That sounds like a wheel bearing to me- on these the wheel speed sensor is part of the wheel bearing assembly.
It will not always have play, even with the wheels off the ground- you have to go by listening to it. A wheel bearing will typically sound like it is coming from one side, and gets louder as you weight that side, lessening as you unweight it- so if the bad bearing is on the right side, and you turn right, it will go away, where if you turn left you put weight on the bad bearing and it will get louder. You can go down the highway and wiggle the steering back and forth to test for this.
I would have the ABS checked for faults and see what it says- that might pinpoint your issue (or it may be a separate issue, but getting it out of the picture may help) Looking into it, I wonder if the tone right on the CV joint may have broken loose? I had one just a few weeks ago on a vehicle, so it effectively made a ring of metal that spun around the axle when driving (and kept the speed sensor from working)
