Good morning, FordMan,

You are correct. It is a 2001. Both front hubs have been replaced so that rules that out. I've also low-tech checked the wiring by shorting the wires at the module connector then checking for resistance at the wheel. All four wheels read 0 ohms. Well, they do now. The wiring from the front right wheel was in terrible condition. I replaced the bottom 2 feet of wire to get successful continuity.
All that said, it's probably time to recheck.
I'm just getting set to throw some paint at the car this weekend. So long as I don't bugger that up too badly, I'll add the transmission kit to my short list of repairs. It does make sense from a preventative point of view.

Thanks again.
