This page covers the 2007-2015 Mazda CX 9: 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015. Other years live on the main Mazda CX 9 wheel bearing page.
The front bearing is a press-in cartridge design, so budget for a press rather than a bolt-on swap. One catalog documents this bearing with the CX-7 for 2007-2009, and the site’s own table carries the same number through 2015.
The AWD rear listing runs a year past this body in one catalog, to 2016. Match the number the old part carries rather than trusting either end date.
Year by year
A 2010 Mazda CX 9 wheel bearing job looks the same as one from 2007 or 2015. One front bearing and one rear pair cover the whole nine year run, with no changes by model year.
The only real split is drivetrain at the rear: 512452 for front wheel drive, 512449 for AWD.
What the press-in design means for this job
A 2010 Mazda CX 9 wheel bearing at the front is not a bolt-on part. Read press-in wheel bearing replacement before planning the job.
The rear hub assemblies use a more conventional bolt-on design. Drivetrain confirmation matters more there than press equipment does.
Diagnosing a Mazda CX 9 wheel bearing
- Listen for a hum that builds with speed. A failing bearing grows louder as road speed increases; read how to check a wheel bearing to compare symptoms.
- Jack up the noisy corner. Grip the tire at 12 and 6 o’clock and rock it to feel for play at the hub.
- Confirm the drivetrain before ordering a rear hub. Front wheel drive and AWD CX 9s take different rear numbers.
- Plan for a press on a front job. The front bearing is a press-in cartridge, not a bolt-on hub assembly.
- Check the ABS light. A worn bearing can damage its sensor and trigger a bad bearing ABS light.

Is the front bearing the same on a 2007 CX 9 as a 2015 one?

Is the CX 9 front wheel bearing press-in or bolt-on?
