I just changed out the upper ball joints on my FJ today. The slip indicator light and the “abs” lights came on as I took the FJ out for a test drive does anyone know what this means? I unbolted the wire to the wheel sensor to keep loose before pressing on/off the ball joints and the wire and wire connection are still intact on all four wheel sensors. A few other things to consider would be that I picked up a lot of dust from two big trips in my rig and there was a lot of ice and slush picked up from the recent weather here in Texas, any input regarding these lights would be appreciated.
