your grease leaking looks like you need to tighten the clamps...I know of owners packing these as a routine maintenence item... which is not the norm...

A Tech II or other ABS capable scan tool can tell you which sensor is bad. As jcAT said, fronts are bad more often than rears. The sensor within the hub can be bad, but the hub itself can be good. The sensors cannot be replaced without replacing the hub, unfortunately.
If your CV boot is not torn, just cut the clamp, repack the bearing with Cv joint grease, and put on a new clamp. I used two screw clamps on mine 15K miles ago, and it hasn't leaked a bit since. It's not a hard job at all, and much cheaper than a new axle.
