    Did I get something wrong?There is a humming sound in the car while driving. It is very obvious when the speed is 50km/h, and it can also be heard at other speeds. It does not seem to be related to the accelerator. I took a video.

    Get something wrong???? What did you do?
    No whining heard, just the normal road/tire/wind noise.

    This is a used car. I don't know what the previous owner did. I have adjusted the toe and lubricated the brake caliper guide and piston. I suspect the sound comes from a bearing. I wonder if this sound is normal?
    The whining sound is actually more obvious than in the video

    "IF" it's a wheel bearing, you'll have to pull the axels, and press the brake pads back
    so you can rotate the hub(s) and listen for grinding. Though you might be able to skip pressing
    the pads back.
    With the rears, you also may be able to spin them without removing the calipers.
