
2017 makes it more confusing. The front position that year takes 512523 or 512552, numbers the rear used before. Match the part already on the car rather than assuming a position from the number alone.
Year by year
2014 through 2016 split by build plant. Japan-built cars document both ends, front 513354 and rear 512523. Mexico-built cars document only the rear, 512552, so the front there is a match or VIN job.
2017 flips the pattern. The front position takes 512523 on Japan-built cars or 512552 on Mexico-built cars, numbers the rear used before. The 2017 rear itself carries no separate documented row.
2018 closes the generation with nothing documented at either end. That last model year matches the old part, same as the Mexico-built front from earlier.
Where this generation sits
The 2010-2013 Mazda3 ran a single rear number, 512347, with no build-country split at all. This car turned that into a build-plate question the earlier one never asked.
The 2004-2009 Mazda3 split its rear hub by ABS instead. Different question, same answer: check the car in front of you before ordering.
Diagnosing a Mazda3 wheel bearing
- Listen for a hum that builds with speed. A worn bearing gets louder as the car speeds up, unlike most other suspension noises.
- Check whether it changes in a turn. Weight shifting onto or off the bad bearing often makes the noise louder in one direction. See the turning-noise guide.
- Rule out the tires first. Cupped or unevenly worn tread can sound a lot like a bearing at highway speed. Compare against the tire noise page.
- Check the build plate before ordering. On this generation, the plant that built the car decides a 2015 Mazda 3 wheel bearing number more than the year does.
- Feel for play at the wheel. With the wheel off the ground, grip it at 12 and 6 and rock it. Full steps are on the wheel bearing check page.
Common questions
What wheel bearing does a 2015 Mazda3 use?
A 2015 Mazda 3 wheel bearing order depends on the build plate. Japan-built cars use front 513354 and rear 512523. Mexico-built cars document only the rear, 512552, with the front by match or VIN.
What wheel bearing does a 2017 Mazda3 use?
The front position on a 2017 Mazda3 uses 512523 for Japan-built cars or 512552 for Mexico-built cars, the same numbers used at the rear a year earlier. The 2017 rear itself has no separate documented row.
How can I tell if my Mazda3 was built in Japan or Mexico?
Check the build plate on the driver’s door jamb. It names the plant, and that plant decides every 2015 Mazda 3 wheel bearing number on this generation, front and rear alike.
Does the 2018 Mazda3 have a documented wheel bearing number?
No. 2018 closes this generation with nothing documented at either end. Match the old part or confirm the number by VIN.
Why do the 2017 front rows use the same numbers as the 2014-2016 rear?
The catalogs assign 512523 and 512552 to the 2017 front position. Those are the identical numbers used at the rear from 2014 through 2016. Match whichever part came off the car rather than assuming a position from the number alone.
