This problem is driving me crazy. The car is 2012 with 53000 on the clock. It has developed a very loud rattle from the back end which seems to come from the passenger wheel. It has been in the garage and had new callipers, all brake pads replaced and now a new drive shaft. Annoying rattle still there!!!!! It starts off really quiet and then gets louder. If the car is jacked up and then let down again the noise disappears for a while and then is back again. Any ideas as my garage is baffled. Thanks.
