Ok. Everyone knows I just replaced my front two ABS sensors. Here is what happening now. Start up roll out slow speeds less than 40 MPH the ABS and BRAKE lights remains off. Once I exceed 40 MPH they pop back on. I can pull over shut off the truck start up again and start rolling out and the light reset again. Once over 40 MPH it trips again. My old sensors works fine but had been broken in the leads. I solder and shrink tube then a few times and always was able to get the light back out. As for the rear speed sensor it dead on with my Garmin GPS so I really doubt I got a bad rear sensor.

Rear sensor is still function if the speedometer is dead on with the GPS then I say it working...

 

I had those symptoms with those sensors I gave you and the new ones I got with both unit bearings.

 

As CTCummins posted these are the sensors that cam in his unit bearings. But didn't work so I'm going to safely say the sensors are no good.

Sorry Mike

No problem. Just confirms your problem wasn't anything more than sensors being bad... Sad to see you bought a ABS computer over it. (Did you?)

No, the new sensors would intermittently cut out too. When hooked up to the expensive snap on tool, the ABS module would cycle. The ABS module was bad.
