The short version
- A Pontiac wheel bearing is a sourcing question first, because the brand ended in 2010 and dealer stock went with it.
- Every Pontiac has a General Motors twin still in production or recently so. Search that badge too.
- G6 and Malibu, Torrent and Equinox, Vibe and Matrix, Montana and Uplander are the pairs that matter.
- The hardware is ordinary bolt on GM hub units, so the job itself is not the problem.
Nothing about a Pontiac hub is unusual. What is unusual is that the badge on the car has not existed for over a decade, which changes how you shop rather than how you work.
Every one of these cars has a sibling with better parts coverage.
Finding a Pontiac wheel bearing
G6 shares with Malibu and Aura, and Torrent shares with Equinox. Vibe shares with the Toyota Matrix, and Montana with the GM minivans.
If a Pontiac listing looks thin or overpriced, the same hub under the sibling badge usually is not.
Matching numbers is on the cross reference page, and buying options are on the where to buy page.
The age problem
The newest Pontiac is well over a decade old, so every one of them has had years of water and salt at the knuckle bore.
Expect corrosion to be the difficulty rather than the bearing itself, and plan for a puller.
Those are on the corrosion page, the stuck removal page and the salt page.
Is it worth fixing
On a car of this age the honest question is whether the repair is proportionate to what the vehicle is worth.
A bolt on hub is one of the cheaper versions of this job, so the answer is usually yes.
It stops being yes when the knuckle is damaged too.
That decision is laid out on the worth fixing page and the bore repair page.
Pontiac wheel bearing options by model
| Model | Hub type | Sibling |
|---|---|---|
| G6 | Bolt on hub unit | Chevrolet Malibu |
| Grand Prix, Grand Am | Bolt on hub unit | Impala and Alero |
| Torrent | Bolt on hub unit | Chevrolet Equinox |
| Vibe | Bolt on hub unit | Toyota Matrix |
| Montana | Bolt on hub unit | GM minivans |
The Vibe row is the interesting one. That car is a Toyota underneath.
Search the Matrix listings rather than the GM ones.
The Chevrolet detail is on the Chevrolet page and the Toyota side on the Toyota page.
Doing the job
- Soak the bolts early, because age and salt are the real obstacles here.
- Pull the hub rather than hammering the flange.
- Clean the bore to bare metal and measure it before fitting anything.
- Leave the bore dry, since lubricating it removes the friction that resists creep.
- Check the other corners while you are under there, given the mileage.
Those are on the bore measurement page and the what else to check page.
Common questions
Can you still buy a Pontiac wheel bearing?
Easily, because these are ordinary GM hub units. Search the sibling badge if the Pontiac listing looks thin.
What is the sibling for my car?
G6 with Malibu, Torrent with Equinox, Vibe with the Toyota Matrix, Montana with the GM minivans.
Do I need a press?
No. These are bolt on hub units, so corrosion is the difficulty rather than press work.
Is it worth repairing an old Pontiac?
Usually, since a bolt on hub is a cheap version of this job. Less so if the knuckle bore is damaged too.
Why is the hub seized in?
Years of water and salt in the knuckle bore. Every one of these cars is old enough for that now.
Which Pontiacs ask about this most?
G6 and Grand Prix, then Torrent and Vibe.
Does the ABS light come on?
Often, since the wheel speed sensor is part of the hub on most of these.
