Got this one in today which is a bit of a wierd one but i'm sure someone else has come across it before . Customer complaining of a wheel bearing noise but only between 30-40 mph and abs light flashed once in past few weeks .Confirmed fault and sure enough it does sound like a wheel bearing noise but before and after these speeds no noise . Did basic mechanical checks but then remembered i had this one before on another vectra but customer didn't bother with fixing .Like the other car i put the launch on i think it was running 5.3 to check for fault codes (not present ) went into live data and everything looks ok but when tapped into abs system the noise isn't present any ideas guys? Thanks Regards John
