The short version
- Front RSX wheel bearing units for 2002-2006 are press-in ball bearings, part 510039.
- That front number is the same one the 1997-2001 Honda Prelude used.
- The rear hub bolts on and carries a single number, HA590005, across the whole run.
- The Type S follows the same RSX wheel bearing chart as every other trim.
Acura replaced the Integra with the RSX in 2002, and the front end kept a family trait. The press-in ball bearing up front traces its number to a Honda Prelude built years earlier. That kind of parts sharing is common across this platform family.
RSX wheel bearing numbers at a glance
Every 2002-2006 RSX uses front number 510039, a press-in ball bearing that seats in the knuckle.
The rear hub, HA590005, bolts on and covers the same span with no year or trim split.

Unlike the Integra it replaced, the RSX rear hub does not split by ABS or trim. HA590005 covers the entire 2002-2006 run.
The front number also traces to a Honda Prelude, but a later one than the Integra used, so do not cross-order between the two model families.
The Integra’s successor, with a Prelude twist
The Acura Integra came first, and the RSX picked up where it left off. Both cars leaned on Honda’s parts bin for the front bearing, though each generation used a different Prelude era. The RSX wheel bearing chart reflects the later Prelude, not the one the Integra used.
The RSX shared its platform roots with other Acura models of the period and, more distantly, the Honda Civic. That shared engineering base is why cross reference tools flag Honda numbers next to Acura part numbers so often.
Press work forward, a bolt-on job in back
Replacing the front RSX wheel bearing means pressing it out of the knuckle. Most owners take that job to a shop with the right press. The rear is far simpler, needing only a socket set to unbolt the hub.
That labor gap is worth factoring into any repair quote. A press job costs more in shop time than a bolt-on hub swap.
Diagnosing an RSX wheel bearing
- Listen for speed-related hum. A failing RSX wheel bearing produces a hum or growl that rises with road speed rather than engine RPM.
- Note whether turning changes the sound. Load shifts during a turn often make bearing noise louder on one side, as described in this guide to turning noise.
- Compare against tire wear. Cupped tires can sound similar to a bad bearing, so check tire noise versus bearing noise first.
- Check for play at the wheel. With the wheel raised off the ground, rock it top and bottom following this check procedure.
- Inspect the hub for ABS sensor faults. A worn hub can disrupt the ABS signal, since the hub assembly and ABS sensor share the same housing.
Common questions
Does the Type S use a different bearing?
No. The Type S follows the same RSX wheel bearing chart as the base model, with no separate part numbers.
Can the rear hub be replaced without special tools?
Yes. It is a bolt-on hub assembly, so a socket set and a torque wrench cover the job.
Why does the front bearing share a number with a Prelude?
Honda and Acura shared suspension architecture across several models of the era. The 510039 front number simply followed that shared design into the RSX.
Does the RSX front number match the Integra’s?
No. The Integra used a different number depending on year, and neither one matches the RSX front bearing.
Is a growling noise always the wheel bearing?
Not always. Tire wear and CV joint wear can produce similar sounds, so confirm with a proper inspection before replacing parts.
