The short version
- The front Sonic wheel bearing is a press-in, 510119, on a car most people assume has bolt-on hubs.
- That same bearing serves the Trax, Encore and Spark EV, so the listings run deeper than the badge suggests.
- The rear is commonly listed as the 512438 hub.
- Coverage here is retail-verified; the car postdates the print catalogs entirely.
The surprise on this cheap little Chevy is up front. Where its Spark sibling bolts a hub on, the Sonic presses a bearing in, which quietly changes the whole repair plan.
The press-in front nobody expects
The front Sonic wheel bearing presses into the knuckle, and the same 510119 serves the Trax, the Buick Encore and the Spark EV.
Small car, corporate bearing, wide availability.

The repair math
A press-in front on a budget car sets up the same economics as the old Echo: cheap part, meaningful labor. The two-step route, pulling the knuckle yourself and paying only for the pressing, keeps the bill proportionate to the car.
That approach is on the press service page and the press-in bearing page.
The relatives worth searching
GM spread this bearing across its small-car range, so a search under any of the siblings finds the part.
The bolt-on-hubbed Spark plays by different rules, on the Spark page.
The make overview is on the Chevrolet page.
Diagnosing a Sonic wheel bearing
- Rule out the tires, the classic imitator on light cars.
- Weave at speed and follow the hum.
- Rock each wheel at twelve and six.
- Budget for the press before pulling a front apart.
- Search the sibling badges when pricing.
The routine is on the checking page and the tire noise page.
Common questions
Which Sonic wheel bearing do I need?
Front, the 510119 press-in. Rear, the commonly listed 512438 hub. Confirm by VIN.
Is the front really press-in?
Yes, unusually for the class. Plan the job accordingly.
Do Trax or Encore parts fit?
The front bearing is the same 510119. Match years and confirm.
Is the Spark the same?
No. The Spark uses bolt-on hubs with GM-only numbers, covered on its own page.
Is the rear easy?
Yes, a bolt-on hub, the friendly half of this car.
Is the car worth the front repair?
Done the two-step way, comfortably. Full shop pricing starts arguing with the car’s value.
