Just wondering, I was told that GM has now excluded the wheel bearings from the 100,000 mile warranty. Since mine is a 2009 with 77,000 miles does this mean my vehicle is still covered ??? The person said they thought it did not change until 2010 models, but was not for sure. Anyone who may have recently had some replaced please let me know. I really hate to pay out of pocket for this. Thanks,

Yours are covered. 2010 - 2011 are not.

Sorry to thread-jack, but why did they change the policy on the 2010 and 2011 models? Do you know if they changed anything about the bearings to make them better, or did they just decide to say "eh, screw em" to those who bought a '10,'11 vehicle?

ChevyMgr

They don't tell peons like me that kind of information.

Oh. Touche' I just didn't know if they had a different part number during the later years or anything. No big deal.

Just had my right bearing replaced yesterday!

I have 2009, 84k miles...Zero cost to me, so I'd say it's covered for you!

I'm sure numbers have changed but the hubs are problems with a lot car lines. I'm sure there is an answer as to why nobody can make a quality bearing with a low failure rate. I just don't know what it is.

My guess is a high quality low failure rate bearing could be manufactured, but it would cost more.

The part number hasn't been changed since the HHR debuted so it's unlikely that there's been a spec change or a vendor change-two reasons why GM changes part numbers.

The answer is to go back to a roller tapper bearing but fine one that has less drag.

It is not so much the quality as it is the type of bearing. With the rollers they use now it gives less contact on the bearing and a bearing thar rolls much more free. This helps in gas milage.

The price you pay is even with a good quality bearing the ball bearing takes much more abuse since all the force and pressure is focused on a small contact area.

The rollers never had an issue as they spread the force out over a larger area. But then they also produced more drag.

I have friends at Timken Bearing here locally and that is what I have been told. They have been looking for ways to make a better design that is stronger but it is difficult to keep them efficent.

There is alot of work going on here but so far there is no magic bullet to solve this delema.
