The short version
- The front CX-7 wheel bearing is 510063, press-in, identical to the CX-9’s.
- The rears are this car’s own and split by drivetrain: 512349 front wheel drive, 512350 all wheel drive.
- Do not buy a CX-9 rear hub for this car. Same front, different backsides.
- Catalogs verify 2007 to 2009 directly; the same numbers are listed at retail through 2012.
The CX-7 and CX-9 came out of the same Mazda studio in the same era and share their front bearings exactly. Which makes it dangerously easy to assume the rears match too. They do not.
Same front, different rear
Both crossovers press 510063 into their front knuckles, so front listings for either vehicle serve both.
At the rear the CX-7 uses 512349 or 512350, while the bigger car uses entirely different hubs. A CX-9 rear will not bolt to this vehicle.
The three-row sibling has its own page, including its famous appetite for bearings.

Front wheel drive or all wheel drive
Turbo CX-7s came both ways, and the naturally aspirated late cars were front drive. The rear hubs differ between them.
Look under the car for a rear differential, or run the VIN. Guessing from the trim name is unreliable on this model.
The front is press work
Like its big sibling, the CX-7 uses a press-in front ball bearing rather than a bolt-on hub. Budget for pulling the knuckle and pressing, or for the two-step approach of paying a shop just for the press time.
That method is on the press-in bearing page, with shop pricing on the press service page.
The turbo adds heat, not part numbers
The 2.3 turbo cars run hard and hot, but the bearing listings do not split by engine. Where the turbo matters is diagnosis, since a tired turbo drone and a bearing hum can blur together at cruise. Load the chassis with a gentle weave to separate them, since only the bearing changes with cornering weight.
Diagnosing a CX-7 wheel bearing
- Confirm the drivetrain before ordering a rear hub.
- Weave at highway speed to separate bearing hum from driveline noise.
- Rock each wheel at twelve and six.
- Check the front bearings during brake work, since the knuckle is already half stripped.
- Buy by number, not by which Mazda crossover a listing names.
The full method is on the checking page.
Common questions
Which CX-7 wheel bearing fits the rear?
512349 for front wheel drive, 512350 for all wheel drive. Confirm which car you have first.
Is the front shared with the CX-9?
Yes, both use 510063. It is the rears that differ between the two.
Does the turbo engine change the parts?
No. The listings do not split by engine, only by drivetrain at the rear.
Do I need a press?
For the front, yes. The rear is a bolt-on hub assembly.
Do these fail as often as CX-9 bearings?
The CX-7 does not carry the same notorious reputation. It is a lighter vehicle on the same basic hardware, which works in its favor.
What about 2010 to 2012 cars?
Retail listings apply the same three numbers to the end of production. Confirm against your own vehicle as always.
