The short version
- A Scion wheel bearing on the tC splits on whether the car is automatic or manual, which nothing else on this site does.
- 513257 is cited for automatic transaxle cars and 513258 for manual ones at the front.
- Everything here is a Toyota underneath, so Toyota listings are the wider market.
- The FR-S is the exception, because that one is a Subaru.
A transmission has nothing to do with how a wheel turns. On this car it changes the front hub anyway, because the two versions use different axles.
The transaxle split
On 2011 to 2016 tC models, 513257 is cited for automatic transaxle cars and 513258 for manual.
Nothing about the year or the trim separates them. You have to know which transmission the car has.
It is the only transmission based split recorded on this site, and it catches people who assume the front hub is downstream of everything.
Scion wheel bearing arrangements by model
| Model | Detail | Relative |
|---|---|---|
| tC | Front splits on transaxle | Toyota Camry family |
| xB | Bolt on hub unit | Toyota compact platform |
| iM | 513257 front, 512372 rear | Toyota Corolla |
| iQ | 512522 rear | Toyota iQ |
| FR-S | 513352 front | Subaru BRZ and Toyota 86 |
Cross referencing is on the cross reference page.
The FR-S is a Subaru
513352 is cited for the FR-S front, and the same number appears under the Toyota 86.
That car was engineered with Subaru, so it takes Subaru hardware rather than the usual Toyota parts.
Search under 86 and BRZ as well when a listing looks thin. The Subaru overview is on the Subaru page.
A discontinued badge with a live supply
Scion closed in 2016, which worries people shopping for parts. It should not.
The hubs were never Scion designs. They were Toyota parts fitted to cars with different badges, and Toyota kept building the relatives afterward.
The Toyota overview is on the Toyota page.
Light cars and impact damage
These are light and most ran small wheels with short sidewalls, which is a combination that passes impacts through.
On a car this light, most bearing failures trace back to an event rather than to accumulated mileage. Ask what it hit.
That is on the pothole page.
Diagnosing a Scion wheel bearing
- Check the transmission on a tC before you order anything.
- Find the Toyota equivalent, or the Subaru one on an FR-S.
- Ask what it has hit, since impact explains most failures here.
- Weave at road speed and note which side loads the noise.
- Rule out the tires before buying a hub.
Those are on the checking page and the tire noise page.
Common questions
Does the transmission really change a Scion wheel bearing?
On the tC yes. 513257 is cited for automatic cars and 513258 for manual at the front.
Why would that be?
The two versions use different axles, and the hub has to match the axle it receives.
Are parts hard to find for a discontinued make?
No. These are Toyota parts and Toyota kept building the relatives.
Is the FR-S the same as the others?
No. It is Subaru hardware and shares 513352 with the Toyota 86.
Do I need a press?
No. These use bolt on hub units.
Why did mine fail at low mileage?
Impact damage is the usual cause on light cars with short sidewalls.
Should I replace both sides?
Only what is worn.
