So do eBay and Amazon.

 

Yes, I just wanted to point that out. Thanks

 

So if I order a replacement front hub assembly to replace the one where the ABS sensor has failed, should I do both at the same time? The car only has 100,000 Km (~60,000 miles) on it but it is 14 or maybe 15 years old. How long do those front hub assemblies usually last?

 

No. Just replace the failed one. Highly variable life. The original could last longer than an unneeded replacement.

 

Or, if one has failed the other isn't far behind. However, much more likely a connector or wire problem since magnets and coils of wire don't usually wear out.

 

The variability of bearing life is high too. Lotsa bearing balls in there and if just one spalls or splits…

 

Careful ordering, the SS axles are differ size and splines then the LS/LT axles
the SS ANS sensor signals are different also

 

@Oldblue I've verified on three other websites that the SKF BR90317 front wheel hub assembly fits the HHR SS only. I'm pretty confident it's the right part. And SKF has a good reputation for making quality bearings. I'm sure it will be at least as good as OEM and IMO there's a good chance it will be of higher quality.
