The short version
- A Mazda6 wheel bearing follows the generation cleanly, and the 2003 to 2004 cars now resolve alongside the rest below.
- The 2003 to 2004 front used a press in ball bearing, 510053, a different design from the bolt on hub used from 2005 on.
- 513347 is cited for the 2014 onward front and 512519 for the rear of the same cars.
- Earlier cars run 513350 at the front, with 512409 and then 512271 at the rear going back.
The Mazda3 is one of the strangest ordering jobs on this site. Its larger sibling is one of the tidiest, and the contrast is worth stating.
A Mazda6 wheel bearing changes at clean generation boundaries across 2003 to 2016, with no trim or build country trap hiding in the middle.
Generation decides it
513347 is cited for the 2014 to 2017 front and 512519 for the rear of the same cars.
Earlier cars run 513350 at the front, with 512409 and then 512271 at the rear going back.
The earliest cars, 2003 to 2004, used a different design entirely at the front, a serviceable press in ball bearing rather than the bolt on cartridge hub every later Mazda6 uses.
The rear for those years also splits by drivetrain and by ABS, front wheel drive with ABS, front wheel drive without it, and all wheel drive as a third listing.
The year answers the question here. A car near a generation cutoff is the only case needing a second look.

Every model year this chart resolves: 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 and 2016.
The Mazda3 splits on where the car was built, Japan or Mexico, and nothing outside the car reveals which.
Nothing equivalent applies here. The Mazda6 splits cleanly by generation and, only in the earliest cars, by drivetrain and ABS.
Why the Mazda3 is harder
That build country split is worth knowing if you own both cars, since a Mazda6 owner reading the Mazda3 page could otherwise expect the same trap.
One catalog carries all four 2003 to 2004 numbers alone. Two others have no Mazda6 listings at all in this file, so match the old part carefully on those years rather than assuming a second catalog will confirm it.
The site position on pairs
Parts listings for these often specify a quantity of two, which reads as an instruction to replace both sides.
It is not. That is a packaging convention. Replace what is worn and leave a good bearing alone.
Doing the job
Bolt on hubs at both ends from 2005 on mean no press, and the labor stays modest. The 2003 to 2004 front is the exception, since that press in design is covered generally on the press in page.
Torque the axle nut to spec afterward, because that nut sets the preload on a fresh unit.
Diagnosing a Mazda6 wheel bearing
- Note the generation, since that is what decides the part.
- Coast in neutral at the noise speed.
- Weave at road speed and note the loaded direction.
- Rock the wheel at twelve and six.
- Rule out the tires before buying a hub.
Those are on the checking page and the tire noise page.

Common questions
Which Mazda6 wheel bearing do I need?
The year answers it. 513347 for the 2014 onward front, 513350 for the middle years, and 510053 for 2003 to 2004.
Is there a build country split like the Mazda3?
Not on this car. The Mazda3 trap does not carry across.
The listing says quantity two. Do I need both?
No. That is a packaging convention, not a diagnosis.
Do I need a press?
Only for the 2003 to 2004 front. Every other position on this car bolts on.
What ruins a new one fastest?
An axle nut that was never torqued properly.
