How did you check the wheel speed sensors to be sure they are ok? Usually when a problem like this occurs, it is a wheel speed sensor that is dropping off right as the vehicle comes to a stop. The only way to be really sure is to watch each wheel speed sensor with a scanner to determine which one is dropping out. Usually it is a front sensor, but can be any. My advice would be to get it checked out by someone with a proper scanner. Normally a problem like this does not set a code, so you have to be able to 'see' which wheel is acting up with a scanner. After determining that, you can then go ahead and replace that part. Be sure to check the wiring harnesses to each sensor as well, as corrosion is a common problem too.

Thank you for your responds.The rear sensor had no reading on the scanner when the car was coming to stop.Change both bearings with sensors. OK.
