The short version
- The 2009 Pontiac G8 rear wheel bearing is WB000027, a pressed ball bearing shared with 2008.
- The front hub carries part number 513280 on every engine.
- Pontiac built the G8 for only two model years, and the listings do not change.
- The rear presses into the housing instead of bolting on, so the job takes more shop time.
Pontiac only built the G8 for two model years, 2008 and 2009. The rear bearing presses into the housing instead of bolting on as a hub unit. That difference matters more than the model year does.

This page covers the 2008-2009 Pontiac G8: 2008, 2009. Other years live on the main Pontiac G8 wheel bearing page.
The 2009 Pontiac G8 rear wheel bearing, and the 2008 version alike, is a pressed unit, not a bolt on hub. The job needs a press instead of a socket set.
Budget for that difference before starting the work. See press in wheel bearing for what the process involves.
Year by year
2008 and 2009 share every listing in this table. The model year does not change which part number applies.
The front hub is 513280 both years, regardless of engine. The rear stays WB000027 for the same span.
Anyone chasing a 2009 Pontiac G8 rear wheel bearing gets the same number a 2008 shopper would get.
Two years, one listing set
Pontiac sold the G8 for 2008 and 2009 only. There is no later run splitting the front or rear numbers apart.
The front stays a hub on every engine. The rear keeps the pressed design that some rear positions use instead of a hub; see drive type and wheel bearings for background.
Shoppers land on the same two rows whether they search 2008 or 2009.
Diagnosing a Pontiac G8 wheel bearing
- Listen for the noise. A failing bearing usually growls or hums, and the sound changes with speed, not engine RPM. See wheel bearing noise on turns for how the pitch shifts.
- Rule out the tires first. Cupped or unevenly worn tires can mimic a bearing growl. Compare against tire noise or wheel bearing to sort the two apart.
- Check for play. With the wheel off the ground, grab it top and bottom and rock it. How to check a wheel bearing covers the full routine.
- Watch the dash. A worn bearing can trip the ABS light if it disturbs the sensor. A bad bearing and the ABS light explains the link.
- Match the number before ordering. Confirm the position, front or rear, then order 513280 or WB000027.
