Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Is this sound produced while the vehicle is in motion? No noise when travelling straight or turning to the right?
Unfortunately this type of noise is indicative of a failing wheel bearing. Loading the wheel bearing by turning one way and unloading it by turning the other way will increase or diminish the noise produced. The wheel bearing will need to be replaced to fix the problem.
Not really likely that it is anything else. When the vehicle is on the lift there is no way to load the bearing to get it to make noise. Eventually if you drive the vehicle long enough, the wear in the bearing will become obvious, even with the vehicle on the lift. I don't suggest driving it this long. I feel you are safe in replacing the bearing to fix the noise.
