Hi Scotty, I love your videos I get a lot out of them. I have a 2020 Corolla when I’m going down the highway it makes like a humming pulsating noise. I had one shop look at the tires, they wiggled them nothing wiggles so I’m just wondering if it could be the wheel bearing or if you have any other ideas what it could be? I have a appointment tomorrow Thursday at the Toyota dealership for a routine maintenance, so I will have them look at it also. I’m always skeptical if the mechanics actually look at the vehicle or if they just skim over it, I’d hope that they are actually doing their job. Thanks brother for your advice.
I would hope they aren't bad after 2 years, did you slam a curb or something?
Also you mentioned two shops found nothing, they sound honest. Maybe have another shop check the balance & air pressure.
Inspect the tires. make sure you do not have nails in them and they are not worn unevenly. You could swap the front with rear ones and see if the noise changes.
I REALLY hope it's not the CVT.
Here's the surging humming kind
VIDEO WITH TIMESTAMP, here it's more extreme.
