I was going down the highway about 50 miles per hour. Heard a pop and my truck wheels kind of locked and then rolled on. I pulled over and got out and looked under the truck and found nothing. Went on to my location and when getting back in my truck I had no reverse. Had I had an 18 wheeler behind be this could have been a disaster. Have not put it in the shop yet. 2004 chevy z71 silverado.
