The short version
- The G8 wheel bearing chart is short and Australian: 513280 front hubs for 2008 to 2009.
- The rear runs a pressed ball bearing, WB000027 in Timken’s book, not a bolt-on hub.
- Both ends serve the imported Holden Commodore underneath the badge.
- The same platform returned later as the Chevrolet SS, which keeps parts flowing.
Pontiac’s last great sedan was a Holden Commodore flown in from Australia, and its bearings never pretended otherwise. Two model years, one front number, and a rear that surprises people expecting another bolt-on hub.
The front: one number, two years
The G8 wheel bearing up front is the 513280 hub assembly for 2008 and 2009, V6 and V8 alike.
Timken lists the same application as HA590299, a branding difference rather than a different part.

The pressed rear
The Zeta platform’s independent rear carries a pressed bearing in the knuckle, so the rear job needs a press or a shop.
The procedure lives on the press-in page; budget accordingly.
The Commodore connection
Holden built this car for Australia first, which means Commodore VE listings and later Chevrolet SS listings often carry the same hardware. Cross-shopping those names keeps an orphan brand’s parts affordable.
The make overview is on the Pontiac page.
Driven like a muscle sedan
G8s survive because owners love them, and the GXP’s V8 loads the front bearings through every on-ramp. A hum that grows with cornering speed gets the weave test the same week, per the noise when turning page.
Diagnosing a G8 wheel bearing
- Weave at speed and place the hum front or rear.
- Rock each wheel at twelve and six.
- Front means 513280, a straightforward swap.
- Rear means press work, so plan the job.
- Search Commodore and SS listings when pricing.
The routine is on the checking page.
Common questions
Which G8 wheel bearing fits the front?
513280 for both years and every engine, GXP included.
Is the rear really pressed?
Yes. WB000027 goes into the knuckle with a press, unlike the bolt-on front.
Do Chevrolet SS parts fit?
The platform continued under that badge; listings overlap heavily. Confirm years.
Do I need a press?
Only for the rear. The front unbolts.
Does the V8 change anything?
No. Same listings, more load through them.
