So Ive noticed a vibration thats progressively getting worse. When I'm doing between 20-40km I have a vibration and a whoomp noise kinda feels like I have a flat tire. Once I accelerate its still there faintly barely noticeable then again when I slow down the car vibrates and I hear that noise like I have a flat. Any ideas ?!?!?!?

 

Video?

 

Check tires. That would be a first step.

 

I was thinking/hoping it was a tire out of balance. But Womdering some other possibilities besides a wheel bearing
