I was in the car with my dad a while back, he had a new BA Falcon, as we were driving along, heard a big clunk, but we thought it was just a branch as it was quite windy that day and there was debris all over the road. Eventually the power steering went, the battery light came on, it wouldnt idle, everything was phucked. Turns out the idler pulley had come clean off and caused the rest of the drive belt to get shredded up!
