Home › Vehicles › Acura › Acura TLX Wheel Bearing Part Numbers
The short version
- The Acura TLX wheel bearing at the rear splits by drivetrain, 512544 for FWD and 512562 for SH-AWD, covering 2015 to 2019.
- 2020 rear hubs and every front hub across the generation are not documented, match by VIN or the old part.
- SH-AWD cars need the different rear number, not the FWD one, so confirming drivetrain matters before ordering.
- The TLX replaced both the TL and the TSX in Acura’s lineup starting with the 2015 model year.
Acura folded two sedans, the TL and the TSX, into one nameplate when the TLX launched for 2015. The parts catalogs kept the hub numbers split anyway, dividing the rear by drivetrain rather than treating it as one row.
Rear hubs split by drivetrain, not by trim
512544 covers FWD cars from 2015 to 2019, while 512562 covers SH-AWD cars over the same span.
Front hubs are not documented for any year of the generation, so those go by VIN or by matching the old part.

Every model year this chart resolves: 2015, 2016, 2017, 2018 and 2019. On this chart a 2020 Acura TLX is not documented, so those cars go by the old part or the VIN.

Lookups run through the cross reference page.
512544 and 512562 are not interchangeable. The catalogs list the SH-AWD rear as its own part, not a substitute for the FWD number.
Check the drivetrain badge or the door jamb sticker before paying, since both boxes look similar on a shelf.
Kin from two different Acura eras
The TLX does not have a single predecessor page here, since it absorbed both the TL and the TSX. The closest kin on this site are the TSX page and the MDX page, each carrying its own numbers rather than the TLX’s.
The TLX also shares platform roots with Honda’s own sedan, covered on the Accord page. Platform kinship is not the same as a shared bearing number, so none of these pages substitute for the TLX’s own rows.
SH-AWD adds load, not just hardware
SH-AWD sends torque to the rear axle in a way FWD never does, and the rear-specific 512562 number reflects that extra duty. A rear bearing on an SH-AWD car works harder over the same mileage than the FWD equivalent.
Diagnosing an Acura TLX wheel bearing
- Identify FWD or SH-AWD before ordering any rear hub.
- Check the model year against the 2020 gap in the rear chart.
- Match the old front hub directly, since no front number is documented.
- Rock each wheel to feel for vertical play at the hub.
- Cross check the retail listing against the VIN before paying.
The full process is on the wheel bearing check page, and how drivetrain changes the rear hardware is explained on the drive type and bearings page.
Common questions
Which Acura TLX wheel bearing fits the rear?
512544 for FWD, 512562 for SH-AWD, both covering 2015 to 2019. Confirm the drivetrain before ordering either one.
What about the front hub?
No front number is documented for the TLX. Match the old part or order by VIN.
Does 2020 use the same rear number?
It is not documented in this run of numbers. Treat 2020 the same as the front hubs, match the old part or the VIN.
Can an FWD rear hub fit an SH-AWD TLX?
No. The two numbers are separate for a reason, and swapping them is not a documented fit.
Is the TLX related to the TL or TSX for parts purposes?
It replaced both nameplates, but the rear numbers documented here are the TLX’s own. The TSX and MDX pages are useful for cross-shopping, not for substituting parts.
