The short version
- The two xB generations share nothing: the boxy 2004 to 2006 car runs Echo hardware, the bigger 2008 onward car has its own.
- First generation: xB wheel bearing 510062 press-in front, 512209 rear hub.
- Second generation front: the 513257 bolt-on hub.
- One catalog lumps both generations under one listing, which is exactly the mistake to avoid.
Scion changed the xB completely in 2008 and kept the name, which still causes wrong deliveries. The first box is an Echo in streetwear. The second is a heavier car on different bones.
Generation one is an Echo underneath
The first xB wheel bearing set matches the Toyota Echo: 510062 pressed into the front knuckle, 512209 bolt-on hub at the rear.
Everything on the Echo page about cheap parts and press logistics applies here verbatim.
That donor car is covered on the Echo page.

The catalog disagreement
One catalog lists the first generation numbers straight through 2009, ignoring the redesign. The other splits 2008 onward to the 513257 hub.
The split matches the actual redesign, so this page follows it. A 2008 onward car should be matched against 513257, not the Echo-era parts.
Second generation, easier job
The 2008 onward front is a bolt-on hub, which removes the press from the job entirely. Three bolts behind the knuckle, a stubborn rusted interface, and done.
The related tC runs different numbers again, covered on the tC page, and the make overview is on the Scion page.
Diagnosing an xB wheel bearing
- Establish the generation first, since nothing interchanges.
- Weave at speed and place the hum by corner.
- Rock the wheel at twelve and six.
- Rule out tires, especially on the light first car.
- On a first generation front, plan the press before dismantling.
The routine is on the checking page and the tire noise page.
Common questions
Which xB wheel bearing fits my car?
2004 to 2006: 510062 front, 512209 rear. 2008 onward: 513257 front hub.
Why do listings disagree about 2008 and 2009?
One catalog missed the redesign. Match the 513257 hub on the second generation body.
Do Echo parts fit?
On the first generation, yes, that is the platform. On the second, no.
Do I need a press?
First generation front, yes. Second generation front and all rears bolt on.
Is the xA the same?
The xA shares the first generation hardware, so those numbers serve it too.
What fails first on these?
Nothing bearing-specific; they follow ordinary small-Toyota wear. Diagnose by symptom, not reputation.
