Whirling noise at certain speeds

    2008 Scion TC...

    Been having an issue where a whirling noise is coming from what sounds like the front of my car. Noise is really noticeable, even with the radio on, when going 50mph and 65mph. Can still hear the noise going around 75mhp, but it is not as loud. When I drop below 45mhp, can hardly hear it at all...if at all

    Couple months ago, I had the front strutts, back sway bars, and front driver side wheel bearing replacing. Had them do a test drive with me and they said the noise was possible caused by the tires having a few flat spots. So I was just going to deal with it until I got new tires....

    So fast forward to day...the noise is still there and does not change pitch or sound if I am going on a nice smooth road, or if the road is bumpy. Figured if it was the tire, the noise would change depending on the road and the type of contact the tire was making with the road. Also I noticed today when driving at around 65mph, the noise got a little softer, then a little louder, little softer...

    Got an appointment on Monday to get my car looked at. Besides getting the whirling noise looked at, again, I need the back struts and from sway bars replaced. Car has about 130k miles on it so that is normal. Just curious on what could be causing the whirling noise and and opinions.

    thanks
    Are your tires balanced?
    By whirling do they sound like a helicopter

    Tired are balanced. They did it last time it was at the shop.

    Sounds like this...but this vid is when the car is idle. Mine does not do this while idle, but what I stated in my original post.

    It sounds like the wheel bearing is bad. if you steer left or right you should notice more or less noise depending on the steering load. I had a similar issue with a bearing going bad after 21k.

    They were checked last time I had my car in. One was bad, but the other one tested fine. And wouldnt a bad wheel bearing sound more like it was grinding and get louder faster you go?

    depends how it was defective. It could make screeching, rumbling, groaning, or grumbling noises. When mine were bad they made a low pitch roar, almost could mistake it for tire tread noise. Plus I had a vibration that would go away if I steering in the opposite direction of that tire. Both wheel bearings were bad. And the old test where you jack up the car then push/pull the tire at 12'oclock and 6'oclock positions never showed a thing!

    Chances are you have another bad wheel bearing like mine. Had one replaced, the vibration was still there, other replaced, no more issues.

    EDIT: just like cassman said, steering in another direction will lessen the vibration, try that and see.

    Car does not vibrate. Just the noise from the front is all.
    Water pump? How many miles

    Have you every changed the water pump and belts and pulleys?

    No, but the belts were checked when it was in the shop last. I just dropped the car off this morning so should know what the problem is in a little while. Thinking either a bearing or the water pump.

    When I find out what is wrong with it, I will post back here.

    Thanks
    Shop says everything checks out. Says I do have some wheel bearing issues but they cannot pinpoint which one. So I am going to keep driving and listening to see if it gets worse. Says the noise coming from the front could be partially related to the tires so will get those replaced before fall.

    Strutts, say bars, water pump, and everything else checks out.

    nice that you were finally able to narrow the field down to that it is the wheel bearings. Is it possible to make a video of this noise? Safely, of course. I'm thinking it was like mine, got one replaced, vibration still partially there, replaced the other side, no more issues. I bet it's the one that wasn't replaced yet.
    Most likely its a wheel bearing, i went through 3 so far and cant think of anything else that would create so much noise.

    You can pint point which wheel it is by lifting one wheel off the ground at a time and putting your car into 5th or D gear. Give it a little bit of gas to simulate 45-70mph drive. If it is a wheel bearing- you will hear it.
    *PLEASE* use jack stand and wheel blocks, i hope you bright enough to realize how badly this can go.

    Only had the driver front bearing replaced. The rest are the originals. I trust the shop I took the car to. Family has been going to it for decades and they wouldnt let me drive it if it was dangerous. I need new tires in a couple months and will have them check it then.

    Will try and get a vid to record the sound. Have to be careful as it is not legal to operate the phone while driving where I live. Sometimes the sound is loader but gets fainter and hardly noticeable around 50 and below. And tapers off around 70/75. Loudest at 65. Car does not vibrate....just the noise.

    could be either the tires or the wheel bearings. The first thought I had was sounded like a flat spotted tire. But if that was the case you should be feeling a vibration which you said you're not. So then only leaves the wheel bearings. Thanks for making the video.. Others will be able to view it and give their opinions.

    Going to get new tires in a couple months so will report back and post if that fixed/helped the noise. Video will stay up as I have no reason to take it down and I hate when I am trying to find a video of my problem and I can find nothing and what I do find, has no updates.
    okay well post up when you get the tires later this year..
    Just reporting in like I said I would....

    Got my tired replaced, finally, last week. The howl, hum, and wobbling noises are no more. Car is quiet again. Amazing the sound tires can cause.
