Ford Falcon 2009: Power steering whine

My 2009 BF Falcon MKIII wagon has only done 41,000 km, but the power steering pump has a whine that can be heard over the engine noise at 2000 rpm and above. The dealer says it's normal and they even hear whines on later model cars, but I previously owned a 2002 BA wagon and the whine in that was much worse. I bought a replacement for that and fitted it and there was no more whine, so I know what a new one should sound like. I contacted Ford and asked them if they made cars that make this whine in the power steering pump and they just fobbed me off.
