The short version
- A Saturn wheel bearing is a General Motors part, and the Ion splits on stud count and ABS exactly like a Cobalt.
- 513204 is cited for four stud hubs with ABS, 513206 for five stud with ABS and 513205 for four stud without.
- The Vue shares 513277 with the Buick Enclave, so the crossover parts come from a much larger family.
- The badge closed in 2010, which changes nothing about supply.
Saturn was a General Motors brand with its own dealers, not its own engineering. The hubs came out of the same bins as everything else.
That is the useful thing to know when a search under the badge looks thin.
The Ion splits like a Cobalt
513204 is cited for four stud hubs with four wheel ABS, 513206 for five stud hubs with ABS and 513205 for four stud without.
The rear follows the same logic with 512247, 512248 and 512250.
Those are the same numbers the Chevrolet Cobalt and Pontiac G6 use, covered on the Cobalt page.

The Outlook is an Enclave
The same number is cited for the Buick Enclave, the Chevrolet Traverse and the GMC Acadia.
Four badges on one hub means good supply and real price variation between listings.
That family is covered on the Enclave page.
A closed badge with a live supply
General Motors wound the brand down in 2010, which makes people assume parts will be scarce and expensive.
They are not. Every hub here is a shared component still supplied in volume, because the relatives kept selling for years afterward.
A dead badge is not a dead part number. Search the number instead.
The Vue is two different vehicles
The earlier Vue and the later one were separate designs, and one of them used a Honda engine.
Establish which one you have before ordering anything, because the year alone can mislead you at the changeover.
The Chevrolet overview is on the Chevrolet page.
Diagnosing a Saturn wheel bearing
- Count the wheel studs on an Ion before ordering.
- Check for ABS, since it splits the parts again.
- Find the General Motors relative and search that too.
- Weave at road speed and note which side loads the noise.
- Rule out the tires before buying a hub.
Those are on the checking page and the tire noise page.
Common questions
Can I still get a Saturn wheel bearing?
Yes. These are shared General Motors hubs, supplied widely because the relatives kept selling.
How do I choose for an Ion?
Count the studs, then check ABS. The same three numbers cover the Cobalt and G6.
What does the Outlook share with?
513277 is cited for the Buick Enclave, Chevrolet Traverse and GMC Acadia as well.
Why does stud count differ within a model?
The cars were sold with more than one wheel and bolt pattern, and the hub carries the studs.
Do I need a press?
No. These use bolt on hub units.
Does ABS really change the part?
Yes, because the encoder ring is built into the hub.
Should I replace both sides?
Only what is worn.
