The short version
- The 2010 Mazda 3 wheel bearing setup covers the entire 2010-2013 generation on one rear number, 512347, with the front ordered by VIN or match to the old part.
- No engine or trim splits the rear hub. Every 2010-2013 Mazda3, base or otherwise, shares the same number.
- The ABS split that governed the previous generation’s rear hub is gone here.
- 512347 is not a new number. It carries straight over from the ABS-equipped cars of the 2004-2009 Mazda3.
Four model years, 2010 through 2013, and the catalogs give the rear axle exactly one part number to remember. The 2010 Mazda 3 wheel bearing chart trimmed away the ABS split that complicated the previous generation, leaving 512347 as the only rear entry. The front hub never got its own catalog row this generation, so that end still runs on VIN lookup or the old part.
The core number
One rear hub, 512347, covers every 2010-2013 Mazda3 regardless of trim or engine.
The front position has no documented number in the catalogs, so front orders match the old part or go by VIN.

This page covers the 2010-2013 Mazda3: 2010, 2011, 2012, 2013. Other years live on the main Mazda3 wheel bearing page.
The ABS versus non-ABS split that governed the 2004-2009 rear hub disappeared here. Every 2010-2013 Mazda3 rear uses 512347, the same number the ABS cars carried before.
The front hub, though, was never assigned its own row for this body. A front 2010 Mazda 3 wheel bearing order has to start from the part already on the car, not from this table.
Year by year
2010 through 2013 sit under one rear row with nothing to split it by trim, engine, or option. That single line is the entire 2010 Mazda 3 wheel bearing rear answer for all four years.
The front never gets a catalog entry across the same span. Every front order in this generation is a match-the-old-part or VIN job, from the first 2010 car to the last 2013 car off the line.
Where this generation sits
The 2004-2009 Mazda3 split its rear hub by ABS, running 512347 on the ABS cars and a separate 512348 on the rest. This generation drops that split entirely and keeps only 512347.
The following 2014-2018 Mazda3 replaces that single rear number with a split by build country, a different kind of complication.
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.
- Watch for an ABS light. A failing rear hub can disturb the wheel speed sensor built into it. The ABS light guide covers that connection.
- 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 2010 Mazda3 use?
A 2010 Mazda 3 wheel bearing job uses rear hub 512347. The front has no documented number, so match the old part or confirm by VIN.
What wheel bearing does a 2012 Mazda3 use?
The same rear hub, 512347. Nothing changes between the first and last year of this generation.
Does the front Mazda3 wheel bearing have a part number?
Not in this generation’s catalogs. Order by matching the bearing already on the car or by VIN lookup.
Is the 2010-2013 Mazda3 rear bearing the same for every trim?
Yes. 512347 covers every trim and every engine offered on this body, with no split documented anywhere.
Did the Mazda3 rear wheel bearing number change from the previous generation?
No. 512347 is the same number the ABS-equipped 2004-2009 cars used. The non-ABS 512348 number from that earlier generation does not carry forward.
