Good point, and we've done that already. While driving the speeds shown for all but the right front are consistent. The right front reads an intermittency. Say you are travelling at 30mph. For a moment or two it shows 30, but then drops down to 2, or 5, or 12, or some other number.

We replaced the hub and sensor this morning just in case, no change. Leaning toward a wire short or maybe the ABS controller being bad.

I still don't understand why the left front brake locks up when you first start. That happens as a result of the ABS pump firing. After several times braking the ABS shuts down and the dash lights come on, and the LF brake is fine. Makes me suspect the controller.

Any other ideas? Tks.
