Most likely ABS sensor wiring, with the arm's removed the strut is free to 'roam' and load up the wiring to the sensor. Some alternatives (assuming you separated the driveshaft from the hub) could be that the sensor ring got damaged, the sensor itself was damaged during that process or the hub bolt wasn't replaced and the drive shaft isn't properly 'home' causing mis-readings.
