Driving home this afternoon the steering became super heavy. I thought at first maybe a tire picked up a nail or something. I was getting dark the tires were fine. When i got home i opened the hood and the power steering belt was hanging down and not connected. I've never had one just come off. I'm going to do some digging in the morning to make sure nothing is damaged or having issues. Never seen this happen. Any suggestions or ideas? The pulley on the power steering turns freely so it's not as if it seized causing the belt to jump. All help appreciated.
