What would cause a loose axle lug nut? I wonder if the work I had done end of February is the cause.....In February, a reputable shop replaced the front passenger cross member and the "control arm-front lower w/o BJ w/ Bushings" after pothole damage. After 1,000 miles of freeway driving in Mid March, another shop diagnosis is typed up as: "Axle bolted axle lug nut bearing destroyed. Damaged ABS sensor". Verbally he said it was loose 5 mm and he was able to realign the ABS sensor, but now I have to replace right front wheel bearing. I'm not sure if all this is connected.
