    I had the same problem! Took it to the dealer (i work there) they thought it could've been a speed sensor. Turns out that that the sensor on the back of the wheel bearing was non-functional so you may have replaced the wheel bearing but if the connector wasn't attached properly it could be malfunctioning. The only sure fire way to fix it would be to get another wheel bearing.

    If you changed one recently the one on one of the other wheels could've gone bad.

    Or hook it up to an abs reader and check speed on sensors while driving
