Volvo Repair: Volvo S60 Wheel Problem, power steering pump, volvo dealers

Question
Hi. I am owner of a Volvo s60 2.0T year 2004. The car has tires 215/16/55. The problem is that from the beginning the steering wheel was particularly heavy and the noise of the wheels when driving the car was intense (you can feel the tyres on the road). In the parking manoeuvres turning the steering wheel fast in a point near to the end it became still heavier (as if it was not servo). In the beginning the problem was intense only turning the steering wheel to left but now you can feel it in any direction  and noise have begun to be heard (when turning the steering wheel) when the car is cold. Also you can hear a metal noise from the right side (front and rear) at the acceleration from low rp/min or when you braking. Most worrying is that the car in Lefts turns with acceleration loses his accretion (grip) and gines the impression that will turn over. The volvo dealers service it cannot find what's going on, they agree that something is wrong but they dont know what. I would appreciate particularly any advice or information. I thank. Sorry for the poor english.

Answer
Well it sounds like you could have several problems going on.  The metal noise when cold sounds like you have a power steering pump issue, but the hard steering sounds like you have a steering rack issue.  It would be too hard to isolate the problem any further without seeing the car, and even then you have said they are having problems finding it.  Also check in the wheel well for rubbing marks in front of the strut.  As the steering stops wear out sometimes the tires will rub on the inside of the wheel well.  You would only hear that noise when turning the wheel all the way left or right however.  It is a 2004 so unless you have already driven 50,000 miles on the vehicle it will still be under warranty.  You may be able to get a loaner vehicle from the dealer so they can have more time trying to diagnose your problem.
