I replaced the left and right wheel hubs/bearings/speed sensors. A bearing squeaked and a speed sensor failed, so I just got over both. The quality of the piece is excellent, the fit is perfect, nothing more to say. If I were to do this job again I would order a replacement for the four mounting bolts (on each side) that hold the hub to the steering knuckle. They have a small head and spin to high torque and once they rust it's pretty questionable.
