Hi everyone, A couple of days ago I bought my first Commodore, a 2007 Calais 3.6 with 116,000 on the clock and I'm pretty stoked with it! Drives beautifully and is such a smooth and powerful beast compared to the '03 Astra 1.8 it replaced. But I've noticed with the Calais a strange noise coming from the front left hand side wheel; a sort of humming/vibration noise but only between 55-65km/h and 75-85km/h. I shifted into neutral to see if its gearbox related or an engine noise but that makes no difference. Just happens when the car is going at those speeds. Any ideas? I bought this car private and apart from that noise it drives very well. Cheers guys.
