Default Checking Wheel Bearings

'03 Camry V6, 32K mi. Getting a low pitched whine from front. At first
thought it was tire tread noise as I had just rotated. But it is there
hot or cold, wet or dry, any type of pavement, even in neutral
coasting.

Is there any way to check wheel bearings?

It is under 5-yr powertrain warranty, but they won't do anything until
the wheel falls off.

==================
You can check axial play with a dial indicator, but suggest first try
turning slightly at different speeds to cause the vehicle weight to
transfer from side to side. If you're hearing a wheel bearing noise as
opposed to some other driveline whine, the noise should change as the
weight transfers and shifts from side to side.

Does the pitch change as speed changes?

Wheel bearing noise gets progressively worse and changes in loudness over
gentle undulations in the road as the weight on said bearing changes with
suspension travel, but differential gear noise (pinion and crownwheel) will
come in at certain speeds, and doesnt change loudness, as a rule. My '96 has
some diff hum, and it sounds the same as you have described. If it is diff,
its not a problem as long as it doesnt change in loudness or character. A
diff which is self destructing will give plenty of warning :-)

Another TN Camry member had a wheel bearing fail at low mileage so it is
possible for it to go bad and the dealer to fix it. If a wheel bearing
it will get louder as the mileage adds up.

As Daniel states the dealer can check runout with a indicator, it is
all in the service manual.

Would still check the tires as this seemed to happen with the rotation.
Tires can start making noise as they wear.

There are several ways to check wheel bearings.With your running car put
your hand on the bumper and see if it vibrates you will be able to tell,
when you are going fairly fast does your car sound like a train and jack
up your car a little bit and see if your tire has play in it.
