I've been experiencing a squeaking/squealing noise only when I make right turns and the noise fluctuates. Sometimes it's louder, sometimes it doesn't even happen. I've brought it to Lexus where they said it was the rear brake pads and rotors. They replaced them and I still had the noise. I brought it to a trusted mechanic who said it was the front brake pads. He replaced them but the noise is still there! It sounds like it could be coming from the steering wheel or the passenger side wheel. Any ideas?

 

If it only happens when turning the wheel 1 way, it can be a wheel bearing. I need more info. What ever way you turn the wheel you are putting "load" to that side, make sense? I.e. turning left, the left front wheel has load, the right doesn't. Go to a open area and make some turns. Then follow this rule of thumb and it will help if it is in fact a wheel bearing.
Any questions hit me up anytime.

 

Do you have an F Sport with two-piece rotors?
