The short version
- The 2003 to 2008 Mazda 6 splits its front wheel bearing by design. A 2004 Mazda 6 wheel bearing is a press in ball bearing, 510053, while some 2006 to 2008 ABS cars carry a bolt on hub instead.
- The Mazdaspeed6 gets its own press in number, 510063, from 2006 to 2008.
- The rear is 512271 from 2005 to 2008. 2003 and 2004 rears are not documented in the catalogs we hold.
- On 2006 to 2008 cars, match whichever design the wheel actually shows rather than guessing from the model year alone.
Between 2003 and 2008, Mazda used two different front wheel bearing designs on this car. Sometimes both show up within the same model year. A 2004 Mazda 6 wheel bearing is a straightforward press in ball bearing, but later ABS cars are not always that simple.

This page covers the 2003-2008 Mazda 6: 2003, 2004, 2005, 2006, 2007, 2008. Other years live on the main Mazda 6 wheel bearing page.
One line documents a press in ball bearing, 510053, for 2003 through 2008. A separate line shows a bolt on hub assembly, 513350, for 2006 to 2008 four wheel ABS cars.
Pull the wheel and look at what the car actually carries before ordering. Press in work follows its own procedure on the press in wheel bearing page.
Year by year
2003 and 2004 document only the front, 510053. That covers the 2004 Mazda 6 wheel bearing job most owners search for. The rear here is an honest gap: the catalogs we hold stop short, so match the old part or run the VIN.
2005 adds the first documented rear number, 512271. The front stays at 510053 for every car without the ABS hub.
2006 through 2008 could carry either front design: the press in 510053 or the bolt on 513350 hub on ABS cars. The Mazdaspeed6 takes its own press in number, 510063, across these same three years.
One nameplate, three different bodies
This generation’s front bearing story continues on the next body. The 2009 to 2013 Mazda 6 wheel bearing page keeps the 513350 hub number in use before the 2014 to 2017 Mazda 6 wheel bearing page moves to its own numbers entirely.
None of the three Mazda 6 bodies share a full parts list. Matching the car in hand, rather than the calendar year, is the safest approach for a 2004 Mazda 6 wheel bearing job or any other year here.
Diagnosing a Mazda 6 wheel bearing
- Identify the front design first. A press in ball bearing and a bolt on hub assembly look different once the hub is off, and that decides the number before anything else.
- Confirm ABS equipment. Four wheel ABS is the signal for the bolt on hub on 2006 to 2008 cars.
- Listen for a speed related growl. See how to check a wheel bearing for the basic routine.
- Check the noise in a turn. Wheel bearing noise on turns often shifts louder toward one side.
- Rule out the tires. Compare tire noise against a bad bearing before condemning the hub.

Why does my Mazda 6 have a bolt on hub instead of a press in bearing?
