My abs light comes on around 70 MPH. There is a tapping sound coming from the front, I thought it might be a loose heat shield but cannot find one. I also have some vibration and a high pitch noise coming from my driver side rear. I know its allot but maybe someone has some advise.

My 97 Windstar did the same thing concerning ABS. My mechanic read the codes and determined which wheel was the culprit, but he never fixed it. I took all the wheels and hubs off one at a time and cleaned the abs sensor and everything else with brake cleaner. The cure lasted about 3 months. I bought the sensor from Rockauto.com and installed it and cured the problem. The bad sensor had a stripped bolt head (8-mm), and it took me 7 hours (yes, 7 hours), of applying WD-40, BP-blaster, torch, etc., but nothing worked. Eventually, had to drill out old bolt that held the sensor (it had rusted into the framing), and put in a new bigger bolt with lock washer and nut, but it worked. I noticed that sometimes the sensor is too close to the gear and rubs against it (causing ABS to come on), and sometimes sensor is too far away from the gear-causing ABS to come on. Sorry, but this is very bad engineering on Ford's part, but what else is new?

The sensor is sometimes too far away, and sometimes too close - on the same wheel? If so, I'd guess the bearings on that wheel are shot...

I wondered about that too. Could the toothed ring be installed at an angle?

No- I meant the sensors were too close or too far away on different wheels. Sorry
