03 Ford EB V8 Explorer ABS light intermittent

Did you clean the mounting surfaces to make sure the hub is running absolutely straight? If yes you probably have a defective bearing return it.

its one unit hub and bearing and abs in sealed assembly

First thing to do is have the computer scanned for trouble codes.

The ABS has been deactivated but the normal barkes are still active. This is why your brakes run fine now. You might have damaged the sensors or the tone ring. The tone ring is made up of teeth that the sensor reads. If one of them are damaged, the computer will miss diagnose your problem and the ABS light will turn on. Good luck!

it is on the side of the transmission case near the rear

i would say a wire more likely

Sounds like the ABS sensor has failed, or is unplugged. If someone did the work for you, take it back. Otherwise check the sensor on the right front. Replace as necessary. Also ask the Q at MyFordFreestyle.com

You can do it yourself just take your time:

1. Jack car up support with jack stands
2. take tire off
3. take caliper and brakes off
4. take rotor off
5. unbolt axle shaft nut at bearing hub

8. back side 3 10mm bolts unbolt
9. front side have to pry off bearing hub Assembly only beacuse has dirt in knuckle hole.
