ABS all wheel drive on sometimes go off. When they come back in the wheel make strange noise or sometime when I drive around 35 miles they lock by the self. How I can fix? I went to couple mechanics and everybody said something different.

Hello,

It sounds like you have a front wheel bearing hub that is going out which effects the sensor and ABS/traction control system.To confirm lets run the codes to see which sensor is giving us trouble. I will also include a video on how to change the hub out on a similar car.
