So I took the buffalo to boston over the weekend. That’s 12 total hours of driving and about 900 miles. The drive went well minus a little winter weather and my car starting to make a noise. It’s like a mechanical sound, not quite grinding but kind of like gears or something but not like gears should sound.
!!! UNKNOWN CONTENT TYPE !!!
Best I could do to capture the sound. It really starts about 20mph gets loudest at 45 to 55, then settles to a drone.
I don’t have any shakes, vibrations or other noises. My mpg isn’t being effected and the car feels fine.
Thoughts?

They’re all good wheel bearings brent

Wheel bearing noise will typically be more pronounced when you shift weight to that side. Louder on the left turning right, quieter turning left for a left bearing, etc.

Yeah that doesn’t happen. Turning makes no change in the noise. Any thoughts on. What this could be? My alignment is off a touch it noticed it doesn’t track straight any more but slowly wonders. Could that just be tire noise caused by bad alignment? I do have knobby snow tires on.

Could something be rubbing on a tire?

You should feel wheel bearings through the steering wheel, noise when you turn towards that side, quiet when you turn away.. grinding/rumbling with speed but not rpm.
That constant drone sounds like something else..

haha ok, got it. so the bearing on fine you think. any ideas?

no I checked that. there’s nothing rubbing on the tire. I do have knobby snow tires though and the alignment seems to be off a touch. it slowly wonders vs tracking straight. could that just be the tire not sitting right any more and the tread getting used differently?

check your wheelwells/mudflaps and undertrays.. wouldn’t be the first car to make weird noises during winter driving.

yeah I’m not getting feed back from the wheel, it’s as smooth as always. and there’s not noises turning one way or another.

Oh I think it needs to be replaced, but it’s still a Good Bearing because it loves you.

Very possibly some tire issue like cupping caused by current or previous balance issues or alignment.

yeah I’m starting to think this. I keep checking my tire thread but i’m not feeling or noticing any strange wear, yet. The noise just started over the weekend and I changed the oil when I got the tire and that’s not due for a change for another thousand miles. so they have like 3000 miles on them tops.

You might have just lost a tire weight. It happens, particularly with clip-ons.

If the wheels and tires are clear, I would check other rotating components. Something is hanging out where it shouldn’t be.
In my experience, a bad wheel bearing sounds like stones in a coffee grinder. It’s bad. This sounds more like something is rubbing.
It’s like the scene in Crocodile Dundee when he calls the bats with that boomerang on a string. That’s what this sounds like.
Watch out for bats.

It could be any of the rotating bits, tires, wheel bearings, drive axles etc...

While it’s droning, put it in neutral so the revs drop. If there is no sudden change in the tone of the drone (other than the loss of speed you may have for the 5 seconds or so) then you can rule out anything related to the engine.
If it matches road speed (which is sounds like it does), I would look at tires and wheel bearings first.
To check tires: Try rotating them, or replacing one at a time with the spare.
To check bearings: lock steering wheel, then jack up each corner of the car. wiggle the tire/wheel back and forth at 3&9:00, then 12&6:00. Any play would point towards wheel bearings.
Is it one side or the other?

it’s really only coming from the drivers side. I have confirmed it’s definitely not engine or trans related. the sound makes no change based on revs or gear.

i think wheel bearings are a screechy nails on a chalk board sound. Maybe check your disc brake shrounds. Maybe there is something stuck in them. I had bent one of mine so it rubbed on the disc making me think the wheel bearing was making noise.

Don’t eliminate transmission so quickly.... That driveshaft is connected to the differential, which (and it’s bearings) move at road speed.
It’s likely tire/wheel bearing, tho.
If your tires are the same size front/rear, try swapping both on the driver’s side, or put the spare on the left front for a few miles. See if that gets rid of the noise.

GM was notorious for a few years where wheel bearings would go around 100K. You should check the wheel bearings with the 12 and 6 wiggle test. By any chance is the ABS light on? They usually go together.
Otherwise, is there any chance that noise changes with wind gusts? I had a poorly installed windshield gasket come out at buzz at higher speeds, but was not apparent at low speeds, it was very hard to figure out what was buzzing... It sounds kind of plastick-y, like a loose wheel arch or something like that.
Good luck finding it!

yes, same sire and same wear. bought all new snows this year. I’ll see if I can swap ‘em might have to wait a few days as there’s a nor’easter about to bash us with 18 inches over the next day.

Definitely sounds tire related but I have had wheel bearing issues in my Truck that have sounded like a drone. I know snowmageddon 2017 is coming but i would rotate tires around if you can and try to find a flat surface and see how they roll, left, right, wont stand at all, or have a gap in between the center of the tire.
The other way to tell if its a wheel bearing is to stress it out, meaning put maximum force on it. One of the safer ways to do this is find an empty lot, lock your steering wheel one way (left) and accelerate, then let the weight transfer to the opposite side (right) and then brake. The do this the opposite way and listen for grinding or popping. By doing this you are putting angular force as well as rolling force on the bearing and putting it through alot of stress. This can also help diagnose if its the tires as you are at lower speeds and putting force on the edge of the tire so the sound might go away and be replaced with the tire whining/screeching, key word though MIGHT.
Also side note if your ABS light does come on or is engaging randomly, more often than not its the wheel bearing. There are other factors that may cause an ABS light but most of the time when a suspected wheel bearing is going bad the wheel speed sensor will go bad with it/or read wrong causing a fault in the ABS, and triggering the light.

Ok did this on break. no popping or grinding noises. the only change in noise was my tires did screech. so what does that mean? it’s most likely a tire balance alignment issue?

03/13/2017 at 16:23, STARS: 0
That is definitely what i would lean to. I mean you put the maximum force the car would see on each side and if it didnt aggravate or cause the sound to get louder I dont think its the wheel bearing. Now with cars they can always prove you wrong but I would look into the tires and how they are wearing.
Another thing to kind of help rule out the wheel bearing is since this has happened, does it always does it? Even when its cold/after it sat awhile? Reason why i say this is because if the wheel bearing is bad, friction becomes the enemy and heats the hub up over time causing the sound/issue to happen. This doent prove its the wheel bearing ether because as you drive you are also putting heat into your tires.

yes, it’s a constant. from about 15 mph it starts gets louder between 45 -55 then settles down to a lower drone above 55. Oh it does get louder when breaking. but mostly only when passing the 55 to 45 mark again. so if i slow down from 60 it get’s louder then quieter. just like when i speed up. only in reverse. it’s not louder the whole time.
"Shift24" (the-nope)
03/13/2017 at 17:33, STARS: 0
Yeah i would still lean toward tires, as you are breaking you are transferring weight to the front wheels and adding force to the front tires. Also right around 45mph is where rolling resistance changes and increase dramatically. Even so like I said earlier you are also adding force to the bearings when braking but I wouldnt think it would be as much as the tests you did.
And I dont mean to undo everything we have talked about but wheel bearings are very very hard to diagnose. I Don’t recommend doing this but this is how far it takes sometimes to find out the issue . Even Timken, one of the best wheel bearing manufacturers, has you go through a complex way of checking them . I know these might not help your situation but from my experience, what it sounds like, and even what everyone else is saying I would trouble shoot the tires before the wheel bearings.
