Humming/Vibration sound at high speed

[cLaw]

No clue where to post this but I've had this sound in my car that is easily reproducable and gets louder with speed so I figured maybe wheels/brakes??

The sound is like a vibration/humming but you don't feel the vibration. You can only hear something, kinda like sticking your finger in a fan and as the fan spins faster the vibration gets louder.

A couple of things to note, it will never happen close to a cold start. If I start the car and theoretically go 60 within a few minutes, there will be no vibration or sound. This is something that only starts happening after you've been driving for a little. Secondly, it will only happen when off the throttle. You can step on it and hit 120 and there will be no sound, but as soon as you let off the gas it will begin the vibration until you either slow down or let on the throttle again.

Lastly the sound is kinda hard to tell where it is coming from exactly. From the driver seat it sounded like my front left wheel, my passenger said he couldn't tell it just sounded like the front of the car. When I lower my window you can't hear it at all, as the wind would drown it out instantly, even at lower speeds (40/50mph) the sound just dissapears when you roll the window down. Seems like it can only be heard from the cabin.

This sound does not do anything else, it doesn't change the ride quality, steering, breaking, etc...Its just a sound from what I know.

I've also checked my logs on my jb4 and those are all clean as well.

That is the most amount of info I can think of at this point.

Strange. Almost sounds like hub bearing(s) to me. What year and how many miles are on the car? The only thing that's kinda throwing me off about it being hub bearings is that it's not always happening. Usually for those it doesn't matter if the car is cold or hot or if you're going 30 or 100, accelerating or decelerating.

21 stinger gt1 40k miles.

Yea, strictly never happens within 10-20min after cold start and also very strict on the fact that it only happens when off throttle. To the point where I've had people in the car and literally put my foot down the sliiightest bit just to give it like 1% throttle and the vibration cut out lol.

It is decently loud enough where someone who knows about cars would probably ask what the sound is. Any one else its kinda ignorable

So strange to me

When our accord developed failing rear bearings, the sensation was a hum that got progressively louder as speed increased. At 35 mph, nearly sounded like in a prop plane.

The failure was progressive, over the course of about a year (4K miles), barely noticeable at first. Eventually dealer replaced both rear bearings and silence returned.

Temperature was never a factor, though because of higher idle at cold one may not hear it as much at lower speeds.

@OP, car is under warranty, let them figure it out.

Yea true...just dont want to get f&*%ed with by the dealer for 300 years because the one near me usually doesnt have a clue whats going on. Just prefer to know the issue for sure. Maybe ill go to a local shop near me to find the issue itself and then go to the dealer for the work. Just hate my dealer lol

Also, the only thing that confuses me is the throttle. Im not the most mechanically inclined but I dont understand how engaging the throttle by like 1% completely removes the sound. Just so odd

When you add torque it takes some of the load off the bearings, usually you can tell by giving side movement and torque.
If the bearing noise goes away when you turn this also provides relief on the bearings or added strain depending on which bearing is bad.
Sounds like a bearing to me as well, when cold there is less play until they warm up and expand the metal. It will usually get louder and the temperature will have no effect.

Thank you! This also only happens at highway speeds so I could never really test with turning. I would say around 50-60 and above is when you can hear it for the most part.

Bingo, on a prior car I had a rear bearing go bad on one side, and depending on which way the drivetrain was loaded (mild accel vs. engine braking) it would be more or less noticeable. Pitching the car into a steady curve one way or the other would also shift the weight onto or off of it enough to hear/feel the change.

Hi OP have you been able to figure out the problem. I have something similar. Thanks

Changed brake pads and all 4 tires since then, problem still there. Genuinely just been ignoring it lol

Also dealership said wheel bearings were fine but then again that’s the dealership so Im not sure. Problem hasn’t gotten worse or better just same old

I have done alignment and a new set of wheels and tires. It did help minimize the noise but I can still hear something in the background all the time. Now it also depends on surface of the road. I have not checked wheel bearing yet but planning to get that checked out by dealers next servicing. I attached a video recording of the sound I was having. Now it’s much better but I kind of want to eliminate that for good lol

Any updates? I may be having a similar issue. Allegedly my wheels were bent and got them fixed, but still there. Then I thought ok maybe tires, got the front replaced and still there. My next thought is to get the bearings inspected at the dealer

Changed the rims, tires and got alignment done. I also found side skirts or underbody panels have some gaps with one bolt loose. I pushed it back up as much as possible. Found a loose nut inside the panel as well. After all these steps it’s much better now I only hear faint noise at some road surface but most times it’s not there. If it gets worse again then I will let dealer check the bearings. Only reason I am not suspecting to be bearing because noise is dependent on road surface not speed. I think it’s tire noise getting into some air vents or under body panel gap creating some sort of resonance.

Update - I went to a trusted dealer and they diagnosed it the noise to be coming from transfer case and propeller shaft. They ordered the parts so I am waiting for those to arrive. Just fyi

 

[Daeric23]

Really? Wow. How many miles you got? Any reason they would’ve seen those parts fail? @mirza7789

I have 44k km on it. I am not sure what would happen to those parts to make a noise. I guess I will know dealership replaces it and can take a look inside those parts maybe. I heard many cases of undiagnosed low hum with stinger owners but it might be because of that. Well at least I have warranty.

@mirza7789 Nice! I may recommend this to my dealer when it goes in. I noticed above that the noise would change depending on the road, mine too. It gets louder on concrete versus asphalt. Would you also agree?

I also hear my noise in the front of the vehicle, not the rear. I can hear the noise as low as 10mph onwards.

Also how long was your repair? In the shop for a few days? And how long did it take to get diagnosed? Was it pretty obvious? Anything to help me expedite and help the dealer find the issue

Yes mine noise was more pronounced on uneven roads and concrete less so on smoother asphalt. Noise was only coming from the front and I could hear it at any speed. My car also developed jerky shifts and hesitant on accelerating when I was waiting for parts. I realized later that I ran winter tires on the front that little bit outside the factory size 235-40 instead of 225-40 rear being the same. Maybe that’s why my transfer case developed the hum. But propeller shaft was also noisy for some reason. Def ask your dealer to check those areas.
