The short version
- 2007 Mazda3 wheel bearing numbers for the rear: 512347 with 4-wheel ABS, 512348 without it. Both hold across the full 2004-2009 run.
- 512347 and 512348 are two different hubs, not parallel listings for the same part. ABS equipment decides which one fits.
- The front carries no documented number in this generation. Order it by VIN or by matching the old bearing.
- No year inside 2004-2009 changes either rear number. ABS equipment is the only question that matters.
The 2004-2009 Mazda3 keeps its rear wheel bearing choice down to one question for the entire run. A 2007 Mazda3 wheel bearing order still comes down to that same ABS check.
The core numbers
Every 2004-2009 Mazda3 with 4-wheel ABS takes rear hub 512347. Cars without ABS take 512348, a different hub rather than an alternate listing.
The front has no documented number this generation. Order by VIN or match the part already on the car.

This page covers the 2004-2009 Mazda3: 2004, 2005, 2006, 2007, 2008, 2009. Other years live on the main Mazda3 wheel bearing page.
512347 and 512348 look like they could be parallel listings for the same rear hub, but they are not. They are two different parts, split strictly by whether the car carries 4-wheel ABS.
A 2007 Mazda3 wheel bearing order that ignores ABS equipment risks the wrong hub entirely. Check the brakes before ordering either one.
Year by year
2004 through 2009 share one answer at the rear: 512347 with 4-wheel ABS, 512348 without it. Nothing changes at any point in the run.
A 2007 Mazda3 wheel bearing order follows the exact same ABS check as a 2005 or a 2009. The front never gets a catalog row across this whole generation.
Where this body sits in the Mazda3 line
This Mazda3 body runs 2004 through 2009 before the next body arrives. The 2010-2013 Mazda3 generation simplifies the rear to a single number, dropping the ABS split entirely.
Inside this generation, the ABS check is the whole story at the rear. The front stays a VIN job no matter the year.
Diagnosing a Mazda3 wheel bearing
- Listen for speed-related noise. A worn rear bearing typically hums and shifts pitch in a turn. That pattern is covered in how wheel bearing noise changes while turning.
- Rule out the tires. Uneven wear can sound close to a bad bearing at highway speed. Check tire noise versus wheel bearing noise before ordering.
- Check for hub play. With the wheel raised, rock it top and bottom. Looseness there points to the bearing rather than the tire.
- Watch the ABS light. A failing rear hub on an ABS car can trip a fault. A bad bearing setting off the ABS light is a known pattern on this platform.
- Confirm ABS equipment first. Check the brakes for a 4-wheel ABS system before choosing between 512347 and 512348.
