The short version
- A G6 wheel bearing splits on how many studs the hub has, four or five, and then again on ABS.
- 513206 is cited for a five stud hub with ABS and 513204 for the four stud version.
- Non ABS cars take 513205, so two questions have to be answered before you order.
- Counting studs takes five seconds and settles half of it.
General Motors sold this car in enough configurations that the wheel itself changed. A base car and a loaded one did not always share a bolt pattern.
The hub carries those studs, so a different pattern means a different part.
Count the studs
On 2007 to 2010 cars, 513206 is cited for a five stud hub with four wheel ABS and 513204 for the four stud version with ABS.
Look at the wheel. The count is not a trim detail you have to look up.
Then check ABS
513205 is cited for four stud non ABS cars in the same years.
ABS moved between standard and optional across this range, so the model year does not settle it.

A discontinued badge, a live parts supply
Pontiac stopped existing in 2010, which worries people shopping for parts. It should not.
These hubs are shared General Motors components, and the aftermarket supplies them in volume because the cars are still on the road. A dead badge is not a dead part number.
The make overview is on the Pontiac page.
What these cost to fix
Bolt on hubs and a common platform keep this cheap by any standard, and it is one of the more approachable jobs for a first attempt.
The saving on the cheapest parts comes out of the seal and the encoder ring, and a poor encoder lights the dash on the first drive.
Those are on the price tiers page and the ABS light page.
Diagnosing a G6 wheel bearing
- Count the wheel studs before you order anything.
- Check whether the car has ABS, since that splits the parts again.
- Weave at road speed and note which side loads the noise.
- Rock the wheel at twelve and six.
- Rule out the tires before buying a hub.
Those are on the checking page and the tire noise page.
Common questions
How do I choose a G6 wheel bearing?
Count the studs first, then check ABS. Those two answers narrow it to one number.
Why would the stud count differ on one model?
The car was sold with more than one wheel and bolt pattern, and the hub carries the studs.
Can I still get parts for a discontinued make?
Yes. These are shared General Motors hubs supplied widely by the aftermarket.
Does ABS really change the part?
On these years yes, because the encoder ring is built into the hub.
Do I need a press?
No. These use bolt on hub units.
Is a cheap hub worth it?
The savings come out of the seal and the encoder. Buy a step up on a job this cheap.
Should I replace both sides?
Only what is worn.
