If the noise changes pitch when turning slightly either direction then it is a hub bearing.They start to sound like a off road tire noise.
easy change if you are mechanically able to do it cause it is not a pressed hub.
Hope this helps,

 

If the noise gets worse when you are turning one direction and it does not when turning the other, it is almost definitely the wheel / hub bearings. I've had to replace too many of those in my older cars and that was always a dead giveaway

An experienced mechanic will be able to tell by putting the car up on a rack and turning the wheels. My father has had his own shop since the mid 80's he has always said that you should never tell a mechanic to replace a part if you are not sure that is the part that is failing. Most shops will change the part you request and give it back to you without even looking at any other potential causes for your issue. If you describe the problem and ask them to find the cause then you put the onus on them to actually diagnose the issue. A good \ honest mechanic will find it and let you exactly what you need to replace,and thus prevent you from spending a fortune on replacing parts that do not really need to be replaced.

Now the hard part is finding a a good \ honest mechanic that you can trust. He had many loyal customers who always came back to him. It provided for our family for over 20 years before a motorcycle accident forced his retirement. Even after he retired they began to call me and asked me to quit my job to reopen his shop. I'm not a mechanic though, I just play one occasionally on the weekend.

Good luck in your search. My hhr was initially a disappointment to me, but after I worked out most of my issues it has been relatively trouble free for the last 40k miles.

 

If the POS is under 5 years then the hub bearings are covered by Power Train Warranty.

A common cause for leaks at the caliper hoses is that the calipers were left hanging by the hose instead of being secured during a brake job. Have you had one done?

 

He's got rear drums(failure point was at the right rear), and from the description it sounds like the flex line leading to the wheel cylinder broke at the connection to the hard line on the rear axle, I'm thinking corrosion is the cause.

But you do have a valid point, leave a caliper hanging by the brake line, is asking for trouble....but you still see techs doing it with when they are too lazy to tie the caliper up.

 

Thanks, I will run it up to the dealer now and see what they say. I did my front brakes and hung the calipers with a strap, the rear is drums. thanks for the input everyone.

 

Keep us posted, and you may also think about "firing" your current dealer and going somewhere else if they can't adequately diagnose the issues correctly the first time.

 

And the intermittent TC and ABS lights ... a broken/leaking brake hose. Do ya think they could be related? Not to mention bad bearings (they have sensors relating to both TC and ABS).

Sounds to me like a undisclosed wreck may be the problem.

 

My bad I missed that it was a rear brake line. It's a rare failure for sure.

 

Good news so far. The dealer is getting parts to replace both rear bearings. They have fixed the brake line for a little over $200 ( I will have to talk to them about vibration from wheel bearing causing that issue and if they can cover that as related)

The said they will take it for a drive after replacing the rear bearings to see if the front bearings are bad. They also mentioned that one of my front struts is leaking oil.

Hopefully this stuff will fix the road noise as that is my biggest issue with the car now.

 

Keep us posted, and make sure they check the tires for unusual wear patterns that might have started due to the bad bearings. Sadly, once tires start to wear "funny" they'll do it until they wear out, so you might have to swap them around to different positions on the vehicle to minimize any noise coming from them.
