The short version
- The 2007-2012 Mazda CX-7 uses one front number for both drivetrains. Any 2007 Mazda CX 7 wheel bearing job starts with press in ball bearing 510063.
- The rear splits by drivetrain: 512349 for front wheel drive, 512350 for all wheel drive.
- Those two rear numbers differ by exactly one digit, a common ordering mistake.
- Nothing changes across the six model years from 2007 to 2012.
One digit separates the right rear hub from the wrong one on a 2007-2012 Mazda CX-7. That single character is the whole story behind most 2007 Mazda CX 7 wheel bearing returns. Everything else on this crossover holds steady for six straight years.
The core numbers
The front is a press in ball bearing, 510063, shared by both drivetrains. There is no separate front number to worry about.
The rear is where drivetrain matters: 512349 for front wheel drive, 512350 for all wheel drive, one digit apart.

This page covers the 2007-2012 Mazda CX-7: 2007, 2008, 2009, 2010, 2011, 2012. Other years live on the main Mazda CX-7 wheel bearing page.
512349 and 512350 sit one digit apart. That is exactly why the wrong rear hub ends up on so many order forms. Front wheel drive takes 512349, all wheel drive takes 512350.
Confirm the drivetrain first. A wrong guess turns into a 2007 Mazda CX 7 wheel bearing rear hub that does not match. A typo in the last digit is the classic wrong click here.
Year by year
2007 through 2012 the CX-7 does not change its wheel bearing lineup at all. The front stays 510063 for every year and both drivetrains. The rear stays split by drivetrain, not by year.
A 2007 Mazda CX 7 wheel bearing order looks identical to a 2012 order once the drivetrain is known. Model year never enters the decision on this crossover.
Press in front, bolt on rear
The CX-7 mixes its installation styles corner to corner. The front is a press in ball bearing that seats inside the factory hub. The rear ships as a bolt on hub assembly instead.
That split matters for anyone budgeting shop time on a 2007 Mazda CX 7 wheel bearing repair. The front job simply runs longer than the rear. See press in wheel bearings for what the front side involves.
Drivetrain identification matters just as much as the press work. Confirm it before the rear hub ships, not after. Drive type and wheel bearings covers how to tell FWD from AWD.
Diagnosing a Mazda CX-7 wheel bearing
- Confirm drivetrain before ordering the rear. FWD takes 512349, AWD takes 512350, and the two numbers are one digit apart.
- Listen for a rear growl that grows with speed. A worn rear hub tends to get louder at highway speed and stay steady, unlike a tire issue.
- Check for a front hum that changes in turns. The press in front ball bearing often announces itself this way. See wheel bearing noise in turns.
- Rule out tire wear first. Cupped tires produce a similar drone to a failing hub. See tire noise or wheel bearing for the difference.
- Watch for an ABS light alongside the noise. A failing hub can trip the ABS system before it gets loud. See bad bearing and the ABS light for the pattern.
Common questions
What wheel bearing does a 2007 Mazda CX-7 use?
Every 2007 Mazda CX 7 wheel bearing job starts with front 510063. That press in ball bearing covers both drivetrains. The rear is 512349 on front wheel drive or 512350 on all wheel drive.
What wheel bearing does a 2012 CX-7 use?
The 2012 Mazda CX-7 uses the identical lineup as 2007: front 510063, rear 512349 for FWD or 512350 for AWD. Nothing changed across the run.
Why are the two rear numbers so close together?
512349 and 512350 are consecutive listings from the same catalog family, split only by drivetrain. It is a real trap at the parts counter, not a typo in the catalog itself.
Is the front bearing a full hub assembly?
No, the front, 510063, is a press in ball bearing rather than a hub assembly. It presses into the factory knuckle, not bolted on as a complete unit.
Does the front number change with all wheel drive?
No. Front number 510063 covers both front wheel drive and all wheel drive CX-7s. Only the rear splits by drivetrain.
