Sounds like a pattern failure of ft wheel speed sensor.
Unplug the underhood connector, check sensor for continuity while flexing
the sensor wire along the length in the wheel well(There are two wires at the wheel,pad wear and wheel speed, easier to check with wheel off )
Easier with an assistant to hold the meter on the plug while you flex the wire.

The sensor wires develop an open spot from constant flexing over the years.
Replace faulty sensor, problem solved.

We've done a hundred fronts, 2 rears(in diff, almost never a problem).
