The short version
- The Acura RDX wheel bearing at the rear carries three different numbers depending on generation and drivetrain.
- 512345 covers every gen1 rear from 2007 to 2012, before the RDX moved to a second generation in 2013.
- Gen2 rear hubs split further, 512448 for FWD through 2018, 512501 for AWD but only through 2015.
- A 2016 to 2018 AWD rear is not documented, and neither is any front hub. Match by VIN or the old part.
Acura turbocharged the first generation RDX, an unusual choice for the segment at the time. The wheel bearing chart spreads three different numbers across two generations. It takes more care to read than the engine bay does.
Three numbers, two generations
512345 is the gen1 number, unchanged from 2007 to 2012 regardless of drivetrain.
Gen2 splits by drivetrain, 512448 for FWD through 2018, and 512501 for AWD, but only through 2015.

Lookups run through the cross reference page.
512501 is only documented through 2015, even though gen2 AWD RDXs sold all the way through 2018.
A 2016 to 2018 AWD rear is not covered by that number. Match the old part or confirm by VIN instead of assuming continuity.
Shared roots with the CR-V, split by SUV duty
The first generation RDX rode on a stretched version of the CR-V platform, covered on the CR-V page. The turbocharged engine and heavier trim were RDX-specific from the start.
Acura’s larger crossover, the MDX page, runs its own separate numbers. It is worth checking only for cross-shop context, not substitution. For the wider lineup, the Acura page covers each model’s own chart.
AWD adds load the FWD rear never sees
An AWD RDX routes power through the rear axle constantly. That is likely why Acura split the rear number by drivetrain starting in gen2. The FWD rear carries less duty and gets the longer-running number, 512448, through the end of the generation.
Diagnosing an Acura RDX wheel bearing
- Identify the generation, 2007 to 2012 or 2013 to 2018, before pulling a number.
- Confirm FWD or AWD on gen2 cars before ordering the rear.
- Check the model year against the 2015 cutoff on the AWD rear number.
- 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. How AWD changes the hardware is explained on the drive type and bearings page.
Common questions
Which Acura RDX wheel bearing fits the rear?
It depends on generation and drivetrain. 512345 covers 2007 to 2012 rears. 512448 covers gen2 FWD through 2018, and 512501 covers gen2 AWD through 2015 only.
What covers a 2016 to 2018 AWD rear?
Nothing documented in this run of numbers. Match the old part or confirm the number by VIN.
Is there a documented front number?
No. Front hubs are not documented for either generation, so match the old part or order by VIN.
Does the FWD rear number change across gen2?
No. 512448 covers FWD rears for the entire 2013 to 2018 run, unlike the AWD number which stops at 2015.
Was the first generation RDX turbocharged?
Yes. Acura used a turbocharged four cylinder in the 2007 to 2012 RDX, unusual for the segment then. It has no bearing on which hub number applies.
