Slight Vibration and Noise - Help

[floyd0101]

Hello -

My 2012 Hyundai Genesis (57,000 miles) has gone through a long winter here in NE OHIO. I struck a pot hole and bent a wheel a month or so ago - this is where the noise started. It was a loud helicopter sound which I was sure was the wheel. I replaced the wheel and the sound lessened, but did not go away. After further inspection, a tire was bad (with a cut in it). I had two tires replaced and the other two looked just fine. They put the new ones on the back and the old ones (previously on the rear) to the front of the car, replacing the old front tires and the apparent problematic one. After this, the front passenger side is still making a slight vibration and noise at 60+MPH. Brakes are fine BTW.

Could this be a bad tire again? (possible belts from the impact of the pot hole although the tire was not on the rim that bent, but the same side just in the rear).

Wheel bearing already?

Any other ideas?

I would inspect your wheel bearing - The pot hole that destroyed your wheel could have also damaged the wheel bearing. Obviously the Genesis is RR drive vs. the car in the video, but you should get the basics out of the video.

Thank you for the reply!

How would I get the front wheel up to speed like in the video considering RWD? Is there another way to check the bearing?

Does it lessen... or get louder when loading / unloading that side on the highway?

For example,

At highway speeds... and the sound is consistent...do lane changes, change the pitch or tone of the sound?

If making a left turn (semi quick lane change) makes it worse, or no change (loading the right wheel, body of car / weight transfer to the right wheel)

and

a Right lane chagne does not (unloading the corner, making the weight transfer to the left side of the car)


I would suspect the wheel bearing

Do this a few times and REALLY LISTEN... turn of the Radio...A/C... make it quiet in the cabin

If you have a passenger in the rear... can they determine if the sound is coming from the rear of the car (I had one in my BMW that I swore was the front bearing....my daughter said it was the rear one where she sits.... she was right - and she was 5 years old at the time!)

I would take it in to the dealer and have them inspect the car. They will isolate the noise hopefully.

Thank you!

I have not noticed any difference under load, but I will try your suggestion this afternoon on the highway.

Any thought on possible internal (non-visible) tire damage? The tire currently on the right front was previously on the right rear which is the side that hit the Grand Canyon Size pot hole, disguised with water. My thought after some reading is that it may be internal damage.... I am going to move the new tires to the front tonight and take it out for a spin to see if there is a difference as to where the noise is coming from....

If the noise moves, then I guess its $400 more for 2 more tires... I am going to check the wheel for play while I have it up too.

Did you have the older tires rebalanced? I hit a pot hole last winter and had to rebalance both wheels on the passenger side. I too had a vibration from 80k to 12ok( 50-75mph) After balancing both passenger wheels, the vibration went away.

 

[floyd0101]

All of the tires were balanced, but I think that one may be out of round.

I moved the fronts to the rear last night and I think that the sound moved, but it was raining this morning so it was more difficult to tell with the noise. I am going to move the rears from side to side tonight and that should confirm it if the tire is bad as the sound will be coming from the driver's side instead...Also - I checked the wheel bearings with the old 6 and 12 trick and there was a little play but nothing crazy, although I know that test is not 100%.

Fingers crossed its the tires. If not, she is heading to the dealership on Monday. 57,000 miles, so just within the bumper to bumper warranty.

Update - There is some play in the front right wheel bearing. Did the old 6 and 12 check with it lifted up and it seems to have about 1/8-1/4 inch of play. I hear mixed ideas on this - some say that any play is bad and others say that up to 1/4 inch is ok...

Any thoughts? Next, I am going to compare to the left side and see if it has the same traits...

Curious how this ended and what the problem was.

i cant speak on how it ended up for this guy but any modern wheel bearing should have no play when trying to move the wheel like he did, from the sounds of it it most likely was the wheel bearing being bad
