Default 05 Chevy Aveo: Brakes or Bearing?

While traveling on I-20 East, going well over the speed limit (75 MPH, Posted), just outside of Abilene, TX, the left wheel started howling and pulled to the left. Weirdest part about this, it did it on and off. It was not constant.

I slowed to the speed limit, and pulled over at the nearest rest stop to check the wheel bearing. The wheel didn't budge. I called a mechanic buddy and he thought the same, that it may be the wheel bearing.

I drove it into Abilene (driving the speed limit), no sound and no pulling, and had Firestone check it out. They confirmed, by driving and inspecting it by moving the wheel, that it's not the wheel bearing.

So, during the rest of my 3000 mile trip, it didn't do it once. Not a single time that this issue came back, until on our way back home.

This is the interesting bit; driving down AZ-87, just outside of Mesa, AZ, it came back. Out of curiosity, I tapped the brakes, and it stopped. Never once came up again. I drove the car consistently over 75 MPH the rest of the way home, over 220 miles.

Here's some more info, if it helps; driving at highway speeds, the right brakes engage first.

I am so completely baffled, that it hurt my head typing this up.

Any help is appreciated.

But, it happened twice on the trip. The left front bakes are still good, I think. I have not visually inspected those pads, yet.

I had something similiar with my wagon, it turned out to be the flex brake hose, the rubber would swell under heat and force the caliper to drag, by the time I got home, pulled the wheel it would cool down and release, but the glazing on the rotor told me better. Ended up changing that hose and solved all the problems.

Thats possible as well. But that wouldn't make it howl.

The howling is what led me to the wheel bearing in the first place. That's why I'm so confused.

I still suspect wheel bearing. You need to check it at the spring and compare it to the other side. Any rain or bad water on your trip?

Neither. As I stated, I checked the wheel bearing by lifting the car and wiggling the wheel. Seemed solid.

Like I said needs to be checked at the spring. Wheel bearing noise can't always be found by a shake down.
