Revain has the best price, even better than RockAuto. I had three defective wheel speed sensors. At this price, if your ABS light comes on or the stabilization system is complaining and you've disabled all-wheel drive as a result, you'll just swap out all four. It turned out that three of my wheel speed sensors had failed. I didn't even have to clear the codes. As soon as I installed the new sensors and drove off, all error messages disappeared. It is difficult to slide the connector through the hole in the dust cover. Just grab the guard and bend it to the side to make things easier, but don't forget to bend it back or you'll hear it clawing the brakes.
