What type of signs do you observe when a wheel bearing is defective?

the bearing can be bad and no sound, jack up the car and rock the wheel in and out it should have no play

I do agree put the car on jack/stands/lift and freely spin the wheel and take a hold of the tire/wheel or rotor/drum top and bottom and push/pull for any play in the hub. If you hear a grinding noise or a rough resistant feel then after you have determined that you do not have a brake caliper or drum has hung up, the conclusion can be made that it is in fact a dad bearing. You will NOT be able to determine if you have a worn out bearing by driving the car and listening to the hum because the sound also could be a badly worn (uneven/knife/scalloped) tire. .02 [thumbsup]

can this woooing sound come from a rotor that needs skimming?

And how much play are we talking about with the tire?

No. It is either tire or bearing. Check bearing (lateral play/spins freely with caliper removed).

rotors also make that sound if something is rubbing against it eg a loose disk pad or some loose part

Sound but not a felt vibration while driving and not braking.

Bukkam...  [notworthy]

But doing that test two things, wheel bearing and ball joint... If you step on the brake while someone rocks the wheel up and down and the play goes away then its the wheel bearing. If the play is still there then its ball joint.

thanks Le4k^

Is it possible to remove the hub to determine for sure if the bearings are worn.

can I put the hub back on with the worn bearings so I can drive around and look for the right bearings?

Some units come sealed and are a wheel bearing and hub all in one, so you have to replace the whole thing. Post which car it is year and model and maybe someone can answer that question for you.

it is a 94 honda prelude
I found the procedure online.  Have to replace entire hub.

The hub costs 16,000 each at superior.  Checked it online. It's about 163 us so basically the same 16000 each
looks like I just have to save until I can afford it.

Will the wheel drop off if I don't change the hub?

Cause wheel bearing, hub and maybe wheel speed sensor is all one unit.

I dislike this kind, wheel speed sensor fault diagnosis is harder to confirm and replace  [yuk]

Had to change wheel bearings the other day. 1stly, there was no play in the wheel or anything like that. Secondly, once the hub was removed it was a relatively easy job to press out the old bearing and press in the new one. There was no sound coming from the old bearings. Its best to pull down the entire hub and check it then. Can't say much about that prelude hub but my speed sensor port and everything came off just fine. Hub also needs to be checked for excessive wear. Oh, yea I drive a Toyota...

Huh, no noise no play. Did you walk by the car one day and you head it say, "hey you need to change me" come on man. If a bearing is bad it will either make a noise or the bearing will have movement in the race or both. If it is a sealed ball or roller bearing it will more make a noise that have excessive movement unless the carrier is worn. Either way the part will make a noise or have a movement. If either is not present, well IMHO you changed a bearing that didnt need to be changed.
