Noise from passenger side rear wheel?

[RyanHeo]

Hello.

I have an 2001 Acura Cl which has 112k on it. It makes a kind of humming or whistle noise from rear wheel. The noise occure from 5 mph. It is getting louder when the car is faster. I guess it is from the rear hub bearing. What do you guys think about this?

Thanks.

Start by rotating the tires to rule out a tire. Note if the noise gets louder or softer with applying the brakes or making a turn. (Check left and right turns.) Jack up that corner and spin and rock the wheel by hand and ensure the parking brake is releasing. Then report back.

I don't think any turns make the noise worse because it is from rear wheel.

Thanks.

Probably the bearing, but could be brakes.

Thanks.

What I was suggesting is to see if the noise becomes louder when the weight is transferred to one side when making a long steady turn, like on an exit ramp. If it does get louder, it's probably the wheel bearing. But check the other things first to rule them out.
