The short version
- The 2013 Kia Optima wheel bearing rear hub is 512437, covering all five years, 2011 through 2015.
- The front, the most-searched bearing on this car, is not documented in the catalogs we hold.
- Match the number the old front part carries, or run the VIN, rather than guessing.
- The rear number is shared with the Sonata of the same era.
Five model years, 2011 through 2015, share one rear hub and a front gap that draws more searches than any other row on this page. The 2013 Kia Optima wheel bearing rear number is settled: 512437 covers the whole run. The front simply is not in the catalogs we hold.
One rear number, an honest front gap
Moog lists 512437 for the Optima rear hub. It is shared with the Sonata of the same era.
The front has no documented number for 2011-2015. Match the number the old part carries, or run the VIN.

The front is the most-searched wheel bearing on this car, and it is exactly the one the catalogs skip. No listed number exists, and a guessed one is worse than none.
Match the number the old front part carries, or run the VIN, every time.
Year by year
One rear number, 512437, covers all five years, 2011 through 2015, with no changes. The front stays a gap the whole run on the 2013 Kia Optima wheel bearing chart, and the catalogs we hold never fill it in.
This Optima and the one before it
This body follows the 2007-2010 Optima wheel bearing page, where the front bearing is still a documented press-in part. Here that front listing disappears from the catalogs entirely.
The next redesign begins the 2016-2020 Optima wheel bearing page, where the front returns with its own number.
Diagnosing an Optima wheel bearing
- Listen for the pattern. A worn wheel bearing hums or growls, and the pitch tracks with road speed, not engine RPM. See wheel bearing noise on turns for what changes in a corner.
- Rule out the tires first. Cupped or unevenly worn tires can mimic a bearing hum. Compare against tire noise versus wheel bearing noise before pulling anything apart.
- Check for play. With the wheel off the ground, grab it at 12 and 6 o’clock and rock it. Looseness at the hub points to the bearing, covered in how to check a wheel bearing.
- Watch the ABS light. A failing hub can drag down the ABS sensor signal at either end. A bad bearing and the ABS light covers the connection.
- Pull the old front hub before ordering. Since the front is not in the catalogs we hold, read the number off the old part or run the VIN through a parts counter.
Common questions
What wheel bearing does a 2013 Kia Optima use?
A 2013 Kia Optima wheel bearing rear hub is 512437. The front is not documented in the catalogs we hold; match the number the old part carries or run the VIN.
What wheel bearing does a 2015 Kia Optima use?
The same rear hub, 512437, applies to a 2015 Optima. The front gap is the same as every year in this generation.
Why isn’t there a 2013 Kia Optima front wheel bearing number listed?
The catalogs we hold simply stop short of a front listing for this 2013 Kia Optima wheel bearing generation. That is the single most-searched question on this page, and the honest answer is a gap, not a guess.
Does the Optima share its rear hub with another model?
Yes. Rear hub 512437 is the same listing used on the Sonata of the same era.
How do I find the correct front wheel bearing without a catalog listing?
Pull the old hub and read the number stamped on it, or take the VIN to a parts counter that can run it. Both beat guessing between unrelated listings.
