Heavy steering when parking

[kevst183]

My x300 is suffering from the steering becoming heavy sometimes when parking. It doesn't do it all the time and it's fine when driving normally. I have changed the relay. Is it likely to be either power steering pump or steering rack?

just seen the date of this post but i am going to ask if you sorted this issue, and what it was as i have the same issue, when the engine is cold the steering at low speed is normal but as the engine and power steering fluid warms up the assistance is lost, i suspect in my case it is the steering pump as when you increase revs the assistance returns.
