The short version
- The 2018 Kia Optima wheel bearing numbers are front hub 513374 and rear hub 512553, both documented 2016-2019.
- The 2016 front listing names trims: EX, LX, SX-T GDI, and SXL.
- 2020 front and rear are not documented; match the old part or run the VIN.
- The same two numbers also serve the Sonata and Tucson of this era.
Five model years, 2016 through 2020, ride on two numbers with a trim qualifier and a final-year gap. The 2018 Kia Optima wheel bearing front hub is 513374, and the rear hub is 512553. Both cover 2016 through 2019, with 2020 left undocumented.
Two numbers, one trim qualifier, one gap year
Moog names specific trims for the 2016 front listing: EX, LX, SX-T GDI, and SXL. Later years carry the same number without the trim breakdown.
2020 front and rear are not documented in the catalogs we hold. Match the number the old part carries, or run the VIN.

This page covers the 2016-2020 Kia Optima: 2016, 2017, 2018, 2019, 2020. Other years live on the main Optima wheel bearing page.
The 2016 front listing names trims, EX, LX, SX-T GDI, and SXL, while later years drop that qualifier. The rear spans also disagree across listings between 2016-2017 and 2017-2019.
513374 and 512553 also serve the Sonata and Tucson of this era. Confirm model and year, and match the old part on a 2019-2020 car.
Year by year
2016 carries the front hub as 513374 with trim call-outs, and the rear as 512553 under one listing. 2017 through 2019 keep both numbers, with the rear spans overlapping between two separate listings.
2020 is a gap at both ends on the 2018 Kia Optima wheel bearing chart. Match the number the old part carries, or run the VIN, rather than assuming the prior year’s numbers still apply.
This Optima and the one before it
This body follows the 2011-2015 Optima wheel bearing page, where the front is a documented gap rather than a listed number. Here the front finally returns with 513374.
The same two numbers, 513374 and 512553, also serve the Sonata and Tucson of this era. Confirm the model before ordering from a lookup that lists more than one vehicle.
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.
- Confirm trim and year on a 2016 car. Since the front listing names specific trims, check the door jamb sticker against EX, LX, SX-T GDI, or SXL before ordering.
