1. my car has vibration problem when i bought it
2. I did 4 wheels balance, and changed 4 brake rotors
3. bought new rims with previous tyres and balanced
4. bought hub adapters
5. just rotate the wheels between front and rear
still has the problem.
i record a video here, you can here some noise from 20s - 24s when I accelerate the car (around 50-70 km/h) and the ground is not smooth. this noise is from rear. I assume this is caused by same failure.
